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 integrabili…
Thermalization Universality-Class Transition Induced by Anderson Localization
Weihua Zhang, Gabriel M. Lando, Barbara Dietz +1
We study the disorder-induced crossover between the two recently discovered thermalization slowing-down universality classes -- characterized by long- and short-range coupling -- i…
Quantum-Chaotic Evolution Reproduced from Effective Integrable Trajectories
Gabriel M. Lando, Alfredo M. Ozorio de Almeida
Classically integrable approximants are here constructed for a family of predominantly chaotic periodic systems by means of the Baker-Hausdorff-Campbell formula. We compare the evo…
Semiclassical evolution in phase space for a softly chaotic system
Gabriel M. Lando, Alfredo M. Ozorio de Almeida
An initial coherent state is propagated exactly by a kicked quantum Hamiltonian and its associated classical stroboscopic map. The classical trajectories within the initial state a…
