PT-symmetric extensions of the supersymmetric Korteweg-de Vries equation
Bijan Bagchi, Andreas Fring
We discuss several PT-symmetric deformations of superderivatives. Based on these various possibilities, we propose new families of complex PT-symmetric deformations of the supersym…

A generalized non-Hermitian oscillator Hamiltonian, N-fold supersymmetry and position-dependent mass models
Bijan Bagchi, Toshiaki Tanaka
A generalized non-Hermitian oscillator Hamiltonian is proposed that consists of additional linear terms which break PT-symmetry explicitly. The model is put into an equivalent Herm…
