Compelling Bounds on Equilibration Times -- the Issue with Fermi's Golden Rule
Robin Heveling, Lars Knipschild, Jochen Gemmer
Putting a general, physically relevant upper bound on equilibration times in closed quantum systems is a recently much pursued endeavor. In PRX, 7, 031027 (2017) Garc\'ıa-Pintos et…
Exponential damping induced by random and realistic perturbations
Jonas Richter, Fengping Jin, Lars Knipschild +4
Given a quantum many-body system and the expectation-value dynamics of some operator, we study how this reference dynamics is altered due to a perturbation of the system's Hamilton…
Decoherence Entails Exponential Forgetting in Systems Complying with the Eigenstate Thermalization Hypothesis
Lars Knipschild, Jochen Gemmer
According to the eigenstate thermalization ansatz, matrices representing generic few body observables take on a specific form when displayed in the eigenbasis of a chaotic Hamilton…
