Abstract

Using the method of point canonical transformation, we derive some exactly solvable rationally extended quantum Hamiltonians which are non-Hermitian in nature and whose bound state wave functions are associated with Laguerre- or Jacobi-type X1X_1 exceptional orthogonal polynomials. These Hamiltonians are shown, with the help of imaginary shift of co-ordinate: eαpxeαp=x+iα e^{-\alpha p} x e^{\alpha p} = x+ i \alpha , to be both quasi and pseudo-Hermitian. It turns out that the corresponding energy spectra is entirely real.
