Bose–Einstein condensation on curved manifolds
New Journal of Physics, 2020 Here we describe a weakly interacting Bose gas on a curved smooth manifold, which is embedded in the three-dimensional Euclidean space. To this end we start by considering a harmonic trap in the normal direction of the manifold, which confines the three ...

Conformal Field Theory for Inhomogeneous One-dimensional Quantum Systems: the Example of Non-Interacting Fermi Gases [PDF]
, 2016 Conformal field theory (CFT) has been extremely successful in describing large-scale universal effects in one-dimensional (1D) systems at quantum critical points. Unfortunately, its applicability in condensed matter physics has been limited to situations

Prethermalization in coupled one-dimensional quantum gases
SciPost PhysicsWe consider the problem of the development of steady states in one-dimensional Bose gas tubes that are weakly coupled to one another through a density-density interaction. We analyze this development through a Boltzmann collision integral approach.

Communications Physics, 2022 Quantum fluctuations stabilize dense self-bound macroscopic quantum states in quantum gases. This work places an Erbium dipolar ultracold atomic gas with dominantly attractive long-range interactions in a 1D periodic lattice, and uses interferometric ...

A Dynamical Self-Consistent Finite Temperature Kinetic Theory: The ZNG Scheme
, 2012 We review a self-consistent scheme for modelling trapped weakly-interacting quantum gases at temperatures where the condensate coexists with a significant thermal cloud. This method has been applied to atomic gases by Zaremba, Nikuni, and Griffin, and is

Multiphoton interband excitations of quantum gases in driven optical lattices [PDF]
, 2015 We report on the observation of multiphoton interband absorption processes for quantum gases in shaken light crystals. Periodic inertial forcing, induced by a spatial motion of the lattice potential, drives multiphoton interband excitations of up to the ...

Effective Control of Chemical Potentials by Rabi Coupling with RF-Fields in Ultracold Mixtures
Condensed Matter, 2018 We show that a linear term coupling the atoms of an ultracold binary mixture provides a simple method to induce an effective and tunable population imbalance between them.
