Title: Spatial distortion of trapped Fermi gases

Authors: Masudul Haque, H.T.C. Stoof

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

Comments: 4+ pages, 3 figures. Formalism for distorted trapped fermi systems +

treatment of polarized fermion experiments

Subj-class: Mesoscopic Systems and Quantum Hall Effect; Superconductivity

\\

We present a general approach for calculating densities and other local

quantities of trapped Fermi gases, when the cloud shape is distorted with

respect to the trap shape due to global energy considerations. Our approach

provides a consistent way to explore physics beyond the local density

approximation, if this is necessary due to the distortion. We illustrate this

by analyzing in detail experimentally observed distortions in an imbalanced

Fermi mixture in an elongated trap. In particular, we demonstrate in that case

dramatic deviations from ellipsoidal cloud shapes arising from the competition

between surface and bulk energies.

Title: Anomalous fermion bunching in density-density correlation

Authors: Hongwei Xiong; Shujuan Liu

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

Comments: RevTex, 4 pages

Subj-class: Other; Statistical Mechanics

\\

We consider theoretically density-density correlation of identical Fermi

system by including the finite resolution of a detector and delta-function term

omitted in the ordinary method. We find an anomalous fermion bunching effect,

which is a quantum effect having no classical analogue. This anomalous fermion

bunching is studied for ultracold Fermi gases released from a three-dimensional

optical lattices. It is found that this anomalous fermion bunching is supported

by a recent experiment (T. Rom et al Nature 444, 733 (2006)).

Title: Unconventional Transition from Superfluid to Mott Insulator Phase of

Hard-Core Bosons on the Checkerboard Lattice

Authors: Arnab Sen, Kedar Damle and T. Senthil

Categories: cond-mat.str-el

Comments: 11 pages, PRB format

Subj-class: Strongly Correlated Electrons

\\

We study hard-core bosons on the checkerboard lattice with nearest neighbour

unfrustrated hopping $t$ and `tetrahedral' plaquette charging energy $U$.

Analytical arguments and Quantum Monte Carlo simulations lead us to the

conclusion that the system undergoes a zero temperature ($T$) quantum phase

transition from a superfluid phase at small $U/t$ to a large $U/t$ Mott

insulator phase with $\rho$ = 1/4 for a range of values of the chemical

potential $\mu$. Further, the quarter-filled insulator breaks lattice

translation symmetry in a characteristic four-fold ordering pattern, and

occupies a lobe of finite extent in the $\mu$-$U/t$ phase diagram. A Quantum

Monte-Carlo study slightly away from the tip of the lobe provides evidence for

a direct weakly first-order superfluid-insulator transition. However, a

combination of indirect numerical evidence and analytical arguments leads us to

conclude that the transition {\em at} the tip of the lobe belongs to a

different landau-forbidden second-order universality class.

Title: The effects of optically induced non-Abelian gauge field in cold atoms

Authors: Li-Hua Lu and You-Quan Li

Categories: cond-mat.other cond-mat.mes-hall

Comments: Revtex 6 pages, 2 figures

Subj-class: Other; Mesoscopic Systems and Quantum Hall Effect

\\

We present a general description that $N-1$ degenerate dark states can be

generated by coupling $N$-fold degenerate ground states and a common excited

state with $N$ laser fields. Interferences between light waves with different

frequencies can produce laser fields with time-dependent amplitudes, which can

induce not only U(N) non-Abelian vector fields but also the scalar ones for the

adiabatic motion of atoms in such laser fields. As an example, a time-periodic

gauge potential is produced by applying specific laser fields to a tripod

system. Some features of the Landau levels and the ground-state phase diagram

of a rotating Bose-Einstein condensate for a concrete gauge field are also

discussed.

Title: Finite temperature phase diagram of a polarized Fermi gas in an optical

lattice

Authors: T.K. Koponen, T. Paananen, J.-P. Martikainen, and P. Torma

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

Comments: 4 pages, 3 figures

Subj-class: Superconductivity; Other

\\

We present phase diagrams for a polarized Fermi gas in an optical lattice as

a function of temperature, polarization, and lattice filling factor. We

consider the possibility of the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) phase,

Sarma or the breached pair (BP) phase, the BCS phase, the normal state, as well

as a phase separation (PS) where the BCS phase occupies one part of the volume

and the normal phase the other. We calculate the phase diagrams also at

non-zero temperatures. We show that the FFLO phase appears in a considerable

portion of the phase diagram: at zero temperature, phase separation dominates

for low polarizations, the FFLO phase appears after a critical polarization,

and the system makes a transition into a normal phase at an even higher

polarization. Phase separation ceases to exists at a certain temperature after

which the FFLO, BP, or the normal phase dominates. The phase diagrams show two

critical points of different nature. We show how various phases leave clear

signatures to the momentum distributions of the atoms which can be observed

after time of flight expansion.

