Three types of discrete energy eigenvalues in complex PT-symmetric scattering potentials

Zafar Ahmed, Sachin Kumar, Dona Ghosh

For complex PT-symmetric scattering potentials (CPTSSPs) $V (x) = V_{1} f_{e v e n} (x) + i V_{2} f_{o dd} (x), f_{e v e n} (\pm \infty) = 0 = f_{o dd} (\pm \infty), V_{1}, V_{2} \in ℜ$ , we show that c…

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 $H = - d^{2} / d x^{2} + V (x)$ . For smaller va…
