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…

Matrix diagonalization and exact solution of the k-photon Jaynes-Cummings model
E. Choreño, D. Ojeda-Guillén, V. D. Granados
We study and exactly solve the two-photon and k-photon Jaynes-Cummings models by using a novelty algebraic method. This algebraic method is based on the Pauli matrices realization…
