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…
Two-dimensional solitons in extended GPE models with Lee-Huang-Yang corrections
G. N. Koutsokostas, F. Bristy, E. C. Psychogiou +5
We investigate the existence and dynamics of two-dimensional solitary waves in a quantum droplet environment described by the extended Gross-Pitaevskii equation featuring logarithm…
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.…
Generation of wave turbulence in dipolar gases driven across their phase transitions
G. A. Bougas, K. Mukherjee, S. I. Mistakidis
Ultracold quantum gases with long-range anisotropic interactions host novel exotic phases of matter, such as supersolids, exhibiting both rigid and superfluid characteristics. The…
