Hi subscribers,

My apologies for the lateness of this week's email. The semester started here

at the beginning of last week, and this year I've had some previously unfamiliar

duties that have soaked up all my time and then some. Firstly I developed a

contextualised lab on projectile motion based around frogs (for the biologists),

and then I've had to pick up supervising the proper first year physics labs on

top of running our stat mech course. It's been interesting given that I think

the last time I tried to do some experimental physics was some saturated

absorption spectroscopy in my own undergraduate degree. (Apart from being the

person looking through the IR viewer when we first got the Rb MOT running in the

UQ lab back in 2002, which doesn't really count I think!)

This week (well, almost two weeks ago) sees 18 new abstracts, and 18

replacements:

Title: Introduction to FFLO phases and collective mode in the BEC-BCS crossover

Authors: R.Combescot

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

Comments: 20 pages, to be published in the Proceedings of the 2006 Enrico Fermi

Summer School on "Ultracold Fermi gases", organized by M. Inguscio, W.

Ketterle and C.Salomon (Varenna, Italy, June 2006)

Subj-class: Superconductivity; Soft Condensed Matter

\\

The main focus of this paper is a discussion of what might happen in a BCS

superfluid when there is an imbalance between the two populations of fermionic

particles forming Cooper pairs, having in mind the case of ultracold Fermi

gases. In the last part the evolution in the BEC-BCS crossover of the

collective mode arising in such a superfluid (with balanced atomic populations)

is briefly considered.

Title: Trapping and observing single atoms in the dark

Authors: T. Puppe, I. Schuster, A. Grothe, A. Kubanek, K. Murr, P.W.H. Pinkse,

and G. Rempe

Categories: quant-ph

\\

A single atom strongly coupled to a cavity mode is stored by

three-dimensional confinement in blue-detuned cavity modes of different

longitudinal and transversal order. The vanishing light intensity at the trap

center reduces the light shift of all atomic energy levels. This is exploited

to detect a single atom by means of a dispersive measurement with 90%

confidence in 0.030 ms, limited by the photon-detection efficiency. As the atom

switches resonant cavity transmission into cavity reflection, the atom can be

detected while scattering only a few spontaneous photons.

We study the light generated by spontaneous emission into a mode of a cavity

QED system under weak excitation of the orthogonally polarized mode. Operating

in the intermediate regime of cavity QED with comparable coherent and

decoherent coupling constants, we find an enhancement of the emission into the

undriven cavity mode by more than a factor of 18.5 over that expected by the

solid angle subtended by the mode. A model that incorporates three atomic

levels and two polarization modes quantitatively explains the observations.

Title: Quantum states for Heisenberg limited interferometry

Authors: H. Uys and P. Meystre

Categories: quant-ph

Comments: 10 pages, 6 figures

\\

The phase resolution of interferometers is limited by the so-called

Heisenberg limit, which states that the optimum phase sensitivity is inversely

proportional to the number of interfering particles $N$, a $1/\sqrt{N}$

improvement over the standard quantum limit. We have used simulated annealing,

a global optimization strategy, to systematically search for quantum

interferometer input states that approach the Heisenberg limited uncertainty in

estimates of the interferometer phase shift. We compare the performance of

these states to that of other non-classical states already known to yield

Heisenberg limited uncertainty.

Title: On the Transport of Atomic Ions in Linear and Multidimensional Ion Trap

Arrays

Authors: D. Hucul, M. Yeo, S. Olmschenk, C. Monroe, W.K. Hensinger, J. Rabchuk

Categories: quant-ph

Comments: 70 pages, 35 figures

\\

Trapped atomic ions have become one of the most promising architectures for a

quantum computer, and current effort is now devoted to the transport of trapped

ions through complex segmented ion trap structures in order to scale up to much

larger numbers of trapped ion qubits. This paper covers several important

issues relevant to ion transport in any type of complex multidimensional rf

(Paul) ion trap array. We develop a general theoretical framework for the

application of time-dependent electric fields to shuttle laser-cooled ions

along any desired trajectory, and describe a method for determining the effect

of arbitrary shuttling schedules on the quantum state of trapped ion motion. In

addition to the general case of linear shuttling over short distances, we

introduce issues particular to the shuttling through multidimensional

junctions, which are required for the arbitrary control of the positions of

large arrays of trapped ions. This includes the transport of ions around a

corner, through a cross or T junction, and the swapping of positions of

multiple ions in a laser-cooled crystal. Where possible, we make connection to

recent experimental results in a multidimensional T junction trap, where

arbitrary 2-dimensional transport was realized.

