Confined and deconfined chaos in classical spin systems
Hyeongjin Kim, Robin Schäfer, David M. Long +2
Weakly perturbed integrable many-body systems are typically chaotic, and thermal at late times. However, there are distinct relationships between the timescales for thermalization…

Probing Hilbert space fragmentation using controlled dephasing
Dominik Vuina, Robin Schäfer, David M. Long +1
Dynamical constraints in many-body quantum systems can lead to Hilbert space fragmentation, wherein the system's evolution is restricted to small subspaces of Hilbert space called…

Predicting Dynamics from Flows of the Eigenstate Thermalization Hypothesis
Dominik Hahn, David M. Long, Marin Bukov +1
Analytical treatments of far-from-equilibrium quantum dynamics are few, even in well-thermalizing systems. The celebrated eigenstate thermalization hypothesis (ETH) provides a post…
