We report on measurements of resonantly enhanced tunneling of Bose-Einstein

condensates loaded into an optical lattice. By controlling the initial

conditions of our system we were able to observe resonant tunneling in the

ground and the first two excited states of the lattice wells. We also

investigated the effect of the intrinsic nonlinearity of the condensate on the

tunneling resonances.

Title: Bold Diagrammatic Monte Carlo: When Sign Problem is Welcome

We introduce a Monte Carlo scheme for sampling bold-line diagrammatic series

specifying an unknown function in terms of itself. The range of convergence of

this bold(-line) diagrammatic Monte Carlo (BMC) is significantly broader than

that of a simple iterative scheme for solving integral equations. With BMC

technique, a moderate "sign problem" turns out to be an advantage in terms of

the convergence of the process. For an illustrative application, we solve

one-particle s-scattering problem.

Title: On the feasibility of studying vortex noise in 2D superconductors with

cold atoms

Authors: Stefan Scheel, Rachele Fermani, and E.A. Hinds

Categories: cond-mat.other

Comments: 4 pages, 1 figure

Subj-class: Other

\\

We investigate the feasibility of using ultracold neutral atoms trapped near

a thin superconductor to study vortex noise close to the

Kosterlitz-Thouless-Berezinskii transition temperature. Alkali atoms such as

rubidium probe the magnetic field produced by the vortices. We show that the

relaxation time $T_1$ of the Zeeman sublevel populations can be conveniently

adjusted to provide long observation times. We also show that the transverse

relaxation times $T_2$ for Zeeman coherences are ideal for studying the vortex

noise. We briefly consider the motion of atom clouds held close to the surface

as a method for monitoring the vortex motion.

collision

Scattering phase shifts obtained from 87Rb Bose-gas collision experiments are

used to reconstruct effective potentials resulting, self-consistently, in the

same scattering events observed in the experiments at a particular energy. We

have found that the interaction strength close to the origin suddenly changes

from repulsion to attraction when the collision energy crosses, from below, the

l=2 shape resonance position at E = 275 mikroK. This observation may be

utilized in outlining future Bose-gas collision experiments.

thermodynamics

Comments: 5 pages, 1 figure

Subj-class: Statistical Mechanics

\\

Based on previous works, analytical methods for treating the strongly

interacting fermions ground state energy are developed through a

medium-dependent potential within the Bethe-Peierls contact interaction model.

The methods are exact in the unitary limit regime and they lead to the

self-consistent equations analogous to the Hartree ones. The rearrangement

effects on the thermodynamics due to the Hugenholtz-van Hove theorem constraint

are addressed. This theorem leads to the additional effective potential

contribution to the system physical chemical potential in order to enforce the

classical thermodynamics consistency. The generalized coupled Dyson-Schwinger

equations represent implicitly the various Bethe-Goldstone expansion diagrams.

We consider the motion of a quasi one dimensional beam of Bose-Einstein

condensed particles in a disordered region of finite extent. Interaction

effects lead to the appearance of two distinct regions of stationary flow. One

is subsonic and corresponds to superfluid motion. The other one is supersonic,

dissipative and shows Anderson localization. We compute analytically the

interaction-dependent localization length. We also explain the disappearance of

the supersonic stationary flow for large disordered samples.

gases with repulsive interactions

Categories: cond-mat.other

\\

We examine the spin asymmetry of ground states for two-dimensional,

harmonically trapped two-component gases of fermionic atoms at zero temperature

with weakly repulsive short range interactions. Our main result is that, in

contrast to the three-dimensional case, in two dimensions a non-trivial

spin-asymmetric phase can only be caused by shell structure. A simple,

qualitative description is given in terms of an approximate single particle

model, comparing well to the standard results of Hartree-Fock or direct

diagonalization methods.

It is proven that the center of mass (COM or Kohn) oscillation of a many-body

system in a harmonic trap coincides with the motion of a single particle as

long as conserving approximations are applied to treat the interactions. The

two conditions formulated by Kadanoff and Baym \cite{kb-book} are shown to be

sufficient to preserve the COM mode. The result equally applies to zero and

finite temperature, as well as to nonequilibrium situations, and to the linear

and nonlinear response regimes.

