Non-Hermitian oscillator: Construction and nonclassical properties.
Darboux transformation is an outstanding technique used to construct new exact solvable potentials in quantum mechanics, departing from one well known soluble potential. In this talk I will talk about the construction of non-Hermitian Hamiltonians whose eigenenergies are real and equidistant, even though the respective potential is complex. In order to operate in this kind of Hamiltonians the bi-orthogonality is essential, linear bi-orthogonal superpositions can be constructed, in particular coherent states, whose non-classical properties can be studied in the non-Hermitian case and in the Hermitian limit case.
