Lévy Sachdev-Ye-Kitaev Model
Budhaditya Bhattacharjee, William E. Salazar, Dario Rosa +1
We explore the spectral properties of the -fermion Sachdev-Ye-Kitaev model with interaction sourced from a Lévy Stable (fat-tailed) distribution. Lévy random matrices are know…

From Dyson Models to Many-Body Quantum Chaos
Alexei Andreanov, Matteo Carrega, Jeff Murugan +3
A deep understanding of the mechanisms underlying many-body quantum chaos is one of the big challenges in contemporary theoretical physics. We tackle this problem in the context of…

Thermalization slowing down of weakly nonintegrable quantum spin dynamics
Budhaditya Bhattacharjee, Alexei Andreanov, Sergej Flach
We study thermalization slowing down of a quantum many-body spin system upon approach to two distinct integrability limits. Motivated by previous studies of classical systems, we i…
