N Defenu, A Lerose, S Pappalardi - Physics Reports, 2024 - Elsevier
Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

Lindblad master equations for quantum systems coupled to dissipative bosonic modes

SB Jäger, T Schmit, G Morigi, MJ Holland… - Physical Review Letters, 2022 - APS
We present a general approach to derive Lindblad master equations for a subsystem whose
dynamics is coupled to dissipative bosonic modes. The derivation relies on a Schrieffer …

Mesoscopic coherence in light scattering from cold, optically dense and disordered atomic systems

DV Kupriyanov, IM Sokolov, MD Havey - Physics Reports, 2017 - Elsevier
Coherent effects manifested in light scattering from cold, optically dense and disordered
atomic systems are reviewed from a primarily theoretical point of view. Development of the …

Ensemble inequivalence in long-range quantum systems

N Defenu, D Mukamel, S Ruffo - Physical Review Letters, 2024 - APS
Ensemble inequivalence, ie, the possibility of observing different thermodynamic properties
depending on the statistical ensemble which describes the system, is one of the hallmarks of …

Metastability and discrete spectrum of long-range systems

N Defenu - Proceedings of the National Academy of Sciences, 2021 - pnas.org
Long-lived quasi-stationary states (QSSs) are a signature characteristic of long-range
interacting systems both in the classical and in the quantum realms. Often, they emerge after …

Signatures of prethermalization in a quenched cavity-mediated long-range interacting Fermi gas

Z Wu, J Fan, X Zhang, J Qi, H Wu - Physical Review Letters, 2023 - APS
The coupling of ultracold quantum gases to an optical cavity provides an ideal system for
studying the novel long-range interacting nonequilibrium dynamics. Here we report an …

Validity of mean-field theory in a dissipative critical system: Liouvillian gap, -symmetric antigap, and permutational symmetry in the model

D Huybrechts, F Minganti, F Nori, M Wouters… - Physical Review B, 2020 - APS
We study the all-to-all connected XYZ (anisotropic-Heisenberg) spin model with local and
collective dissipations, comparing the results of mean-field (MF) theory with the solution of …

-Band Induced Self-Organization and Dynamics with Repulsively Driven Ultracold Atoms in an Optical Cavity

P Zupancic, D Dreon, X Li, A Baumgärtner, A Morales… - Physical review …, 2019 - APS
We investigate a Bose-Einstein condensate strongly coupled to an optical cavity via a
repulsive optical lattice. We detect a stable self-ordered phase in this regime, and show that …

The world of long-range interactions: A bird's eye view

S Gupta, S Ruffo - International Journal of Modern Physics A, 2017 - World Scientific
In recent years, studies of long-range interacting (LRI) systems have taken center stage in
the arena of statistical mechanics and dynamical system studies, due to new theoretical …

Relaxation dynamics in a Hubbard dimer coupled to fermionic baths: Phenomenological description and its microscopic foundation

E Kleinherbers, N Szpak, J König, R Schützhold - Physical Review B, 2020 - APS
We study relaxation dynamics in a strongly interacting two-site Fermi-Hubbard model that is
induced by coupling each site to a local fermionic bath. To derive the proper form of the …
