Title: Range Corrections to Three-Body Observables near a Feshbach Resonance

Authors: Lucas Platter, Chen Ji, Daniel R. Phillips

Categories: cond-mat.other

Comments: 28 pages, 3 figures

\\

A non-relativistic system of three identical particles will display a rich

set of universal features known as Efimov physics if the scattering length a is

much larger than the range l of the underlying two-body interaction. An

appropriate effective theory facilitates the derivation of both results in the

|a| goes to infinity limit and finite-l/a corrections to observables of

interest. Here we use such an effective-theory treatment to consider the impact

of corrections linear in the two-body effective range, r_s on the three-boson

bound-state spectrum and recombination rate for |a| much greater than |r_s|. We

do this by first deriving results appropriate to the strict limit |a| goes to

infinity in coordinate space. We then extend these results to finite a using

once-subtracted momentum-space integral equations. We also discuss the

implications of our results for experiments that probe three-body recombination

in Bose-Einstein condensates near a Feshbach resonance.

Title: Spontaneous recoil effects of optical pumping on trapped atoms

Authors: S. Wallentowitz and P.E. Toschek

Categories: quant-ph

Comments: 21 pages, 6 figures

\\

The recoil effects of spontaneous photon emissions during optical pumping of

a trapped three-level atom are exactly calculated. Without resort to the

Lamb-Dicke approximation, and considering arbitrary detuning and saturation of

the pump laser, the density of recoil shifts in phase space is derived. It is

shown that this density is not of Gaussian shape, and that it becomes isotropic

in phase space only for a branching ratio corresponding to fluorescence

scattering but unfavorable for optical pumping. The dependence of its

anisotropy on the laser saturation is discussed in the resonant case, and the

mapping of moments of the atom's center-of-mass motion due to the pumping is

presented. Moreover, it is shown how optimum parameters for protecting the

center-of-mass quantum state from pump-induced disturbance depend on the

specific property to be protected.

Title: Topological Entropy of Quantum Hall States in Rotating Bose Gases

Authors: Alexis G. Morris David L. Feder

Categories: cond-mat.mes-hall

Comments: 4 pages, 4 figures

\\

Through exact numerical diagonalization, the von Neumann entropy is

calculated for the Laughlin and Pfaffian quantum Hall states in rotating

interacting Bose gases at zero temperature in the lowest Landau level limit.

The particles comprising the states are indistinguishable, so the required

spatial bipartitioning is effected by tracing over a subset of single-particle

orbitals. The topological entropy is then extracted through a finite-size

scaling analysis. The results for the Laughlin and the Pfaffian states agree

with the expected values of $\ln\sqrt{2}$ and $\ln\sqrt{4}$, respectively.

Title: Stability of the fermionic gases close to a p-wave Feshbach resonance

Authors: J. Levinsen, N. R. Cooper, and V. Gurarie

Categories: cond-mat.supr-con cond-mat.other

\\

We study the stability of the paired fermionic p-wave superfluid made out of

identical atoms all in the same hyperfine state close to a p-wave Feshbach

resonance. First we reproduce known results concerning the lifetime of a 3D

superfluid, in particular, we show that it decays at the same rate as its

interaction energy, thus precluding its equilibration before it decays. Then we

proceed to study its stability in case when the superfluid is confined to 2D by

means of an optical harmonic potential. We find that the relative stability is

somewhat improved in 2D in the BCS regime, such that the decay rate is now

slower than the appropriate interaction energy scale. The improvement in

stability, however, is not dramatic and one probably needs to look for other

mechanisms to suppress decay to create a long lived 2D p-wave fermionic

superfluid.

Title: Topological quantum phase transitions of ultracold fermions in optical

lattices

Authors: R. W. Cherng, C. A. R. S\'a de Melo

Categories: cond-mat.str-el

Comments: 4 pages, 3 figures

\\

We consider the possibility of topological quantum phase transitions of

ultracold fermions in optical lattices, which can be studied as a function of

interaction strength or atomic filling factor (density). The phase transitions

are connected to the topology of the elementary excitation spectrum, and occur

only for non-zero angular momentum pairing (p-wave, d-wave and f-wave), while

they are absent for s-wave. We construct phase diagrams for the specific

example of highly anisotropic optical lattices, where the proposed topological

phase transitions are most pronounced. To characterize the existence of these

topological transitions, we calculate several measurable quantities including

momentum distribution, quasi-particle excitation spectrum, atomic

compressibility, superfluid density, and sound velocities.

Title: Genuine phase diffusion of a Bose-Einstein condensate in the

microcanonical ensemble: A classical field study

Authors: Alice Sinatra (LKB - Lhomond), Yvan Castin (LKB - Lhomond)

Categories: cond-mat.other

Comments: 9 pages, 6 figures

\\

Within the classical field model, we find that the phase of a Bose-Einstein

condensate undergoes a true diffusive motion in the microcanonical ensemble,

the variance of the condensate phase change between time zero and time $t$

growing linearly in $t$. The phase diffusion coefficient obeys a simple scaling

law in the double thermodynamic and Bogoliubov limit. We construct an

approximate calculation of the diffusion coefficient, in fair agreement with

the numerical results over the considered temperature range, and we extend this

approximate calculation to the quantum field.

