Non-standard quantum algebras and finite dimensional -symmetric systems
Ángel Ballesteros, Romina Ramírez, Marta Reboiro
In this work, -symmetric Hamiltonians defined on quantum algebras are presented. We study the spectrum of a family of non-Hermitian Hamiltonians wr…

Psedo-hermitian Hamiltonians at finite temperature
Romina Ramírez, Marta Reboiro
The Double Green Function Formalism has been extensively used in dealing with the thermodynamics of quantum systems which evolved in time under the action of a given self-adjoint H…

About radial Toeplitz operators on Segal-Bargmann and spaces
Romina A. Ramírez, Gerardo L. Rossini, Marcela Sanmartino
We discuss Toeplitz operators on the Segal-Bargmann space as functional realizations of anti-Wick operators on the Fock space. In the special case of radial symbols we exploit the…
