Lyapunov spectrum scaling transition for quasiperiodic nonlinear unitaries
Xiaodong Zhang, Barbara Dietz, Sergej Flach
The paper investigates how the Lyapunov spectrum of weakly nonlinear unitary maps changes with the localization length in quasiperiodic potentials, revealing a delayed scaling tran…

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…
