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…
Symmetry re-breaking in an effective theory of quantum coarsening
Federico Balducci, Anushya Chandran, Roderich Moessner
We present a simple theory accounting for two central observations in a recent experiment on quantum coarsening and collective dynamics on a programmable quantum simulator [T. Mano…
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…
The Moving Born-Oppenheimer Approximation
Bernardo Barrera, Daniel P. Arovas, Anushya Chandran +1
We develop a mixed quantum-classical framework, dubbed the Moving Born-Oppenheimer Approximation (MBOA), to describe the dynamics of slow degrees of freedom (DOFs) coupled to fast…
A strong-driving toolkit for topological Floquet energy pumps with superconducting circuits
Martin Ritter, David M. Long, Qianao Yue +3
Topological Floquet energy pumps -- which use periodic driving to create a topologically protected quantized energy current -- have been proposed and studied theoretically, but hav…