Subj-class: Computational Physics; Atomic Physics

\\

We present a variational Monte Carlo (VMC) method that works equally well for

the ground and the excited states of a quantum system. The method is based on

the minimization of the variance of energy, as opposed to the energy itself in

standard methods. As a test, it is applied to the investigation of the

universal spectrum at the van der Waals length scale for two identical Bose

atoms in a symmetric harmonic trap, with results compared to the basically

exact results obtained from a multiscale quantum-defect theory.

I propose to sharpen the index h, proposed by Hirsch as a useful index to

characterize the scientific output of a researcher, by excluding the

self-citations. Performing a self-experiment and also analyzing two anonymous

data sets, it is shown that self-citations can significantly reduce the $h$

index in contrast to Hirsch's expectations.

Title: Quantum dynamics of repulsively bound atom pairs in an optical lattice

Authors: Li Wang, Yajiang Hao, Shu Chen

Categories: cond-mat.other

Comments: 5 pages, 5 figures

Subj-class: Other

\\

In this paper, we investigate the quantum dynamics of repulsively bound atom

pairs in an optical lattice described by the periodic Bose-Hubbard model by

using the exact diagonalization method. It is shown that how the dynamic

evolution of an initially confined system is affected by the on-site

interaction and the choice of the initial state. Our results are in qualitative

agreement with the corresponding experiment recently carried out in Innsbruck.

We also study the dynamics of a system in which all the particles are initially

loaded into only one optical lattice site and find that with the increasing of

the on-site interaction, the system displays a kind of self-trapping.

Title: Fractional Spin Hall Effect in Bosonic Atomic Gas

Authors: Xiong-Jun Liu, Xin Liu, L. C. Kwek and C. H. Oh

Categories: cond-mat.mes-hall

Comments: 5 pages, 1 figure

Subj-class: Mesoscopic Systems and Quantum Hall Effect

\\

We propose fractional spin hall effect (FSHE) in bosonic atomic system by

coupling the atomic spins to optical fields. The present scheme is an extension

to bosonic system of the recent work [7] on optically induced spin hall effect

in fermionic atomic system. The system has two different types of ground

states. The 1st type of ground state is a 1/3-factor Laughlin function, and has

the property of chiral - anti-chiral interchange antisymmetry, while the 2nd

type is shown to be a 1/4-factor Laughlin function with chiral - anti-chiral

symmetry. The experimental realization of the present model is also discussed.

Title: Inelastic collisions in an exactly solvable two-mode Bose-Einstein

Condensate

Authors: I. Fuentes-Schuller, P. Barberis-Blostein

Categories: quant-ph

\\

Inelastic collisions occur in Bose-Einstein condensates, in some cases,

producing particle loss in the system. Nevertheless, these processes have not

been studied in the case when particles do not escape the trap. We show that

such inelastic processes are relevant in quantum properties of the system such

as the evolution of the relative population, the self trapping effect and the

probability distribution of particles. Moreover, including inelastic terms in

the model of the two-mode condensate allows for an exact analytical solution.

Using this solution, we show that collisions favor the generation of

entanglement between the modes of the condensate as long as the collision rate

does not exceed the natural frequency of the system.

\\

We study a Mach-Zehnder interferometer fed by a coherent state in one input

port and vacuum in the other. We explore a Bayesian phase estimation strategy

to demonstrate that it is possible to achieve the standard quantum limit

independently from the true value of the phase shift and specific assumptions

on the noise of the interferometer. We have been able to implement the protocol

using parallel operation of two photon-number-resolving detectors and

multiphoton coincidence logic electronics at the output ports of a

weakly-illuminated Mach-Zehnder interferometer. This protocol is unbiased and

saturates the Cramer-Rao phase uncertainty bound and, therefore, is an optimal

phase estimation strategy.

