Quantum Enhancement of Thermalization
Yulong Qiao, Frank GroÃmann, Peter Schlagheck +1
Equilibrium properties of many-body systems with a large number of degrees of freedom are generally expected to be described by statistical mechanics. Such expectations are closely…

Prethermalization in Fermi-Pasta-Ulam-Tsingou chains
Gabriel M. Lando, Sergej Flach
The observation of the Fermi-Pasta-Ulam-Tsingou (FPUT) paradox, namely the lack of equipartition in the evolution of a normal mode in a nonlinear chain on unexpectedly long times,…

Observation of prethermalization in weakly nonintegrable unitary maps
Xiaodong Zhang, Gabriel M. Lando, Barbara Dietz +1
We investigate prethermalization by studying the statistical properties of the time-dependent largest Lyapunov exponent for unitary-circuit maps upon approaching integrabil…
