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…
Nonlinear instability and solitons in a self-gravitating fluid
G. N. Koutsokostas, S. Sypsas, O. Evnin +2
We study a spherical, self-gravitating fluid model, which finds applications in cosmic structure formation. We argue that since the system features nonlinearity and gravity-induced…
Universal reductions and solitary waves of weakly nonlocal defocusing nonlinear Schrödinger equations
G. N. Koutsokostas, T. P. Horikis, P. G. Kevrekidis +1
We study asymptotic reductions and solitary waves of a weakly nonlocal defocusing nonlinear Schrödinger (NLS) model. The hydrodynamic form of the latter is analyzed by means of mul…
