Enhancement of efficiency in the Dicke model quantum heat engine
M. Aparicio Alcalde, E. Arias, N. F. Svaiter
We analyze a quantum heat engine described by the full Dicke model. The system exhibit quantum phase transitions under certain conditions. We consider the system performing a Stirl…
Path integral approach to the full Dicke model with dipole-dipole interaction
M. Aparicio Alcalde, J. Stephany, N. F. Svaiter
We consider the full Dicke spin-boson model composed by a single bosonic mode and an ensemble of identical two-level atoms with different couplings for the resonant and anti-re…
Path integral approach to the full Dicke model
M. Aparicio Alcalde, B. M. Pimentel
The full Dicke model describes a system of identical two level-atoms coupled to a single-mode quantized bosonic field. The model considers rotating and counter-rotating couplin…
Entangled States and Super-radiant Phase Transition
M. Aparicio Alcalde, A. H. Cardenas, N. F. Svaiter +1
The Dicke spin-boson model is composed by a single bosonic mode and an ensemble of identical two-level atoms. Assuming thermal equilibrium with a reservoir at temperature $β^{-…
Virtual Processes and Superradiance in Spin-Boson Models
M. Aparicio Alcalde, R. Kullock, N. F. Svaiter
We consider spin-boson models composed by a single bosonic mode and an ensemble of identical two-level atoms. The situation where the coupling between the bosonic mode and the…
Functional Methods in the Generalized Dicke Model
M. Aparicio Alcade, A. L. L. de Lemos, N. F. Svaiter
The Dicke model describes an ensemble of N identical two-level atoms (qubits) coupled to a single mode of a bosonic field. The fermion Dicke model should be obtained by changing th…
