Quantum multifractality as a probe of phase space in the Dicke model

MA Bastarrachea-Magnani, D Villaseñor… - Physical Review E, 2024 - APS
We study the multifractal behavior of coherent states projected in the energy eigenbasis of
the spin-boson Dicke Hamiltonian, a paradigmatic model describing the collective …

Integrability, multifractality, and two-photon dynamics in disordered Tavis-Cummings models

A Wierzchucka, F Piazza, PW Claeys - Physical Review A, 2024 - APS
The Tavis-Cummings model is a paradigmatic central-mode model in which a set of two-
level quantum emitters (spins) are coupled to a collective cavity mode. Here we study the …
