Berry phase of the Tavis-Cummings model with three modes of oscillation
E. Choreño, D. Ojeda-Guillén, R. Valencia +1
In this paper we develop a general method to obtain the Berry phase of time-dependent Hamiltonians with a linear structure given in terms of the and groups. This…
algebraic approach of the most general Hamiltonian of a two-level system in two-dimensional geometry
E. Choreño, D. Ojeda-Guillén
In this paper we introduce the bosonic generators of the algebra and study some of their properties, based on the and group theory. With the developed t…
Exact Solution of the Relativistic Dunkl Oscillator in Dimensions
R. D. Mota, D. Ojeda-Guillén, M. Salazar-Ramírez +1
In this paper we study the -dimensional Dirac-Dunkl oscillator coupled to an external magnetic field. Our Hamiltonian is obtained from the standard Dirac oscillator coupled…
Algebraic approach and coherent states for a relativistic quantum particle in cosmic string spacetime
M. Salazar-Ramírez, D. Ojeda-Guillén, R. D. Mota
We study a relativistic quantum particle in cosmic string spacetime in the presence of a uniform magnetic field and a Coulomb-type scalar potential. It is shown that the radial par…