\\

We study the role played by the magnetic dipole interaction in an atomic

interferometer based on an alkali Bose-Einstein condensate with tunable

scattering length. We tune the s-wave interaction to zero using a magnetic

Feshbach resonance and measure the decoherence of the interferometer induced by

the weak residual interaction between the magnetic dipoles of the atoms. We

prove that with a proper choice of the scattering length it is possible to

compensate for the dipolar interaction and extend the coherence time of the

interferometer. We put in evidence the anisotropic character of the dipolar

interaction by working with two different experimental configurations for which

the minima of decoherence are achieved for a positive and a negative value of

the scattering length, respectively. Our results are supported by a theoretical

model we develop. This model indicates that the magnetic dipole interaction

should not represent a serious source of decoherence in atom interferometers

based on Bose-Einstein condensates.

Title: Vortices near the Mott phase of a trapped Bose-Einstein condensate

Authors: Daniel S. Goldbaum, Erich J. Mueller

Categories: cond-mat.other

Comments: Material from arXiv:0807.3609 formatted for journal submission

\\

We present a theoretical study of vortices within a harmonically trapped

Bose-Einstein condensate in a rotating optical lattice. We find that proximity

to the Mott insulating state dramatically effects the vortex structures. To

illustrate we give examples in which the vortices: (i) all sit at a fixed

distance from the center of the trap, forming a ring, or (ii) coalesce at the

center of the trap, forming a giant vortex. We model time-of-flight expansion

to demonstrate the experimental observability of our predictions.

Title: Raman Coupling of Zeeman Sublevels in an Alkali Bose Condensate

Authors: K. C. Wright, L. S. Leslie, and N. P. Bigelow

Categories: cond-mat.other

Comments: 12 pages, 16 figures

\\

We investigate amplitude and phase control of the components of the spinor

order parameter of a 87Rb Bose-Einstein condensate. By modeling the interaction

of the multilevel atomic system with a pair of Raman-detuned laser pulses, we

show that it is possible to construct a pulse-sequence protocol for producing a

desired state change within a single Zeeman manifold. We present several

successful elementary tests of this protocol in both the F = 1 and F = 2 Zeeman

manifolds of 87Rb using the D1 transitions. We describe specific features of

the interaction which are important for multimode, spatially-varying field

configurations, including the role of state-dependent, light-induced

potentials.

Title: Radio-frequency-driven dipole-dipole interactions in spatially separated

volumes

Authors: Atreju Tauschinsky, C. S. E. van Ditzhuijzen, L. D. Noordam, H. B. van

Linden van den Heuvell

Categories: quant-ph

\\

Radio-frequency (rf) fields in the MHz range are used to induce resonant

energy transfer between cold Rydberg atoms in spatially separated volumes.

After laser preparation of the Rydberg atoms, dipole-dipole coupling at 33 GHz

excites the 49s atoms in one cylinder to the 49p state while the 41d atoms in

the second cylinder are transferred down to the 42p state. The external

rf-field brings this energy transfer into resonance. The strength of this

interaction has been investigated as a function of amplitude and frequency of

the rf-field and as a function of a static field offset. multi-photon

transitions up to fifth order as well as selection rules prohibiting the

process at certain fields have been observed. The width of the resonances has

been reduced compared to earlier results by switching off external magnetic

fields of the magneto-optical trap. All features are well reproduced by

theoretical calculations taking strong the strong ac-Stark shift due to the rf

field into account.

Title: Spin-Domain Formation in Antiferromagnetic Condensates

Authors: Michal Matuszewski, Tristram J. Alexander, Yuri S. Kivshar

Categories: cond-mat.other

\\

Antiferromagnetic condensates are generally believed not to display

modulational instability and subsequent spin-domain formation. Here we

demonstrate that in he presence of a homogeneous magnetic field

antiferromagnetic spin-1 Bose-Einstein condensates can undergo spatial

modulational instability followed by the subsequent generation of spin domains.

Employing numerical simulations for realistic conditions, we show how this

novel effect can be observed in sodium condensates confined in an optical trap.

Finally, we link this instability and spin-domain formation with stationary

modes of the condensate.

Title: Hartree-Fock-Bogoliubov Theory of Polarized Fermi Systems

Authors: George Bertsch, Jacek Dobaczewski, Witold Nazarewicz, Junchen Pei

Categories: cond-mat.supr-con nucl-th

Comments: 9 RevTeX pages, 3 figures, submitted to Physical Review A

\\

Condensed Fermi systems with an odd number of particles can be described by

means of polarizing external fields having a time-odd character. We illustrate

how this works for Fermi gases and atomic nuclei treated by density functional

theory or Hartree-Fock-Bogoliubov (HFB) theory. We demonstrate that by

introducing two chemical potentials for different superfluid components, one

can change the particle-number parity of the underlying quasiparticle vacuum.

