Temperature-induced decay of persistent currents in a superfluid ultracold gas

A Kumar, S Eckel, F Jendrzejewski, GK Campbell - Physical Review A, 2017 - APS
We study how temperature affects the lifetime of a quantized, persistent current state in a
toroidal Bose-Einstein condensate. When the temperature is increased, we find a decrease …

Stability and dispersion relations of three-dimensional solitary waves in trapped Bose–Einstein condensates

AM Mateo, J Brand - New Journal of Physics, 2015 - iopscience.iop.org
We analyse the dynamical properties of three-dimensional solitary waves in cylindrically
trapped Bose–Einstein condensates. Families of solitary waves bifurcate from the planar …

Kink correlations, domain-size distribution, and emptiness formation probability after a Kibble-Zurek quench in the quantum Ising chain

J Dziarmaga, MM Rams - Physical Review B, 2022 - APS
Linear quench of the transverse field drives the quantum Ising chain across a quantum
