The following message was sent to the matts_arxiv list by Matthew Davis <mdavis_at_physics.uq.edu.au>

Hi all,

I'm going to take this opportunity to let you know about a workshop that may be

of interest:

"International Workshop on Quantum Noise" - celebrating Crispin Gardiner's

contributions to Quantum Optics and Atom Optics

14 - 18 MAY 2007

BreakFree Grand Pacific resort, Caloundra, Queensland, Australia.

The workshop will cover hot topics in quantum optics and ultracold quantum

gases, from both theory and experiment. A particular focus will be on quantum

aspects of matter waves and macroscopic quantum states, going beyond the methods

and predictions of mean-field theory. This will include advances in analytical

and computational methods, the latest experimental results probing the quantum

nature of BECs, and applications of BEC to quantum information.

Invited speakers: Brian Anderson, Rob Ballagh, Howard Carmichael, Subhash

Chaturvedi, Crispin Gardiner, Ed Hinds, Gerd Leuchs, Scott Parkins, Silvania

Pereira (tbc), Chris Westbrook, Peter Zoller (tbc)

There is a poster on the website if you wouldn't mind advertising it...

Not so many abstracts this week, only 16:

Title: Time-Averaged Adiabatic Potentials: Versatile traps and waveguides for

ultracold quantum gases

Authors: Igor Lesanovsky and Wolf von Klitzing

Comments: 5 pages, 3 figures

Subj-class: Other

\\

We demonstrate a novel class of trapping potentials, time-averaged adiabatic

potentials (TAAP) which allows the generation of a large variety of traps and

waveguides for ultracold atoms. Multiple traps can be coupled through

controllable tunneling barriers or merged altogether. We present analytical

expressions for pancake-, cigar-, and ring- shaped traps. The ring-geometry is

of particular interest for guided matter-wave interferometry as it provides a

perfectly smooth waveguide of controllable diameter, and thus a tunable

sensitivity of the interferometer.

Title: Dark soliton dynamics in Bose-Einstein condensates at finite temperature

Authors: B. Jackson, N. P. Proukakis, and C. F. Barenghi

Comments: 4 pages, 4 figures

Subj-class: Statistical Mechanics

\\

The dynamics of a dark soliton in an elongated Bose-Einstein condensate at

finite temperatures is studied using numerical simulations. We find that in the

presence of harmonic confinement the soliton may oscillate even at finite

temperatures, but with an amplitude that increases with time, indicating the

decay of the soliton. The timescale of this decay decreases both with

increasing temperature and with increasing initial soliton velocity.

Simulations performed for the experiment of S. Burger et al., Phys. Rev. Lett.

83, 5198 (1999), reveal excellent agreement with the observed soliton decay,

confirming the crucial role of the thermal cloud in soliton dynamics.

Title: Mesoscopic entanglement of atomic ensembles through non-resonant

stimulated Raman scattering

Authors: Wenhai Ji, Chunbai Wu, S.J. van Enk, M.G. Raymer

Comments: 32 papges, 6 figures and 1 table

\\

We propose a scheme of generating and verifying mesoscopic-level entanglement

between two atomic ensembles using non-resonant stimulated Raman scattering.

Entanglement can be generated by direct detection or balanced homodyne

detection of the Stokes fields from the two cells, after they interfere on a

beam splitter. The entanglement of the collective atomic fields can be

transferred to the anti-Stokes fields in a readout process. By measuring the

operator moments of the anti-Stokes fields, we can verify the presence of

entanglement. We model the effects of practical factors such as Stokes field

detector quantum efficiency and additive thermal noise in the entanglement

generating process, and anti-Stokes field losses in the entanglement

verification process, and find achievable regimes in which entanglement can be

verified at the levels of tens to hundreds of atomic excitations in the

ensembles.

Dark state cooling of atoms within a Bloch band of an optical lattice

Categories: cond-mat

\\

We analyse a laser assisted sympathetic cooling scheme for atoms within the

lowest Bloch band of an optical lattice. This scheme borrows ideas from

sub-recoil laser cooling, implementing them in a new context in which the atoms

in the lattice are coupled to a BEC reservoir. In this scheme, excitation of

atoms between Bloch bands replaces the internal structure of atoms in normal

laser cooling, and spontaneous emission of photons is replaced by creation of

excitations in the BEC reservoir. We analyse the cooling process for many

bosons and fermions, and obtain possible temperatures corresponding to a small

fraction of the Bloch band width within our model. This system can be seen as a

novel realisation of a many-body open quantum system.

