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…
Spin mixing induced dynamics of spinor solitons in Bose Einstein condensates
T. Panagos, A. Romero-Ros, G. C. Katsimiga +2
We explore soliton interactions in a homogeneous spinor Bose Einstein Condensate (BEC) in the presence of a magnetic field, focusing on dark bright dark and bright dark brigh…
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…
Rogue waves in extended Gross-Pitaevskii Models with a Lee-Huang-Yang correction
Sathyanarayanan Chandramouli, Simeon I. Mistakidis, Garyfallia C. Katsimiga +3
We explore the existence and dynamical generation of rogue waves (RWs) within a one dimensional quantum droplet bearing environment. RWs are computed by deploying a spacetime fixed…
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…
Observation of vector rogue waves in repulsive three-component atomic mixtures
G. A. Bougas, G. C. Katsimiga, S. Mossman +3
We report the experimental observation of vector extensions of Peregrine solitons in highly particle-imbalanced, pairwise immiscible three-component repulsive Bose-Einstein condens…
