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…
Exact dynamics and qubit inversion of non-Hermitian driven two-level systems
Ivan A. Bocanegra-Garay, Luis M. Nieto
The supersymmetric structure of a generalized non-Hermitian driven two-level system is demonstrated. A unitary rotation turns the Hamiltonian into a more convenient form. After dec…
Low-Energy DNA Bubble Dynamics via the Quantum Coulomb Potential
Juan D. GarcÃa-Muñoz, A. Contreras-Astorga, L. M. Nieto
We developed a low-energy model that can be used at any time to describe the dynamics of DNA bubbles at temperatures below the melting point. The Schrödinger equation associated w…
Parity-deformed , and Algebras: a Basis for Quantum Optics and Quantum Communications Applications
W. S. Chung, H. Hassanabadi, L. M. Nieto +1
Having in mind the significance of parity (reflection) in various areas of physics, the single-mode and two-mode Wigner algebras are considered adding to them a reflection operator…
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…
