Experimental and numerical observation of dark and bright discrete solitons in the band-gap of a diatomic-like electrical lattice
F. Palmero, L. Q. English, Xuan-Lin Chen +3
We observe dark and bright intrinsic localized modes (ILMs) or discrete breathers (DB) experimentally and numerically in a diatomic-like electrical lattice. The generation of dark…
Continuous families of solitary waves in non-symmetric complex potentials: A Melnikov theory approach
Yannis Kominis, Jesus Cuevas-Maraver, Panayotis G. Kevrekidis +2
The existence of stationary solitary waves in symmetric and non-symmetric complex potentials is studied by means of Melnikov's perturbation method. The latter provides analytical c…
Speed-of-light pulses in a nonlinear Weyl equation
J. Cuevas-Maraver, P. G. Kevrekidis, F. G. Mertens +1
We introduce a prototypical nonlinear Weyl equation, motivated by recent developments in massless Dirac fermions, topological semimetals and photonics. We study the dynamics of its…
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…
Nonlinear Beam Propagation in a Class of Complex Non-PT -Symmetric Potentials
J. Cuevas-Maraver, P. G. Kevrekidis, D. J. Frantzeskakis +1
The subject of PT-symmetry and its areas of application have been blossoming over the past decade. Here, we consider a nonlinear Schrödinger model with a complex potential that can…