Forces and Surface Interactions

Categories: quant-ph

Comments: 4 pages, 5 figures

\\

The strong evanescent field around ultra-thin unclad optical fibers bears a

high potential for detecting, trapping, and manipulating cold atoms.

Introducing such a fiber into a cold atom cloud, we investigate the interaction

of a small number of cold Caesium atoms with the guided fiber mode and with the

fiber surface. Using high resolution spectroscopy, we observe and analyze

light-induced dipole forces, van der Waals interaction, and a significant

enhancement of the spontaneous emission rate of the atoms. The latter can be

assigned to the modification of the vacuum modes by the fiber.

We have demonstrated Zeeman slowing and capture of neutral Ra-225 and Ra-226

atoms in a magneto-optical trap (MOT). The intercombination transition 1S0-3P1

is the only quasi-cycling transition in radium and was used for laser-cooling

and trapping. Repumping along the 3D1-1P1 transition extended the lifetime of

the trap from milliseconds to seconds. Room-temperature blackbody radiation was

demonstrated to provide repumping from the metastable 3P0 level. We measured

the isotope shift and hyperfine splittings on the 3D1-1P1 transition with the

laser-cooled atoms, and set a limit on the lifetime of the 3D1 level based on

the measured blackbody repumping rate. Laser-cooled and trapped radium is an

attractive system for studying fundamental symmetries.

Categories: quant-ph

Comments: 5 pages, 3 figures

We propose and quantitatively develop two schemes to quickly and accurately

generate a stable initial configuration of neutral atoms in optical microtraps

by extraction from the Mott insulator state in optical lattices. We show that

thousands of atoms may be extracted and stored in the ground states of optical

microtrap arrays with one atom per trap in one operational process

demonstrating massive scalability. The failure probability during extraction in

the first scheme can be made sufficiently small ($\sim 10^{-4}$)to initialize a

large scale quantum register with high fidelity. A complementary faster scheme

with more extracted atoms but lower fidelity is also developed.

Three-dimensional magnetic focusing of cold atoms with a single magnetic

impulse has been observed for the first time. We load 7x10^7 85-Rb atoms into a

magneto-optical trap, precool the atoms with optical molasses, then use moving

molasses to launch them vertically through 20.5cm to the apex of flight. In

transit the atoms are optically pumped, prior to the single magnetic lens

impulse that occurs 16.5cm above the MOT. Fluorescence images at the apex of

flight characterise the widths of the focussed cloud. Results were obtained for

four different configurations of the baseball lens, which tuned the

relationship between the axial and radial frequencies of the lens. Compact

focused clouds were seen for all four configurations.

A two-dimensional system of atoms in an anisotropic optical lattice is

studied theoretically. If the system is finite in one direction, it is shown to

exhibit a transition between a two-dimensional superfluid and a one-dimensional

Mott insulating chain of superfluid tubes. Monte Carlo simulations are

consistent with the expectation that the phase transition is of

Kosterlitz-Thouless type. The effect of the transition on experimental

time-of-flight images is discussed.

Title: Generation of EPR-entangled radiation through an atomic reservoir

Authors: Susanne Pielawa, Giovanna Morigi, David Vitali, Luiz Davidovich

Categories: quant-ph

Comments: 4 pages, 3 figures

\\

We propose a scheme for generating two-mode squeezing in high-Q resonators

using a beam of atoms with random arrival times. The scheme requires a

classical field driving transversally the atoms inside the cavity. The field

saturates the dipole transition and thereby sets it on resonance with two

non-degenerate cavity modes. The atomic beam pumps the cavity through

single-photon processes and acts like a spin reservoir, which attracts the

cavity field to the desired non-classical state, independently of the initial

state of the field. At steady state the cavity modes are in a two-mode squeezed

state, i.e., an Einstein-Podolski-Rosen (EPR) state, whose degree of

entanglement is controlled by the intensity and the frequency of the transverse

field. This scheme is robust against stochastic fluctuations in the atomic

beam, does not require atomic detection nor velocity selection, and can be

realized by presently available experimental setups with microwave resonators.

Two-dimensional images carried by optical pulses (2 ns) are delayed by up to

10 ns in a 10 cm cesium vapor cell. By interfering the delayed images with a

local oscillator, the transverse phase and amplitude profiles of the images are

shown to be preserved. It is further shown that delayed images can be well

preserved even at very low light levels, where each pulse contains on average

less than one photon.