Title: Fast initialization of a high-fidelity quantum register using optical

superlattices

Authors: B. Vaucher and S. R. Clark and U. Dorner and D. Jaksch

Categories: cond-mat.other

Comments: 12 pages, 9 figures

Subj-class: Other

\\

We propose a method for the fast generation of a quantum register of

addressable qubits consisting of ultracold atoms stored in an optical lattice.

Starting with a half filled lattice we remove every second lattice barrier by

adiabatically switching on a superlattice potential which leads to a long

wavelength lattice in the Mott insulator state with unit filling. The larger

periodicity of the resulting lattice could make individual addressing of the

atoms via an external laser feasible. The dynamics of the transition from a

half filled to a commensurately filled lattice is analyzed numerically with the

help of the Time Evolving Block Decimation algorithm and analytically using the

Kibble-Zurek theory. We show that the time scale for the whole process, i.e.

creating the half filled lattice and subsequent doubling of the lattice

periodicity, is significantly faster than adiabatic direct quantum freezing of

a superfluid into a Mott insulator for large lattice periods. Our method

therefore provides a high fidelity quantum register of addressable qubits on a

fast time scale.

Interference experiments with independent condensates provide a powerful tool

for analyzing correlation functions. Scaling of the average fringe contrast

with the system size is determined by the two-point correlation function and

can be used to study the Luttinger liquid liquid behavior in one-dimensional

systems and to observe the Kosterlitz-Thouless transition in two-dimensional

quasicondensates. Additionally, higher moments of the fringe contrast can be

used to determine the higher order correlation functions. In this article we

focus on interference experiments with one-dimensional Bose liquids and show

that methods of conformal field theory can be applied to calculate the full

quantum distribution function of the fringe contrast.

Laguerre-Gaussian beams

Authors: Rina Kanamoto, Ewan M. Wright, Pierre Meystre

Categories: cond-mat.other

Comments: 10 pages, 6 figures

Subj-class: Other

\\

We investigate the quantum dynamics of Raman-coupled Bose-Einstein

condensates driven by laser beams that carry orbital angular momentum. By

adiabatically eliminating the excited atomic state we obtain an effective

two-state Hamiltonian for the coupled condensates, and quantization of the

matter-wave fields results in collapse and revivals in the quantum dynamics of

the coupled condensates. We show that the revival period depends on whether the

initial non-rotating condensate displays broken U(1) symmetry or not, and that

the difference may be detected by measuring the motion of quantized vortices

that are nested in the density profile of the Raman-coupled condensates. We

further study the steady-state population transfer using a linear sweep of the

two-photon detuning, by which the atomic population is coherently transferred

from an initial non-rotating state to the final vortex state.

filling

Authors: F. D. Klironomos, S.-W. Tsai

Categories: cond-mat.supr-con

Comments: 5 pages, 3 figures

Subj-class: Superconductivity

\\

We study a mixture of fermionic and bosonic cold atoms on a two-dimensional

optical lattice, where the fermions are prepared in two hyperfine (isospin)

states and the bosons have Bose-Einstein condensed (BEC). The coupling between

the fermionic atoms and the bosonic fluctuations of the BEC has similarities

with the electron-phonon coupling in crystals. We study the phase diagram for

this system at fixed fermion density of one per site (half-filling). We find

that tuning of the lattice parameters and interaction strengths (for

fermion-fermion, fermion-boson and boson-boson interactions) drives the system

to undergo antiferromagnetic ordering, s-wave and d-wave pairing

superconductivity or a charge density wave phase. We use functional

renormalization group analysis where retardation effects are fully taken into

account by keeping the frequency dependence of the interaction vertices and

self-energies. We calculate response functions and also provide estimates of

the energy gap associated with the dominant order, and how it depends on

different parameters of the problem.

