Analytic Approximation of the Tavis-Cummings Ground State via Projected States
Octavio Castanos, Eduardo Nahmad-Achar, Ramon Lopez-Pena +1
We show that an excellent approximation to the exact quantum solution of the ground state of the Tavis-Cummings model is obtained by means of a semi-classical projected state. This…

Coherent State Description of the Ground State in the Tavis-Cummings Model and its Quantum Phase Transitions
Octavio Castanos, Ramon Lopez-Pena, Eduardo Nahmad-Achar +3
Quantum phase transitions and observables of interest of the ground state in the Tavis-Cummings model are analyzed, for any number of atoms, by using a tensorial product of coheren…
