Effects of quenching protocols based on parametric oscillators
Mariagiovanna Gianfreda, Giulio Landolfi
We consider the problem of understanding the basic features displayed by quantum systems described by parametric oscillators whose time-dependent frequency parameter varies…
Scattering off PT-symmetric upside-down potentials
Carl M. Bender, Mariagiovanna Gianfreda
The upside-down , , and potentials with appropriate PT-symmetric boundary conditions have real, positive, and discrete quantum-mechanical spectra. This paper pro…
Non-autonomous Hamiltonian quantum systems, operator equations and representations of Bender-Dunne Weyl ordered basis under time-dependent canonical transformations
Mariagiovanna Gianfreda, Giulio Landolfi
We address the problem of integrating operator equations concomitant with the dynamics of non autonomous quantum systems by taking advantage of the use of time-dependent canonical…
Bound states, scattering states and resonant states in PT-symmetric open quantum systems
Savannah Garmon, Mariagiovanna Gianfreda, Naomichi Hatano
We study a simple open quantum system with a PT-symmetric defect potential as a prototype to illustrate general features of PT-symmetric open quantum systems; however, the potentia…
