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…
Semiclassical bifurcations and topological phase transitions in a one-dimensional lattice of coupled Lipkin-Meshkov-Glick models
A. V. Sorokin, M. Aparicio Alcalde, V. M. Bastidas +3
In this work we study a one-dimensional lattice of Lipkin-Meshkov-Glick models with alternating couplings between nearest-neighbors sites, which resembles the Su-Schrieffer-Heeger…
Single-Bubble Sonoluminescence as Dicke Superradiance at Finite Temperature
M. Aparicio Alcalde, Hernando Quevedo, Nami Fux Svaiter
Sonoluminescence is a process in which a strong sound field is used to produce light in liquids. We explain sonoluminescence as a phase transition from ordinary fluorescence to a s…
Thermal phase transitions for Dicke-type models in the ultra-strong coupling limit
M. Aparicio Alcalde, M. Bucher, C. Emary +1
We consider the Dicke model in the ultra-strong coupling limit to investigate thermal phase transitions and their precursors at finite particle numbers for bosonic and fermioni…
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…
