Classical route to ergodicity and scarring in collective quantum systems

S Sinha, S Ray, S Sinha - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
Ergodicity, a fundamental concept in statistical mechanics, is not yet a fully understood
phenomena for closed quantum systems, particularly its connection with the underlying …

Hilbert space fragmentation in a long-range system

G Francica, L Dell'Anna - Physical Review B, 2023 - APS
We study the role of the interaction range on the Hilbert-space fragmentation and many-
body scar states considering a spin-1/2 many-body Hamiltonian describing a generalized …

Quantum many-body scar models in one-dimensional spin chains

Prethermalization in the PXP model under continuous quasiperiodic driving

P Dutta, S Choudhury, V Shukla - Physical Review B, 2025 - APS
Motivated by recent experiments realizing long-lived nonequilibrium states in aperiodically
driven quantum many-body systems, we investigate the dynamics of a quasiperiodically …

Quantum many-body scars in spin-1 Kitaev chain with uniaxial single-ion anisotropy

WY Zhang, YN Wang, D Liu, J Ren, J Li, N Wu… - Physical Review B, 2023 - APS
To establish a solid-state-based framework for the coexistence of quantum many-body scars
and quantum criticality, we investigate the spin-1 Kitaev chain with uniaxial single-ion …
