Symmetry Adapted Coherent States for Three-Level Atoms Interacting with One-Mode Radiation
R. López-Peña, S. Cordero, E. Nahmad-Achar +1
We introduce a combination of coherent states as variational test functions for the atomic and radiation sectors to describe a system of Na three- level atoms interacting with a on…
Polychromatic phase diagram for -level atoms interacting with modes of electromagnetic field
Sergio Cordero, Eduardo Nahmad-Achar, Ramón López-Peña +1
A system of atoms of -levels interacting dipolarly with modes of electromagnetic field is considered. The energy surface of the system is constructed from the direc…
Lorentz transformations for massive two-particle systems: entanglement change and invariant subspaces
Esteban Castro-Ruiz, Eduardo Nahmad-Achar
Lorentz boosts on particles with spin and momentum degrees of freedom induce momentum-dependent rotations. Since, in general, different particles have different momenta, the transf…
Phase Diagrams of Systems of 2 and 3 levels in the presence of a Radiation Field
Eduardo Nahmad-Achar, Sergio Cordero, Octavio Castaños +1
We study the structure of the phase diagram for systems consisting of 2- and 3- level particles dipolarly interacting with a 1-mode electromagnetic field, inside a cavity, paying p…
