A semi-classical versus quantum description of the ground state of three-level atoms interacting with a one-mode electromagnetic field
S. Cordero, O. Castaños, R. López-Peña +1
We consider three-level atoms (or systems) interacting with a one-mode electromagnetic field in the dipolar and rotating wave approximations. The order of the quantum phase t…
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…
