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…
Time-evolution of quantum systems via a complex nonlinear Riccati equation. I. Conservative systems with time-independent Hamiltonian
Hans Cruz, Dieter Schuch, Octavio Castaños +1
The sensitivity of the evolution of quantum uncertainties to the choice of the initial conditions is shown via a complex nonlinear Riccati equation leading to a reformulation of qu…
New supersymmetry-generated complex potentials with real spectra
Oscar Rosas-Ortiz, Octavio Castanos, Dieter Schuch
A new form to construct complex superpotentials that produce real energy spectra in supersymmetric quantum mechanics is presented. This is based on the relation between the nonline…
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…
