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 …

Quantum reservoir computing in atomic lattices

G Llodrà, P Mujal, R Zambrini, GL Giorgi - arxiv preprint arxiv:2411.13401, 2024 - arxiv.org
Quantum reservoir computing (QRC) exploits the dynamical properties of quantum systems
to perform machine learning tasks. We demonstrate that optimal performance in QRC can be …

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 …

Meson-polariton and string dynamics via cavity coupling in Rydberg atom array

Z Bacciconi, HB Xavier, M Marinelli, DS Bhakuni… - arxiv preprint arxiv …, 2025 - arxiv.org
We investigate the real time meson and string dynamics of one dimensional Rydberg atom
arrays in presence of a collective cavity mode. We derive an effective description in terms of …
