Shapiro steps in driven atomic Josephson junctions
Vijay Pal Singh, Juan Polo, Ludwig Mathey +1
We study driven atomic Josephson junctions realized by coupling two two-dimensional atomic clouds with a tunneling barrier. By moving the barrier at a constant velocity, dc and ac…
Thermal suppression of demixing dynamics in a binary condensate
Vijay Pal Singh, Luigi Amico, Ludwig Mathey
We investigate the demixing dynamics in a binary two-dimensional (2D) Bose superfluid using classical-field dynamics. By quenching the interspecies interaction parameter, we identi…
Universal Scaling of the Dynamic BKT Transition in Quenched 2D Bose Gases
Shinichi Sunami, Vijay P. Singh, David Garrick +6
While renormalization group theory is a fully established method to capture equilibrium phase transitions, the applicability of RG theory to universal non-equilibrium behavior rema…
Condensate formation in a dark state of a driven atom-cavity system
Jim Skulte, Phatthamon Kongkhambut, Sahana Rao +4
We demonstrate condensate formation in a dark state in an ultracold quantum gas coupled to a high-finesse cavity and pumped by a shaken optical lattice. We show experimentally and…
Implementation of an atomtronic SQUID in a strongly confined toroidal condensate
Hannes Kiehn, Vijay Pal Singh, Ludwig Mathey
We investigate the dynamics of an atomtronic SQUID created by two mobile barriers, moving at two different, constant velocities in a quasi-1D toroidal condensate. We implement a mu…
First and second sound in a dilute Bose gas across the BKT transition
Vijay Pal Singh, Ludwig Mathey
We study the propagation of the two sound modes in two-dimensional Bose gases across the Berezinksii-Kosterlitz-Thouless (BKT) transition using classical-field dynamics, which is m…
