Nonlinear Anti-(Parity-Time) symmetric dimer
A. S. Rodrigues, R. M. Ross, V. V. Konotop +2
In the present work we propose a nonlinear anti--symmetric dimer, that at the linear level has been experimentally created in the realm of electric circuit resonators…
Hydrodynamics and two-dimensional dark lump solitons for polariton superfluids
D. J. Frantzeskakis, T. P. Horikis, A. S. Rodrigues +3
We study a two-dimensional incoherently pumped exciton-polariton condensate described by an open-dissipative Gross-Pitaevskii equation for the polariton dynamics coupled to a rate…
N-break states in a chain of nonlinear oscillators
A. S. Rodrigues, P. G. Kevrekidis, M. Dobson
In the present work we explore a pre-stretched oscillator chain where the nodes interact via a pairwise Lennard-Jones potential. In addition to a homogeneous solution, we identify…
A Korteweg-de Vries description of dark solitons in polariton superfluids
R. Carretero-González, J. Cuevas-Maraver, D. J. Frantzeskakis +3
We study the dynamics of dark solitons in an incoherently pumped exciton-polariton condensate by means of a system composed by a generalized open-dissipative Gross-Pitaevskii equat…
Interactions and scattering of quantum vortices in a polariton fluid
Lorenzo Dominici, R. Carretero-Gonzalez, Jesus Cuevas-Maraver +9
Quantum vortices, the quantized version of classical vortices, play a prominent role in superfluid and superconductor phase transitions. However, their exploration at a particle le…
From Nodeless Clouds and Vortices to Gray Rings and Symmetry-Broken States in Two-Dimensional Polariton Condensates
A. S. Rodrigues, P. G. Kevrekidis, R. Carretero-González +3
We consider the existence, stability and dynamics of the nodeless state and fundamental nonlinear excitations, such as vortices, for a quasi-two-dimensional polariton condensate in…
