Quantum phase transition in the Dicke model with critical and non-critical entanglement
L. Bakemeier, A. Alvermann, H. Fehske
We study the quantum phase transition of the Dicke model in the classical oscillator limit, where it occurs already for finite spin length. In contrast to the classical spin limit,…

Collapse-revival dynamics and atom-field entanglement in the non-resonant Dicke model
A. Alvermann, L. Bakemeier, H. Fehske
We consider the dynamics of atomic and field coherent states in the non-resonant Dicke model. At weak coupling an initial product state evolves into a superposition of multiple fie…
