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…
Random-matrix models of monitored quantum circuits
Vir B. Bulchandani, S. L. Sondhi, J. T. Chalker
We study the competition between Haar-random unitary dynamics and measurements for unstructured systems of qubits. For projective measurements, we derive various properties of the…
Local resonances and parametric level dynamics in the many-body localised phase
S. J. Garratt, Sthitadhi Roy, J. T. Chalker
By varying the disorder realisation in the many-body localised (MBL) phase, we investigate the influence of resonances on spectral properties. The standard theory of the MBL phase…
Spectral Lyapunov exponents in chaotic and localized many-body quantum systems
Amos Chan, Andrea De Luca, J. T. Chalker
We consider the spectral statistics of the Floquet operator for disordered, periodically driven spin chains in their quantum chaotic and many-body localized phases (MBL). The spect…