\\

We present a pairing fluctuation theory which self-consistently incorporates

finite momentum pair excitations in the context of BCS--Bose-Einstein

condensation (BEC) crossover, and we apply this theory to superfluidity in high

$T_c$ superconductors and ultracold Fermi gases. There are strong similarities

between Fermi gases in the unitary regime and high Tc superconductors. We

address key issues of common interest in both systems, e.g., the pseudogap,

although we focus more on the Fermi gases and recent experiments, e.g., the

phase diagram, evidence for a pseudogap, thermodynamic behavior, and effects of

population imbalance.

Title: Ultracold Neutral Plasmas

Authors: T. C. Killian, T. Pattard, T. Pohl and J. M. Rost

Comments: 89 pages, 54 images

Report-no: KL-06-01

Subj-class: Atomic Physics; Plasma Physics

\\

Ultracold neutral plasmas, formed by photoionizing laser-cooled atoms near

the ionization threshold, have electron temperatures in the 1-1000 kelvin range

and ion temperatures from tens of millikelvin to a few kelvin. They represent a

new frontier in the study of neutral plasmas, which traditionally deals with

much hotter systems, but they also blur the boundaries of plasma, atomic,

condensed matter, and low temperature physics. Modelling these plasmas

challenges computational techniques and theories of non-equilibrium systems, so

the field has attracted great interest from the theoretical and computational

physics communities. By varying laser intensities and wavelengths it is

possible to accurately set the initial plasma density and energy, and

charged-particle-detection and optical diagnostics allow precise measurements

for comparison with theoretical predictions. Recent experiments using optical

probes demonstrated that ions in the plasma equilibrate in a strongly coupled

fluid phase. Strongly coupled plasmas, in which the electrical interaction

energy between charged particles exceeds the average kinetic energy, reverse

the traditional energy hierarchy underlying basic plasma concepts such as Debye

screening and hydrodynamics. Equilibration in this regime is of particular

interest because it involves the establishment of spatial correlations between

particles, and it connects to the physics of the interiors of gas-giant planets

and inertial confinement fusion devices.

Authors: V. A. Kuz'menko

Comments: 3 pages LaTeX2e, 1 figure

Subj-class: Optics; General Physics

\\

Physical explanation of the origin of quantum resonances in a periodically

kicked Bose-Einstein condensate is proposed. It is based on the assumption of

inequality of the differential cross-sections of forward and partially reversed

optical transitions. For quantitative determination of such differences, we

propose to study the Bloch oscillations in a vertical optical lattice with

short pulses of laser radiation.

\\

Fifty years ago, Hanbury Brown and Twiss (HBT) discovered photon bunching in

light emitted by a chaotic source, highlighting the importance of two-photon

correlations and stimulating the development of modern quantum optics . The

quantum interpretation of bunching relies upon the constructive interference

between amplitudes involving two indistinguishable photons, and its additive

character is intimately linked to the Bose nature of photons. Advances in atom

cooling and detection have led to the observation and full characterisation of

the atomic analogue of the HBT effect with bosonic atoms. By contrast, fermions

should reveal an antibunching effect, i.e., a tendency to avoid each other.

Antibunching of fermions is associated with destructive two-particle

interference and is related to the Pauli principle forbidding more than one

identical fermion to occupy the same quantum state. Here we report an

experimental comparison of the fermion and the boson HBT effects realised in

the same apparatus with two different isotopes of helium, 3He (a fermion) and

4He (a boson). Ordinary attractive or repulsive interactions between atoms are

negligible, and the contrasting bunching and antibunching behaviours can be

fully attributed to the different quantum statistics. Our result shows how

atom-atom correlation measurements can be used not only for revealing details

in the spatial density, or momentum correlations in an atomic ensemble, but

also to directly observe phase effects linked to the quantum statistics in a

many body system. It may thus find applications to study more exotic situations

clocks

Authors: K. Szymaniec, W. Chalupczak, E. Tiesinga, C.J. Williams, S. Weyers, R.

Wynands

Categories: physics.atom-ph

Subj-class: Atomic Physics

\\

We have observed that the collisional frequency shift in primary caesium

fountain clocks varies with the clock state population composition and, in

particular, is zero for a given fraction of the |F = 4, mF = 0> atoms,

depending on the initial cloud parameters. We present a theoretical model

explaining our observations. The possibility of the collisional shift

cancellation implies an improvement in the performance of caesium fountain

standards and a simplification in their operation. Our results also have

implications for test operation of fountains at multiple pi/2 pulse areas.

