Random quantum circuits, chaos and quantum thermalization
J. T. Chalker
These notes accompany lectures given in June 2025 at the summer school \emph{Fundamental Problems in Statistical Physics XVI}. They offer a short introduction to random quantum cir…

Chaotic many-body quantum dynamics, spectral correlations, and energy diffusion
J. T. Chalker, Dominik Hahn
We study chaotic many-body quantum dynamics in a minimal model with spatial structure and local interactions. It has a time-independent Hamiltonian, in contrast to quantum circuits…

Operator dynamics in Floquet many-body systems
Takato Yoshimura, Samuel J. Garratt, J. T. Chalker
We study operator dynamics in many-body quantum systems, focusing on generic features of systems that are ergodic, spatially extended, and lack conserved densities. Quantum circuit…
