Families of stable solitons and excitations in the PT-symmetric nonlinear Schrödinger equations with position-dependent effective masses
Since the parity-time-([Formula: see text] -) symmetric quantum mechanics was put forward, fundamental properties of some linear and nonlinear models with [Formula: see text] -symmetric potentials have been investigated. However, previous studies of [Formula: see text] -symmetric waves were limited...
