Solitary waves in the coupled nonlinear massive Thirring as well as coupled Soler models with arbitrary nonlinearity

Avinash Khare, Fred Cooper, John F. Dawson +2

Motivated by the recent introduction of an integrable coupled massive Thirring model by Basu-Mallick et al, we introduce a new coupled Soler model. Further we generalize both the c…

Stability of exact solutions of the $(2 + 1)$ -dimensional nonlinear Schrödinger equation with arbitrary nonlinearity parameter $κ$

Fred Cooper, Avinash Khare, Efstathios G. Charalampidis +2

In this work, we consider the nonlinear Schrödinger equation (NLSE) in $2 + 1$ dimensions with arbitrary nonlinearity exponent $κ$ in the presence of an external confining potential.…
