Thermalization of Weakly Nonintegrable FPUT and Toda Dynamics: A Lyapunov Spectrum Perspective

Aniket Patra, Sergej Flach

We study the thermalization slowing down of Fermi-Past-Ulam-Tsingou (FPUT) chains and of Toda chains with nonintegrable boundaries. We focus on the transition from FPUT to harmonic…

Measuring FPUT thermalization with Toda integrals

Helen Christodoulidi, Sergej Flach

We assess the ergodic properties of the Fermi-Pasta-Ulam-Tsingou-I^± model for generic initial conditions using a Toda integral. It serves as an adiabatic invariant for the system…

Trotter transition in BCS pairing dynamics

Aniket Patra, Emil A. Yuzbashyan, Boris L. Altshuler +1

We study universal aspects of thermalization induced by Trotterization, a procedure routinely used in gate-based quantum computation. We use the reduced-BCS model -- quantum integr…