Formally, this method is a variant of non-collective cranking, and the

procedure is equivalent to the so-called blocking. Relations between the

two-chemical-potential method and the cranking approximation for Fermi gases

and nuclei are discussed.

Title: Fermions with attractive interactions on optical lattices and what they

imply for correlated systems

Authors: Chih-Chun Chien, Qijin Chen, and K. Levin

Categories: cond-mat.other cond-mat.str-el

Comments: 10 pages, 5 figures

\\

In this paper we address the behavior of the superfluid transition

temperature $T_c$ in the attractive Hubbard model. We study systematically the

effects of pairing fluctuations and address all filling fractions over the

entire range of attractive interaction strength. While the attractive Hubbard

model can be regarded as the generalization of BCS to Bose Einstein

condensation (BEC) crossover to a lattice, we find that the BEC limit of this

Hubbard model is very different from that of jellium, owing to the strong

inter-site repulsion between pairs, which becomes important near half filling

when the on-site attraction is strong. A central conclusion of our work is that

in a lattice, around half filling, the smooth evolution from the BCS to the BEC

limits is interrupted. For the attractive Hubbard model, $T_c$ vanishes when

the system approaches the bosonic regime with increasing interaction strength.

We suggest that the vanishing of $T_c$ at strong coupling strength may signal a

quantum critical transition to another form of superfluid not continuously

connected to a BCS-like phase. We present a simple variational ansatz for the

ground state in this more strongly coupled superfluid. We further generalize

the (s-wave) Hubbard model to d-wave pairing and address issues of potential

relevance to high temperature superconductors. For the d-wave case, we present

a phase diagram and show that here too, one observes a vanishing of $T_c$ when

the pairing onset temperature $T^*$ becomes sufficiently large. We suggest that

future experiments on ultracold fermions in optical lattices should not be

exclusively limited to the repulsive Hubbard model, but should address the

attractive model in order to elucidate features of high temperature

superconductivity.

Title: Exact relation between spin squeezing and single-particle coherence in

two-component Bose-Einstein condensates with Josephson coupling

Authors: G. R. Jin and C. K. Law

Categories: cond-mat.other

Comments: 4 figures, revtex4

\\

We investigate spin squeezing of a two-mode boson system with a Josephson

coupling. An exact relation between the squeezing and the single-particle

coherence is discovered, which provides an indirect way to measure the

squeezing by readout the coherence in atomic interference experiments. We prove

explicitly that the squeezing is just along the z axis, indicating the

appearance of number-squeezed state. Power laws of the strongest squeezing and

the optimal coupling with particle number $N$ are obtained based upon a wide

range of numerical simulations.

Superconductors are considered in view of applications to atom chip devices.

The main features of magnetic traps based on superconducting wires in the

Meissner and mixed states are discussed. The former state may mainly be

interesting for improved atom optics, while in the latter, cold atoms may

provide a probe of superconductor phenomena. The properties of a magnetic side

guide based on a single superconducting strip wire placed in an external

magnetic field are calculated analytically and numerically. In the mixed state

of type II superconductors, inhomogeneous trapped magnetic flux, relaxation

processes and noise caused by vortex motion are posing specific challenges for

atom trapping.

Title: Phonon-induced artificial magnetic fields

Authors: Alexander Klein and Dieter Jaksch

Categories: quant-ph

Comments: 6 pages, 4 figures

\\

We investigate the effect of a rotating Bose-Einstein condensate on a system

of immersed impurity atoms trapped by an optical lattice. We analytically show

that for a one-dimensional, ring-shaped setup the coupling of the impurities to

the Bogoliubov phonons of the condensate leads to a non-trivial phase in the

impurity hopping. The presence of this phase can be tested by observing a drift

in the transport properties of the impurities. These results are quantitatively

confirmed by a numerically exact simulation of a two-mode Bose-Hubbard model.

We also give analytical expressions for the occurring phase terms for a

two-dimensional setup. The phase realises an artificial magnetic field and can

for instance be used for the simulation of the quantum Hall effect using atoms

in an optical lattice.

Title: Coherent population trapping in a dressed two-level atom via a

bichromatic field

Authors: Peng Li, Qun Zhang, Xi-Jing Ning and J. Q. You

Categories: physics.optics physics.atom-ph

Comments: 14 pages, 6 figures

\\

We show theoretically that by applying a bichromatic electromagnetic field,

the dressed states of a monochromatically driven two-level atom can be pumped

into a coherent superposition termed as dressed-state coherent population

trapping. Such effect can be viewed as a new doorknob to manipulate a two-level

system via its control over dressed-state populations. Application of this

effect in the precision measurement of Rabi frequency, the unexpected

population inversion and lasing without inversion are discussed to demonstrate

such controllability.
