## Real discrete spectrum in complex non-PT-symmetric Scarf II potential

Zafar Ahmed, Amal Nathan Joseph

Hitherto, it is well known that complex PT-symmetric Scarf II has real discrete spectrum in the parametric domain of unbroken PT-symmetry. We reveal new interesting complex, non-PT-symmetric parametric domains of this versatile potential, $$V(x)$$, where the spectrum is again discrete and real. Showing that the Hamiltonian, $$p^2/2m+V(x)$$, is pseudo-Hermitian could be challenging, if possible.
