Quantum phase transitions of three-level atoms interacting with a one-mode electromagnetic field
Sergio Cordero, Ramón López-Peña, Octavio Castaños +1
We apply the energy surface method to study a system of Na three-level atoms interacting with a one-mode radiation field in the Ξ, Λand V configurations. We obtain an estimation of…

Analytical study of quadratic and non-quadratic short-time behavior of quantum decay
Sergio Cordero, Gastón García-Calderón
The short-time behavior of quantum decay of an unstable state initially located within an interaction region of finite range is investigated using a resonant expansion of the survi…