We demonstrate the reversible mapping of a coherent state of light with mean

photon number n-bar ~= 1.1 to and from the hyperfine states of an atom trapped

within the mode of a high finesse optical cavity. The coherence of the basic

processes is verified by mapping the atomic state back onto a field state in a

way that depends on the phase of the original coherent state. Our experiment

represents an important step towards the realization of cavity QED-based

quantum networks, wherein coherent transfer of quantum states enables the

distribution of quantum information across the network.

\\

We report torsional oscillator supersolid studies of highly disordered

samples of solid $^4$He. In an attempt to approach the amorphous or glassy

state of the solid, we prepare our samples by rapid freezing from the normal

phase of liquid $^4$He. Less than two minutes is required for the entire

process of freezing and the subsequent cooling of the sample to below 1 K. The

supersolid signals observed for such samples are remarkably large, exceeding 20

% of the entire solid helium moment of inertia. These results, taken with the

finding that the magnitude of the small supersolid signals observed in our

earlier experiments can be reduced to an unobservable level by annealing,

strongly suggest that the supersolid state exists for the disordered or glassy

state of helium and is absent in high quality crystals of solid $^4$He.

We discuss the hydrodynamic boundary condition for a superfluid moving

tangentially to a rough surface. Specifically, we argue that the scattering of

quantum fluctuations off surface roughness affects the nature of the boundary

condition, and that this has important consequences including a new theorized

critical speed and the presence of normal fluid at any speed. This hydrodynamic

boundary condition is relevant not only for superfluid helium experiments but

also for experiments with trapped dilute Bose-Einstein condensates.

The regime of quantum self-confinement has been studied and a new variant of it

We study a polarized Fermi gas and demonstrate that Fano-Feshbach (FF)

resonances lead to the pairing of fermions and holes into massive bosonic modes

(bifermions and biholes), which can be viewed as signatures of a first order

quantum phase transition. These modes, which are neither conventional Cooper

pairs nor closed channel bosonic dimers, have a peculiar dispersion relation

and appear already in the weak coupling limit, i.e. for large FF detunings. Our

result is in accord with claims of Schunck \emph{et al.} [cond-mat/0702066]

that by stabilizing the normal state the population imbalance still allows

effect of s-wave fermionic pairing.

We propose a practical skim to calculate the overlap between the true ground

state of the system and a variational ansatz within a quantum Monte-Carlo

simulation. This overlap is simply related to the area under the $E(\tau)$

curve (energy as a function of imaginary time), and hence comes as a simple

byproduct of usual simulations. As a result, we find that the practical

definition of a good variational wave function for quantum Monte-Carlo

simulations, ``it converges fast to the ground state'', is equivalent to having

a good overlap with the actual ground state of the system.

The recombination of two split Bose-Einstein condensates on an atom chip is

shown to result in heating which depends on the relative phase of the two

condensates. This heating reduces the number of condensate atoms between 10 and

40% and provides a robust way to read out the phase of an atom interferometer

without the need for ballistic expansion. The heating may be caused by the

dissipation of dark solitons created during the merging of the condensates.

Bosons with non-zero spin exhibit a rich variety of superfluid and insulating

phases. Most phases support coherent spin oscillations, which have been the

focus of numerous recent experiments. These spin oscillations are Rabi

oscillations between discrete levels deep in the insulator, while deep in the

superfluid they can be oscillations in the orientation of a spinful condensate.

We describe the evolution of spin oscillations across the superfluid-insulator

quantum phase transition. For transitions with an order parameter carrying

spin, the damping of such oscillations is determined by the scaling dimension

of the composite spin operator. For transitions with a spinless order parameter

and gapped spin excitations, we demonstrate that the damping is determined by

an associated quantum impurity problem of a localized spin excitation

interacting with the bulk critical modes. We present a renormalization group

analysis of the quantum impurity problem, and discuss the relationship of our

results to experiments on ultracold atoms in optical lattices.

A low-energy effective theory for interacting bosons on a one-dimensional
