Universal Dynamical Response to Slow Driving in Chaotic Systems
Nachiket Karve, Nathan Rose, David Campbell +1
We propose a unified perspective on classical and quantum chaos based on the stability of a system's stationary states under slow driving. We probe this sensitivity via the system'…
Sensitivity to perturbations in the three-dimensional Anderson model
Piotr Tokarczyk, Lev Vidmar, Anatoli Polkovnikov +1
We investigate the fidelity susceptibility, which quantifies the sensitivity of single-particle eigenstates to perturbations, in the three-dimensional Anderson model. As a function…
Temperature and integrability-breaking correspondence via adiabatic transformations
Hyeongjin Kim, Souvik Bandyopadhyay, Anatoli Polkovnikov
We reveal a correspondence between temperature and integrability-breaking in classical and quantum many-body systems through the lens of geometry and adiabatic transformations. Dec…
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…
Universal Counterdiabatic Driving
Stewart Morawetz, Anatoli Polkovnikov
Local counterdiabatic (CD) driving provides a systematic way of constructing a control protocol to approximately suppress the excitations resulting from changing some parameter(s)…
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…
