Periodic quenches across the Berezinskii-Kosterlitz-Thouless phase transition
Kate Brown, Thomas Bland, Paolo Comaron +1
The quenched dynamics of an ultracold homogeneous atomic two-dimensional Bose gas subjected to periodic quenches across the Berezinskii-Kosterlitz-Thouless (BKT) phase transition a…
Crossover in the dynamical critical exponent of a quenched two-dimensional Bose gas
Andrew J. Groszek, Paolo Comaron, Nikolaos P. Proukakis +1
We study the phase ordering dynamics of a uniform Bose gas in two dimensions following a quench into the ordered phase. We explore the crossover between dissipative and conservativ…
Persistent current formation in double-ring geometries
Thomas Bland, Quentin Marolleau, Paolo Comaron +2
Quenching an ultracold bosonic gas in a ring across the Bose-Einstein condensation phase transition is known, and has been experimentally observed, to lead to the spontaneous emerg…
Quench dynamics of an ultracold two-dimensional Bose gas
Paolo Comaron, Fabrizio Larcher, Franco Dalfovo +1
We study the dynamics of a two-dimensional Bose gas after an instantaneous quench of an initially ultracold thermal atomic gas across the Berezinskii-Kosterlitz-Thouless phase tran…
