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…

Divergence of $⟨ p^{6} ⟩$ in discontinuous potential wells

Zafar Ahmed, Sachin Kumar, Dona Ghosh +1

The surprising divergence of the expectation value $< p^{6} >$ for the square well potential is known. Here, we prove and demonstrate the divergence of $< p^{6} >$ in potential wel…

Expectation values of $p^{2}$ and $p^{4}$ in the square well potential

Zafar Ahmed, Dona Ghosh, Sachin Kumar +1

Position and momentum representations of a wavefunction $ψ (x)$ and $ϕ (p)$ , respectively are physically equivalent yet mathematically in a given case one may be easier or more trans…
