[HTML][HTML] Out-of-equilibrium dynamics of quantum many-body systems with long-range interactions

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 …

Floquet prethermal order by disorder

HK **, J Knolle - Physical Review Research, 2024 - APS
Frustrated magnets can have accidental ground state degeneracies which may be lifted by
various forms of disorder, for example in the form of thermal or quantum fluctuations. This …

Prethermal time-crystalline spin ice and monopole confinement in a driven magnet

M Yue, Z Cai - Physical Review Letters, 2023 - APS
Studies of systems far from equilibrium open up new avenues for investigating exotic phases
of matter. A driven-dissipative frustrated spin system is examined in this study, and we …

Prethermalization in periodically driven nonreciprocal many-body spin systems

AJ McRoberts, H Zhao, R Moessner, M Bukov - Physical Review Research, 2023 - APS
We analyze a new class of time-periodic nonreciprocal dynamics in interacting chaotic
classical spin systems, whose equations of motion are conservative (phase-space-volume …

Space-time symmetry breaking in nonequilibrium frustrated magnetism

M Yue, Z Cai - Physical Review B, 2023 - APS
Spontaneous symmetry breaking is responsible for rich phenomena in equilibrium physics.
Driving a system out-of-equilibrium can significantly enrich the possibility of spontaneous …

Floquet-engineered emergent massive Nambu-Goldstone modes

Y Hou, Z Fu, R Moessner, M Bukov, H Zhao - arxiv preprint arxiv …, 2024 - arxiv.org
We present a general framework to implement massive Nambu-Goldstone quasi-particles in
driven many-body systems. The underlying mechanism leverages an explicit Lie group …

Residual entropy and magnetocaloric effect in a diluted sawtooth spin model of hole-doped CuO chains

MJ Cirino, O Rojas, SM de Souza, J Torrico, ML Lyra… - Physical Review E, 2023 - APS
Ground-state and magnetocaloric properties of a site-diluted sawtooth magnetic chain in the
presence of an external magnetic field are exactly investigated by using the transfer-matrix …

Characteristics of an Ising-like Model with Ferromagnetic and Antiferromagnetic Interactions

B Kryzhanovsky, V Egorov, L Litinskii - Entropy, 2023 - mdpi.com
In the framework of mean field approximation, we consider a spin system consisting of two
interacting sub-ensembles. The intra-ensemble interactions are ferromagnetic, while the …

Ferromagnetic ordering in mazelike stripe liquid of a dipolar six-state clock model

Q Simmons, SZ Lin, GW Chern - arxiv preprint arxiv:2412.09550, 2024 - arxiv.org
We present a comprehensive numerical study of a six-state clock model with a long-range
dipolar type interaction. This model is motivated by the ferroelectric orders in the multiferroic …

Nonreciprocal frustration: Time crystalline order-by-disorder phenomenon and a spin-glass-like state

R Hanai - Physical Review X, 2024 - APS
Active systems are composed of constituents with interactions that are generically
nonreciprocal in nature. Such nonreciprocity often gives rise to situations where conflicting …
