Real discrete spectrum of complex PT-symmetric scattering potentials
Zafar Ahmed, Joseph Amal Nathan, Dhruv Sharma +1
We investigate the parametric evolution of the real discrete spectrum of several complex PT symmetric scattering potentials of the type $V(x)=-V_1 F_e(x) + i V_2 F_o(x), V_1>0, F_e…

Accidental crossings of eigenvalues in one-dimensional complex PT-symmetric Scarf-II potential
Zafar Ahmed, Dona Ghosh, Joseph Amal Nathan +1
So far, the well known two branches of real discrete spectrum of complex PT-symmetric Scarf II potential are kept isolated. Here, we suggest that these two need to be brought toget…

A new solvable complex PT-symmetric potential
Zafar Ahmed, Dona Ghosh, Joseph Amal Nathan
We propose a new solvable one-dimensional complex PT-symmetric potential as $V(x)= ig~ \mbox{sgn}(x)~ |1-\exp(2|x|/a)|$ and study the spectrum of . For smaller va…
