Title: Conversion Efficiencies of Heteronuclear Feshbach Molecules

Authors: Shohei Watabe, and Tetsuro Nikuni

Categories: cond-mat.other

Comments: 43 pages, 32 figures

\\

We study the conversion efficiency of heteronuclear Feshbach molecules in

population imbalanced atomic gases formed by ramping the magnetic field

adiabatically. We extend the recent work [J. E. Williams et al., New J. Phys.,

8, 150 (2006)] on the theory of Feshbach molecule formations to various

combinations of quantum statistics of each atomic component. A simple

calculation for a harmonically trapped ideal gas is in good agreement with the

recent experiment [S. B. Papp and C. E. Wieman, Phys. Rev. Lett., 97, 180404

(2006)] without any fitting parameters. We also give the conversion efficiency

as an explicit function of initial peak phase space density of the majority

species for population imbalanced gases. We find that quantum statistics of

atoms is quite important in determing the maximum conversion efficiency.

Using a magnetic-field controlled Feshbach resonance, we create ultracold

fermionic molecules starting from an ultracold Bose-Fermi atom gas mixture. The

resulting mixture of atoms and weakly bound molecules provides a rich system

for studying few-body collisions because of the variety of atomic collision

partners for molecules; either bosonic, fermionic, or distinguishable atoms. We

study the inelastic loss of the fermionic molecules as a function of the

heteronuclear scattering length and find the quantum statistics of the

particles involved in the collision has a dramatic effect on the loss rates

near the Feshbach resonance. In particular, we find it is possible to realize a

molecule lifetime as long as 100 ms near the Feshbach resonance.

For spiral wavevectors past a critical value, spin wave excitation energies

become imaginary indicating a dynamical instability. We construct phase

\\

Recently, a homogeneous superfluid state with a single gapless Fermi surface

was predicted to be the ground state of an ultracold Fermi gas with spin

population imbalance in the regime of molecular Bose-Einstein condensation. We

study vortices in this novel state using a symmetry-based effective field

theory, which captures the low-energy physics of gapless fermions and

superfluid phase fluctuations. This theory is applicable to all spin-imbalanced

ultracold Fermi gases in the superfluid regime, regardless of whether the

original fermion pairing interaction is weak or strong. We find a remarkable,

unconventional form of the interaction between vortices. The presence of

gapless fermions gives rise to a spatially oscillating potential, akin to the

RKKY indirect-exchange interaction in non-magnetic metals. We compare the

parameters of the effective theory to the experimentally measurable quantities

and further discuss the conditions for the verification of the predicted new

feature. Our study opens up an interesting question as to the nature of the

vortex lattice resulting from the competition between the usual repulsive

logarithmic (2D Coulomb) and predominantly attractive fermion-induced

interactions.

Title: Equilibrium Properties of Mixtures of Bosons and Fermions

Comments: 32 pages including abstract and title pages

\\

Partial Quantum Nearest Neighbor Probability Density Functions (PQNNPDF's)

are formulated for the purpose of determining the behavior of quantum mixed

systems in equilibrium in a manner analogous to that provided for classical

multi-component systems. Developments in partial quantum m-tuplet distribution

functions, a generalization of the partial quantum radial distribution

function, along with their relationship to PQNNPDF's, are briefly elucidated.

The calculation of statistical thermodynamic properties of quantum mixtures is

presented for arbitrary material systems. Application to the limiting case of

dilute, weakly correlated quantum gas mixtures has been outlined and the second

virial coefficient is derived. The case of dilute strongly degenerate mixtures

is also addressed, providing an expression for the PQNNPDF applicable in this

thermodynamic regime.

Categories: cond-mat.other cond-mat.stat-mech

\\

One of the most promising applications of ultracold gases in optical lattices

is the possibility to use them as quantum emulators of more complex condensed

matter systems. We provide benchmark calculations, based on exact quantum Monte

Carlo simulations, for the emulator to be tested against. We report results for

the ground state phase diagram of the two-dimensional Bose-Hubbard model at

unity filling factor. We precisely trace out the critical behavior of the

system and resolve the region of small insulating gaps, \Delta<< J. The

critical point is found to be (J/U)_c=0.05974(3), in perfect agreement with the

result of Ref. 1. We present data for the effective mass of particle and hole

excitations inside the insulating phase. We obtain the critical temperature for

the superfluid-normal transition at unity filling factor. We also propose a

simple and efficient cooling protocol.

