Faraday pattern formation in dipolar superfluid and supersolid quantum gases
Sumit Semwal, Shawan K. Jha, G. A. Bougas +2
We investigate Faraday instabilities in three-dimensional parametrically driven trapped dipolar quantum gases within the framework of the extended Gross-Pitaevskii equation. In the…
Correlated many-body quantum dynamics of the Peregrine soliton
D. Diplaris, G. A. Bougas, P. G. Kevrekidis +3
We explore the correlated dynamics underlying the formation of the quantum Peregrine soliton, a prototypical rogue-wave excitation, utilizing interaction quenches from repulsive to…
Signatures of rigidity and second sound in dipolar supersolids
G. A. Bougas, T. Bland, H. R. Sadeghpour +1
We propose a dynamical protocol to probe the rigidity and phase coherence of dipolar supersolids by merging initially separated fragments in quasi-one-dimensional (1D) double-well…
Generation of dipolar supersolids through a barrier sweep in droplet lattices
E. L. Brakensiek, G. A. Bougas, S. I. Mistakidis
We propose a dynamical protocol to generate supersolids in dipolar quantum gases by sweeping a repulsive Gaussian barrier through an incoherent quasi-one-dimensional droplet array.…
Extreme (Rogue) Waves: From Theory to Experiments in Ultracold Gases and Beyond
A. Chabchoub, P. Engels, P. G. Kevrekidis +4
In this Chapter, we review key theoretical and experimental advances in the study of extreme nonlinear wave events, called rogue waves (RWs), in both single-component attractively…
First-order phase transition in atom-molecule quantum degenerate mixtures with coherent three-body recombination
G. A. Bougas, A. Vardi, H. R. Sadeghpour +2
We map the phase diagram of a two-mode atom-molecule Bose-Einstein condensate with Fano-Feshbach and coherent three-body recombination (cTBR) terms. The standard second order phase…
