Hidden Symmetry of the Generalized Landau-Zener Vibronic Model
L. M. Nieto, S. Zarrinkamar
The one-dimensional harmonic vibronic model, which is a generalization of the so-called linear Landau-Zener model and appears in the form of coupled Schrödinger equations, is revis…

Exact Floquet solutions in a Parity-Time-Symmetric Rabi Model
M. Baradaran, D. Braak, L. M. Nieto +1
It is shown that a semiclassical Rabi model with parity-time (PT) symmetry has a hidden symmetry and hence possesses quasi-exact solutions. These are located precisely at t…

Generalized Coulomb-type interaction embedded in a non-inertial cosmic string spacetime in a slow-rotation limit
M. Baradaran, L. M. Nieto, S. Zarrinkamar
Motivated by the great interest in studying quantum and gravitational phenomena in a unified way, scalar bosons are considered in a cosmic string spacetime and in a non-inertial fr…
