Density matrices and entropy operator for non-Hermitian quantum mechanics
Fabio Bagarello, Francesco Gargano, Lidia Saluto
In this paper we consider density matrices operator related to non-Hermitian Hamiltonians. In particular, we analyse two natural extensions of what is usually called a density matr…

Extended coupled SUSY, pseudo-bosons and weak squeezed states
F Bagarello, F. Gargano, L. Saluto
In this paper we consider squares of pseudo-bosonic ladder operators and we use them to produce explicit examples of eigenstates of certain operators satisfying a deformed $\mathfr…
