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…
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.…
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…
Stability and mixed phases of three-component droplets in one dimension
I. A. Englezos, E. G. Charalampidis, P. Schmelcher +1
We explore the ground state properties and excitation spectra of one-dimensional three-component bosonic mixtures accommodating a droplet in two of the species and a third minority…
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…
Pattern formation in ring condensates subjected to bichromatic driving
Premabrata Manna, S. I. Mistakidis, P. G. Kevrekidis +1
We investigate the dynamical formation of nonlinear patterns in one-dimensional ring condensates under bichromatic periodic modulation of the interaction strength. The stability ph…
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…
Localization and splitting of a quantum droplet with a potential defect
F. Bristy, G. A. Bougas, G. C. Katsimiga +1
We unravel the existence and nonequilibrium response of one-dimensional harmonically trapped droplet configurations in the presence of a central potential barrier or well. For fixe…
Energy spectra and fluxes of two-dimensional turbulent quantum droplets
Shawan Kumar Jha, Mahendra K. Verma, S. I. Mistakidis +1
We explore the energy spectra and associated fluxes of turbulent two-dimensional quantum droplets subjected to a rotating paddling potential which is removed after a few oscillatio…
Interaction imbalanced spin-orbit coupled quantum droplets
Sonali Gangwar, Rajamanickam Ravisankar, S. I. Mistakidis +2
We explore the ground states and quench dynamics of one-dimensional quantum droplets with spin-orbit coupling (SOC) and an imbalance in intracomponent interactions. A plethora of m…
Density effects on the interferometry of Efimov states by modulating magnetic fields
G. Bougas, S. I. Mistakidis, P. Giannakeas
Dynamical association of Efimov trimers in thermal gases by means of modulated magnetic fields has proven very fruitful in determining the binding energy of trimers. The latter was…