We theoretically study the observable response of edge currents in two

mean-field theory to relate persistent edge currents surrounding a Mott

measurements. As an application, we briefly discuss the detection of Chern

number using edge currents of a topologically ordered optical lattice

insulator.

We describe two-photon photoassociation (PA) experiments operated in an

ultracold gas of metastable $^4$He$^*$ atoms in the $2^3S_1$ state.

Atom-molecule dark resonances as well as Raman signals provide information on

the exotic molecule in the least bound vibrational J=2, $v=14$ state of the

$^5\Sigma_g^+$ interaction potential of two spin-polarized metastable atoms.

The physical origin of the various two-photon PA signals is first discussed.

Their linewidths are interpreted in term of processes limiting the lifetime

$\tau$ of the exotic molecule. A value of $\tau=1.4\pm0.3 \mu$s is found, which

is discussed in view of two recent calculations of the Penning ionization rate

induced by spin-dipole coupling and of the atom-molecule inelastic collisions.

We experimentally and theoretically study the continuous accumulation of cold

atoms from a magneto-optical trap (MOT) into a finite depth trap, consisting in

a magnetic quadrupole trap dressed by a radiofrequency (RF) field. Chromium

atoms (52 isotope) in a MOT are continuously optically pumped by the MOT lasers

to metastable dark states. In presence of a RF field, the temperature of the

metastable atoms that remain magnetically trapped can be as low as 25 microK,

with a density of 10^17 atoms.m-3, resulting in an increase of the phase-space

density, still limited to 7.10^-6 by inelastic collisions. To investigate the

thermalization issues in the truncated trap, we measure the free evaporation

rate in the RF-truncated magnetic trap, and deduce the average elastic cross

section for atoms in the 5D4 metastable states, equal to 7.0 10^-16m2.

\\

We examine the lowest excitations of one-dimensional few-boson systems

trapped in double wells of variable barrier height. Based on a numerically

exact multi-configurational method, we follow the whole pathway from the

non-interacting to the fermionization limit. It is shown how, in a purely

harmonic trap, the initially equidistant, degenerate levels are split up due to

interactions, but merge again for strong enough coupling. In a double well, the

low-lying spectrum is largely rearranged in the course of fermionization,

exhibiting level adhesion and (anti-)crossings. The evolution of the underlying

states is explained in analogy to the ground-state behavior. Our discussion is

complemented by illuminating the crossover from a single to a double well.

Title: Coupling of hydrodynamics and quasiparticle motion in collective modes

Authors: Michael Urban (IPNO)

Categories: cond-mat.other

Comments: 14 pages

Proxy: ccsd in2p3-00120317

Subj-class: Other

\\

At finite temperature, the hydrodynamic collective modes of superfluid

trapped Fermi gases are coupled to the motion of the normal component, which in

the BCS limit behaves like a collisionless normal Fermi gas. The coupling

between the superfluid and the normal components is treated in the framework of

a semiclassical transport theory for the quasiparticle distribution function,

combined with a hydrodynamic equation for the collective motion of the

superfluid component. We develop a numerical test-particle method for solving

these equations in the linear response regime. As a first application we study

the temperature dependence of the collective quadrupole mode of a Fermi gas in

a spherical trap. The coupling between the superfluid collective motion and the

quasiparticles leads to a rather strong damping of the hydrodynamic mode

already at very low temperatures. At higher temperatures the spectrum has a

two-peak structure, the second peak corresponding to the quadrupole mode in the

normal phase.

Categories: cond-mat.other

\\

We study the possibility of implementing a quantum switch and a quantum

memory for matter wave lattice solitons by making them interact with

"effective" potentials (barrier/well) corresponding to defects of the optical

lattice. In the case of interaction with an "effective" potential barrier, the

bright lattice soliton experiences an abrupt transition from complete

transmission to complete reflection (quantum switch) for a critical height of

the barrier. The trapping of the soliton in an "effective" potential well and

its release on demand, without loses, shows the feasibility of using the system

as a quantum memory. The inclusion of defects as a way of controlling the

interactions between two solitons is also reported.

We analyze the formation of Rb_2 molecules with short photoassociation pulses

applied to a cold Rb-85 sample. The laser field couples a continuum level of

the ground electronic state X ^1 Sigma_g^+ with bound levels in the

0_u^+(5S+5P_{1/2}) and 0_u^+(5S+5P_{3/2}) vibrational series. The non-adiabatic

coupling between the two excited channels induces time-dependent beatings in

the populations. We propose to take advantage of these oscillations either to

probe the photoassociation process via a photoionization pulse, or to optimize

the stabilization step into deep levels of the ground state.