Title: Quantum degenerate two-species Fermi-Fermi mixture coexisting with a

Bose-Einstein condensate

Authors: M. Taglieber, A.-C. Voigt, T. Aoki, T.W. H\"ansch, K. Dieckmann

Categories: cond-mat.other

\\

We report on the generation of a quantum degenerate Fermi-Fermi mixture of

two different atomic species. The quantum degenerate mixture is realized

employing sympathetic cooling of fermionic Li-6 and K-40 gases by an

evaporatively cooled bosonic Rb-87 gas. We describe the combination of trapping

and cooling methods that proved crucial to successfully cool the mixture. In

particular, we study the last part of the cooling process and show that the

efficiency of sympathetic cooling of the Li-6 gas by Rb-87 is increased by the

presence of K-40 through catalytic cooling. Due to the differing physical

properties of the two components, the quantum degenerate Li-6 K-40 Fermi-Fermi

mixture is an excellent candidate for a stable, heteronuclear system allowing

to study several so far unexplored types of quantum matter.

Comments: 4 pages, 3 figures

\\

We show that dark solitons in 1D bose systems may be excited by resonant

absorption of single quanta of an external ac field. The energy of the quantum

$\hbar\omega$ should be slightly blue-detuned from the energy of a soliton with

momentum $\hbar q$, where $q$ is the external field wavenumber $q$. We

calculate the absorption cross-section and show that it has power-law

dependence on the frequency detuning. This reflects the quantum nature of the

absorption process and the orthogonality catastrophe phenomenon associated with

it.

We propose a setup in which Andreev-like reflections predicted for 1D

optical lattice. Using time-dependent Density Matrix Renormalisation Group

methods we analyse the wavepacket dynamics as a density excitation propagates

across a boundary in the interaction strength. These phenomena exhibit good

correspondence with predictions from Luttinger liquid models and could be

observed in current experiments in the context of the Bose-Hubbard model.

Title: Effect of the lattice alignment on Bloch oscillations of a Bose-Einstein

condensate in a square optical lattice

Authors: M.-C. Chung and A. R. Kolovsky

Categories: cond-mat.supr-con cond-mat.mes-hall

Comments: 4 pages, 3 figures

\\

We consider a Bose-Einstein condensate of ultracold atoms loaded into a

square optical lattice and subject to a static force. For vanishing atom-atom

interactions the atoms perform periodic Bloch oscillations for arbitrary

direction of the force. We study the stability of these oscillations for

non-vanishing interactions, which is shown to depend on an alignment of the

force vector with respect to the lattice crystallographic axes. If the force is

aligned along any of the axes, the mean field approach can be used to identify

the stability conditions. On the contrary, for a misaligned force one has to

employ the microscopic approach, which predicts periodic modulation of Bloch

oscillations in the limit of a large forcing.

Superfluid-insulator transition in an ultracold Fermi gas in the external

results for BEC side of the diagram are also valid for the superfluid-insulator

We investigate the dynamics of a coupled atom-field system. Atoms trapped in

a double-well potential interact dispersively with a damped and driven cavity

mode. The atomic interwell tunneling couples to the dynamics of the field

because of the position dependent atom-field coupling. The system is a close

analogue of the Dicke model in the dispersive regime and is characterized by

two incommensurate time scales, the atomic interwell tunneling rate and the

cavity loss rate. This results in drastically different behaviors in the

short-time and long-time intervals.

Atomic collisions are included in an interacting system of optical fields and

on the system stability. Also a study of the degree of entanglement between

atomic and optical fields is made. We found that, for an atomic field initially

in a vacuum state and optical field in a coherent state, the degree of

entanglement does not depend on the optical field intensity or phase. We show

that in conditions of exponential instability the system presents at long times

two distinct stationary degree of entanglement with collisions affecting only

one of them.

Lewenstein

Categories: cond-mat.other quant-ph

Comments: 13 pages, 6 figures

\\

We investigate a paradigm example of cavity quantum electrodynamics with many

body systems: an ultracold atomic gas inside a pumped optical resonator. In

particular, we study the stability of atomic insulator-like states, confined by

the mechanical potential emerging from the cavity field spatial mode structure.

