Analytical Solutions to Asymmetric Two-Photon Rabi Model
M. Baradaran, L. M. Nieto, S. Zarrinkamar
Within the Segal-Bargmann representation, a generalized Rabi model is considered that includes both two-photon and asymmetric terms. It is shown that, through a suitable transforma…
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…
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 revi…
Dirac Equation with Space Contributions Embedded in a Quantum-Corrected Gravitational Field
M. Baradaran, L. M. Nieto, S. Zarrinkamar
The Dirac equation is considered with the recently proposed generalized gravitational interaction (Kepler or Coulomb), which includes post-Newtonian (relativistic) and quantum corr…
The spin-one Duffin-Kemmer-Petiau equation revisited: analytical study of its structure and a careful choice of interaction
M. Baradaran, L. M. Nieto, L. P. de Oliveira +1
The Duffin-Kemmer-Petiau equation is investigated for spin one bosons with the so-called natural (normal) and unnatural (abnormal) parity states for non-minimal vector interactions…
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…
