Weak pseudo-Hermiticity and antilinear commutant
Weak pseudo-Hermiticity and antilinear commutant
We inquire into some properties of diagonalizable pseudo-Hermitian operators, showing that their definition can be relaxed and that the pseudo-Hermiticity property is strictly connected with the existence of an antilinear symmetry. This result is then illustrated by considering the particular case of the complex Morse potential.