As in open space, when the optical potential is sufficiently deep, the atomic

gas is in the Mott-like state. Inside the cavity, however, the potential

depends on the atomic distribution, which determines the refractive index of

the medium, thus altering the intracavity field amplitude. We derive the

effective Bose-Hubbard model describing the physics of the system in one

dimension and study the crossover between the superfluid -- Mott insulator

quantum states. We determine the regions of parameters where the atomic

insulator states are stable, and predict the existence of overlapping stability

regions corresponding to competing insulator-like states. Bistable behavior,

controlled by the pump intensity, is encountered in the vicinity of the shifted

cavity resonance.

In this paper we discuss Bose-Einstein spinor condensates for F=1 atoms in

the context of 87Rb, as studied experimentally by the Stamper-Kurn group

[Sadler et al. Nature (2006)]. The dynamical quantum fluctuations of a sample

that starts as a condensate of N atoms in a pure F=1, m_F = 0 state are

described in analogy to the `two-mode squeezing' of quantum optics in terms of

an su(1,1) algebra. In this system the initial m_F=0 condensate acts as a

source (`pump') for the creation pairs of m_F =+1,-1 atoms. We show that even

though the system as a whole is described by a pure state with zero entropy,

the reduced density matrix for the m_F = +1 degree of freedom, obtained by

tracing out the m_F = -1,0 degrees of freedom, corresponds to a thermal state.

Furthermore, these quantum fluctuations of the initial dynamics of the system

provide the seeds for the formation of domains of ferromagnetically aligned

spins.

In spite of the fact that statistical predictions of quantum theory (QT) can

only be tested if large amount of data is available a claim has been made that

QT provides the most complete description of an individual physical system.

Einstein's opposition to this claim and the paradox he presented in the article

written together with Podolsky and Rosen in 1935 inspired generations of

physicists in their quest for better understanding of QT. Seventy years after

EPR article it is clear that without deep understanding of the character and

limitations of QT one may not hope to find a meaningful unified theory of all

physical interactions, manipulate qubits or construct a quantum computer. In

this paper we present shortly the EPR paper and the discussion which followed

it. By emphasizing the difference between quantum phenomena and hypothetical

invisible sub phenomena we show that paradoxes are only found if incorrect

models of sub phenomena are used. The violation of Bell and CHSH inequalities

demonstrate clearly that "an entangled pair of photons" resembles neither "a

pair of Bertlmann's socks" nor "a pair of fair and random dices". Finally we

rephrase the EPR question by asking whether QT provides the complete

description of experimental data.

Title: Dynamics, dephasing and clustering of impurity atoms in Bose-Einstein

condensates

Authors: Alexander Klein, Martin Bruderer, Stephen R. Clark, and Dieter Jaksch

Categories: quant-ph

Comments: 22 pages, 8 figures

\\

We investigate the influence of a Bose-Einstein condensate (BEC) on the

properties of immersed impurity atoms, which are trapped in an optical lattice.

Assuming a weak coupling of the impurity atoms to the BEC, we derive a quantum

master equation for the lattice system. In the special case of fixed impurities

with two internal states the atoms represent a quantum register and the quantum

master equation reproduces the exact evolution of the qubits. We characterise

the qubit dephasing which is caused by the interspecies coupling and show that

the effect of sub- and superdecoherence is observable for realistic

experimental parameters. Furthermore, the BEC phonons mediate an attractive

interaction between the impurities, which has an important impact on their

spatial distribution. If the lattice atoms are allowed to move, there occurs a

sharp transition with the impurities aggregating in a macroscopic cluster at

experimentally achievable temperatures. We also investigate the impact of the

BEC on the transport properties of the impurity atoms and show that a crossover

from coherent to diffusive behaviour occurs with increasing interaction

strength.

We propose a novel protocol for the creation of Schr\"odinger cat states

require switching on and off nonlinear interactions in the system. We predict

this protocol to allow the creation of multiatom SCS by measuring the number of

atoms coherently outcoupled from a two-component (spinor) Bose-Einstein

condensate.
