New Exactly Solvable Isospectral Partners for PT Symmetric Potentials
Anjana Sinha, Pinaki Roy
We examine in detail the possibilty of applying Darboux transformation to non Hermitian hamiltonians. In particular we propose a simple method of constructing exactly solvable PT s…

Quasi-exact solvability of Dirac-Pauli equation and generalized Dirac oscillators
Choon-Lin Ho, Pinaki Roy
We demonstrate that neutral Dirac particles in external electric fields, which are equivalent to generalized Dirac oscillators, are physical examples of quasi-exactly solvable syst…

Generation of exactly solvable non-Hermitian potentials with real energies
Anjana Sinha, Pinaki Roy
A series of exactly solvable non-trivial complex potentials (possessing real spectra) are generated by applying the Darboux transformation to the excited eigenstates of a non-Hermi…
