Dynamics and statistical mechanics of ultra-cold Bose gases using c-field techniques

PB Blakie, AS Bradley, MJ Davis, RJ Ballagh… - Advances in …, 2008 - Taylor & Francis
We review phase-space techniques based on the Wigner representation that provide an
approximate description of dilute ultra-cold Bose gases. In this approach the quantum field …

Bose-Einstein condensates in spin-orbit-coupled optical lattices: Flat bands and superfluidity

Y Zhang, C Zhang - Physical Review A—Atomic, Molecular, and Optical …, 2013 - APS
Recently spin-orbit (SO)-coupled superfluids in free space or harmonic traps have been
extensively studied, motivated by the recent experimental realization of SO coupling for …

Nonlinear phenomena of ultracold atomic gases in optical lattices: Emergence of novel features in extended states

G Watanabe, BP Venkatesh, R Dasgupta - Entropy, 2016 - mdpi.com
The system of a cold atomic gas in an optical lattice is governed by two factors: nonlinearity
originating from the interparticle interaction, and the periodicity of the system set by the …

Decay of a superfluid current of ultracold atoms in a toroidal trap

AC Mathey, CW Clark, L Mathey - Physical Review A, 2014 - APS

Superflow decay in a toroidal Bose gas: The effect of quantum and thermal fluctuations

Z Mehdi, A Bradley, J Hope, S Szigeti - SciPost Physics, 2021 - scipost.org
We theoretically investigate the stochastic decay of persistent currents in a toroidal ultracold
atomic superfluid caused by a perturbing barrier. Specifically, we perform detailed three …

We study experimentally the stability of excited, interacting states of bosons in a double-well
optical lattice in regimes where the nonlinear interactions are expected to induce …

Long time universality of black-hole lasers

JRM De Nova, PF Palacios, I Carusotto… - New Journal of …, 2021 - iopscience.iop.org
For flowing quantum gases, it has been found that at long times an initial black-hole laser
(BHL) configuration exhibits only two possible states: the ground state or a periodic self …

Phase-space mixing in dynamically unstable, integrable few-mode quantum systems

R Mathew, E Tiesinga - Physical Review A, 2017 - APS
Quenches in isolated quantum systems are currently a subject of intense study. Here, we
