Coherent and semiclassical states of a free particle
V. G. Bagrov, D. M. Gitman, A. S. Pereira
Coherent states (CS) were first introduced and studied in detail for bound motion and discrete-spectrum systems like harmonic oscillators and similar systems with a quadratic Hamil…
Coherent states of systems with quadratic Hamiltonians
V. G. Bagrov, D. M. Gitman, A. S. Pereira
Different families of generalized CS for one-dimensional systems with general time dependent quadratic Hamiltonian are constructed. In principle, all known CS of systems with quadr…
Aspects of Two-Level Systems under External Time Dependent Fields
V. G. Bagrov, J. C. A. Barata, D. M. Gitman +1
The dynamics of two-level systems in time-dependent backgrounds is under consideration. We present some new exact solutions in special backgrounds decaying in time. On the other ha…
