Quantum Phase Diagrams of Matter-Field Hamiltonians II: Wigner Function Analysis
Ramón López-Peña, Sergio Cordero, Eduardo Nahmad-Achar +1
Non-classical states are of practical interest in quantum computing and quantum metrology. These states can be detected through their Wigner function negativity in some regions. In…

Quantum Phase Diagrams of Matter-Field Hamiltonians I: Fidelity, Bures Distance, and Entanglement
Sergio Cordero, Eduardo Nahmad-Achar, Ramón López-Peña +1
A general procedure is established to calculate the quantum phase diagrams for finite matter-field Hamiltonian models. The minimum energy surface associated to the different symmet…
