PT-symmetric potentials with imaginary asymptotic saturation

Zafar Ahmed, Sachin Kumar

We point out that PT-symmetric potentials $V_{P T} (x)$ having imaginary asymptotic saturation: $V_{P T} (x = \pm \infty) = \pm i V_{1}, V_{1} \in ℜ$ are devoid of scattering states and spe…

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…