Title: Quantum theory of degenerate $\chi^{(3)}$ two-photon state

Authors: Jun Chen, Kim Fook Lee, and Prem Kumar

Categories: quant-ph

Comments: 8 pages, 3 figures

\\

We developed a quantum theory for degenerate $\chi^{(3)}$ two-photon state

generated from optical fiber, and compared the theory predictions with an

experimental result which exhibits a Hong-Ou-Mandel dip visibility of around

94%. Excellent agreement between theory and experiment has been achieved, and

we attribute the missing 6% visibility mainly to spatial mode mismatch between

signal and idler photons at the beamsplitter.

\\

We present a simple two-dimensional model of a $p_x+ip_y$ superfluid in which

the mass flow that gives rise to the intrinsic angular momentum is easily

calculated by numerical diagonalization of the Bogoliubov-de Gennes operator.

We find that, at zero temperature and for constant director $\bf l$, the mass

flow closely follows the Ishikawa-Mermin-Muzikar formula ${\bf j}_{\rm mass}=

\frac 12 {\rm curl} (\rho \hbar {\bf l}/2)$.

We have developed a mean-field model to describe the dynamics of a

non-equilibrium Bose-Einstein condensate of exciton-polaritons in a

semiconductor microcavity. The spectrum of elementary excitations around the

stationary state is analytically studied in different geometries. A diffusive

behaviour of the Goldstone mode is found in the spatially homogeneous case and

new features are predicted for the Josephson effect in a two-well geometry.

We report the magnetic confinement of neutral, ground state hydroxyl radicals

(OH) at a density of $\sim3\times10^{3}$ cm$^{-3}$ and temperature of $\sim$30

mK. An adjustable electric field of sufficient magnitude to polarize the OH is

superimposed on the trap in either a quadrupole or homogenous field geometry.

The OH is confined by an overall potential established via molecular state

mixing induced by the combined electric and magnetic fields acting on the

molecule's electric dipole and magnetic dipole moments, respectively. An

effective molecular Hamiltonian including Stark and Zeeman terms has been

constructed to describe single molecule dynamics inside the trap. Monte Carlo

simulation using this Hamiltonian accurately models the observed trap dynamics

in various trap configurations. Confinement of cold polar molecules in a

magnetic trap, leaving large, adjustable electric fields for control, is an

important step towards the study of low energy dipole-dipole collisions.

We present various planar magnetic designs that create points above the plane

where the magnitude of the static magnetic field is a local minimum. Structures

with these properties are of interest in the disciplines of neutral atom

confinement, magnetic levitation, and magnetic resonance imaging. Each planar

permanent magnet design is accompanied by the equivalent planar single

non-crossing conductor design. Presented designs fall into three categories

producing: a) zero value magnetic field magnitude point minima, b) non-zero

magnetic field magnitude point minima requiring external bias magnetic field,

and c) self-biased non-zero magnetic field magnitude point minima. We also

introduce the Principle of Amperean Current Doubling in planar perpendicularly

magnetized thin films that can be used to improve the performance of each

permanent magnet design we present. Single conductor current-carrying designs

are suitable for single layer lithographic fabrication, as we experimentally

demonstrate. Finally, we present the case that nanometer scale recording of

perpendicular anisotropy thin magnetic films using presently available data

storage technology can provide the ultimate miniaturization of the presented

designs.

We analyze the Bogoliubov spectrum of the 3-sites Bose-Hubbard model with

finite number of Bose particles by using a semiclassical approach. The

Bogoliubov spectrum is shown to be associated with the low-energy regular

component of the classical Hubbard model. We identify the full set of the

integrals of motions of this regular component and, quantizing them, obtain the

energy levels of the quantum system. The critical values of the energy, above

which the regular Bogoliubov spectrum evolves into a chaotic spectrum, is

indicated as well.

We extract the temperature dependence of the three-body recombination rate,

observation of Efimov physics.

