Bi-coherent states as generalized eigenstates of the position and the momentum operators
Fabio Bagarello, Francesco Gargano
In this paper we show that the position and the derivative operators, and , can be treated as ladder operators connecting the various vectors of two biorthonormal…
Modeling epidemics through ladder operators
F. Bagarello, F. Gargano, F. Roccati
We propose a simple model of spreading of some infection in an originally healthy population which is different from other models existing in the literature. In particular, we use…
Eigenvalues of non-hermitian matrices: a dynamical and an iterative approach. Application to a truncated Swanson model
Fabio Bagarello, Francesco Gargano
We propose two different strategies to find eigenvalues and eigenvectors of a given, not necessarily Hermitian, matrix . Our methods apply also to the case of complex eigenvalue…
Reply to Comment on "A no-go result for the quantum damped harmonic oscillator"
F. Bagarello, F. Gargano, F. Roccati
In a recent paper, \cite{deguchi}, Deguchi and Fujiwara claim that our results in \cite{BGR} are wrong, and compute what they claim is the square integrable vacuum of their annihil…
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…
A no-go result for the quantum damped harmonic oscillator
Fabio Bagarello, Francesco Gargano, Federico Roccati
In this letter we show that it is not possible to set up a canonical quantization for the damped harmonic oscillator using the Bateman lagrangian. In particular, we prove that no s…
