Some classes of finite-dimensional ladder operators
Fabio Bagarello, Antonino Faddetta, Francesco Oliveri
We introduce and study some special classes of ladder operators in finite-dimensional Hilbert spaces. In particular we consider a truncated version of quons, their {\em psudo-}vers…
Tridiagonality, supersymmetry and non self-adjoint Hamiltonians
F. Bagarello, F. Gargano, F. Roccati
In this paper we consider some aspects of tridiagonal, non self-adjoint, Hamiltonians and of their supersymmetric counterparts. In particular, the problem of factorization is discu…
Quantum mechanical settings inspired by RLC circuits
G. Alicata, F. Bagarello, F. Gargano +1
In some recent papers several authors used electronic circuits to construct loss and gain systems. This is particularly interesting in the context of PT-quantum mechanics, where th…
Pseudo-Bosons from Landau Levels
Fabio Bagarello
We construct examples of pseudo-bosons in two dimensions arising from the Hamiltonian for the Landau levels. We also prove a no-go result showing that non-linear combinations of bo…
