Critical phenomena in an extended Dicke model
J. P. J. Rodriguez, S. A. Chilingaryan, B. M. Rodríguez-Lara
Spectral characterization is a fundamental step in the development of useful quantum technology platforms. Here, we study an ensemble of interacting qubits coupled to a single quan…
Exceptional solutions in two-mode quantum Rabi models
S. A. Chilingaryan, B. M. Rodríguez-Lara
We study two models describing the interaction of a two-level system with two quantum field modes. The first one is equivalent to a dissipative two-state system with just two boson…
Searching for structure beyond parity in the two-qubit Dicke model
B. M. Rodríguez-Lara, S. A. Chilingaryan, H. M. Moya-Cessa
We try to classify the spectrum of the two-qubit Dicke model by calculating two quantum information measures of its eigenstates: the Wooters concurrence and the mutual quantum info…
The quantum Rabi model for two qubits
S. A. Chilingaryan, B. M. Rodríguez-Lara
We study the two-qubit Rabi model in the most general case where the qubits are different from each other. The spectrum of the system in the ultrastrong-coupling regime is shown to…
Ground state in the finite Dicke model for interacting qubits
R. A. Robles Robles, S. A. Chilingaryan, B. M. Rodríguez-Lara +1
We study the ground state of a finite size ensemble of interacting qubits driven by a quantum field. We find a maximally entangled W-state in the ensemble part of the system for a…