In addition, we obtain the atom-dimer scattering length, that may be of

Title: Spin Drag and Spin-Charge Separation in Cold Fermi Gases

Authors: Marco Polini and Giovanni Vignale

Categories: cond-mat.str-el

Comments: 4 pages, 4 figures, submitted

Subj-class: Strongly Correlated Electrons

\\

Low-energy spin and charge excitations of one-dimensional interacting

fermions are completely decoupled and propagate with different velocities.

These modes however can decay due to several possible mechanisms. In this paper

we expose a new facet of spin-charge separation: not only the speeds but also

the damping rates of spin and charge excitations are different. While the

propagation of long-wavelength charge excitations is essentially ballistic,

spin propagation is intrinsically damped and diffusive. We suggest that cold

Fermi gases trapped inside a tight atomic waveguide offer the opportunity to

measure the spin-drag relaxation rate that controls the broadening of a spin

packet.

Title: Light scattering from ultracold atoms in optical lattices as an optical

probe of quantum statistics

Authors: Igor B. Mekhov, Christoph Maschler, Helmut Ritsch

Categories: quant-ph

Comments: 15 pages, 5 figures

\\

We study off-resonant collective light scattering from ultracold atoms

trapped in an optical lattice. Scattering from different atomic quantum states

creates different quantum states of the scattered light, which can be

distinguished by measurements of the spatial intensity distribution, quadrature

variances, photon statistics, or spectral measurements. In particular,

angle-resolved intensity measurements reflect global statistics of atoms (total

number of radiating atoms) as well as local statistical quantities (single-site

statistics even without an optical access to a single site) and pair

correlations between different sites. As a striking example we consider

scattering from transversally illuminated atoms into an optical cavity mode.

For the Mott insulator state, similar to classical diffraction, the number of

photons scattered into a cavity is zero due to destructive interference, while

for the superfluid state it is nonzero and proportional to the number of atoms.

Moreover, we demonstrate that light scattering into a standing-wave cavity has

a nontrivial angle dependence, including the appearance of narrow features at

angles, where classical diffraction predicts zero.

We present a simple implementation of a density-dependent, zero-range

interactions in a degenerate Fermi gas described in hyperspherical coordinates.

The method produces a 1D effective potential which accurately describes the

ground state energy as a function of the hyperradius, the rms radius of the two

spin component gas throughout the unitarity regime. In the unitarity regime the

breathing mode frequency is found to limit to the non-interacting value. A

dynamical instability, similar to the Bosenova, is predicted to be possible in

gases containing more than three spin components, for large, negative, two-body

scattering lengths.

\\

The short-term stability of passive atomic frequency standards, especially in

pulsed operation, is often limited by local oscillator noise via

intermodulation effects. We present an experimental demonstration of the

intermodulation effect on the frequency stability of a continuous atomic

fountain clock where, under normal operating conditions, it is usually too

small to observe. To achieve this, we deliberately degrade the phase stability

of the microwave field interrogating the clock transition. We measure the

frequency stability of the locked, commercial-grade local oscillator, for two

modulation schemes of the microwave field: square-wave phase modulation and

square-wave frequency modulation. We observe a degradation of the stability

whose dependence with the modulation frequency reproduces the theoretical

predictions for the intermodulation effect. In particular no observable

degradation occurs when this frequency equals the Ramsey linewidth.

Additionally we show that, without added phase noise, the frequency instability

presently equal to 2x10-13 at 1s, is limited by atomic shot-noise and therefore

could be reduced were the atomic flux increased.

Results of theoretical calculations of ionization rates of Rb and Na Rydberg

atoms by blackbody radiation (BBR) are presented. Calculations have been

performed for nS, nP and nD states of Na and Rb, which are commonly used in a

variety of experiments, at principal quantum numbers n=8-65 and at three

ambient temperatures of 77, 300 and 600 K. A peculiarity of our calculations is

that we take into account the contributions of BBR-induced redistribution of

population between Rydberg states prior to photoionization and field ionization

by extraction electric field pulses. The obtained results show that these

phenomena affect both the magnitude of measured ionization rates and shapes of

their dependencies on n. The calculated ionization rates are compared with the

results of our earlier measurements of BBR-induced ionization rates of Na nS

and nD Rydberg states with n=8-20 at 300 K. A good agreement for all states

except nS with n>15 is observed. We also present the useful analytical formulae

for quick estimation of BBR ionization rates of Rydberg atoms.
