PT-Symmetric dimer in a generalized model of coupled nonlinear oscillators
J. Cuevas-Maraver, A. Khare, P. G. Kevrekidis +2
In the present work, we explore the case of a general PT-symmetric dimer in the context of two both linearly and nonlinearly coupled cubic oscillators. To obtain an analytical hand…

Stability of solitary waves in the nonlinear Dirac equation with arbitrary nonlinearity
Sihong Shao, Niurka R. Quintero, Franz G. Mertens +3
We consider the nonlinear Dirac equation in 1+1 dimension with scalar-scalar self interaction and with mass . Using the exact analytic form…

Periodic and Hyperbolic Soliton Solutions of a Number of Nonlocal PT-Symmetric Nonlinear Equations
Avinash Khare, Avadh Saxena
For a number of nonlocal nonlinear equations such as nonlocal, nonlinear Schrödinger equation (NLSE), nonlocal Ablowitz-Ladik (AL), nonlocal, saturable discrete NLSE (DNLSE), coupl…
