Dynamics of a harmonic oscillator coupled with a Glauber amplifier
R. Grimaudo, V. I. Man'ko, M. A. Man'ko +1
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system…
Proposal of a computational approach for simulating thermal bosonic fields in phase space
Alessandro Sergi, Roberto Grimaudo, Gabriel Hanna +1
When a quantum field is in contact with a thermal bath, the vacuum state of the field may be generalized to a thermal vacuum state, which takes into account the thermal noise. In t…
Analytically solvable -symmetry dynamics from su(1,1)-symmetry problems
R. Grimaudo, A. S. M. de Castro, H. Nakazato +1
A protocol for explicitly constructing the exact time-evolution operators generated by time-dependent -symmetry Hamiltonians is reported. Its mathematical applicab…
Landau-Majorana-Stuckelberg-Zener dynamics driven by coupling for two interacting qutrit systems
R. Grimaudo, N. V. Vitanov, A. Messina
A time-dependent two interacting spin-qutrit model is analysed and solved. The two interacting qutrits are subjected to a longitudinal field linearly varying over time as in the La…
