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…
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…
NLS approximation and dark solitons for the Adlam-Allen model of cold collisionless plasmas
George P. Veldes, Vassilis Koukouloyannis, Dimitrios J. Frantzeskakis +1
The present work extends earlier considerations on a quintessential model of cold, collisionless plasmas, namely the Adlam-Allen model. Previously, an analysis of homoclinic soluti…
Harnessing Nonlinearity to Tame Wave Dynamics in Nonreciprocal Active Systems
Sayan Jana, Bertin Many Manda, Vassos Achilleos +2
We present a mechanism to generate unidirectional pulse-shaped propagating waves, tamed to exponential growth and dispersion, in active systems with nonreciprocal and nonlinear cou…
