Avalanches and many-body resonances in many-body localized systems

A Morningstar, L Colmenarez, V Khemani, DJ Luitz… - Physical Review B, 2022 - APS
We numerically study both the avalanche instability and many-body resonances in strongly

Dynamical purification and the emergence of quantum state designs from the projected ensemble

M Ippoliti, WW Ho - PRX Quantum, 2023 - APS
Quantum thermalization in a many-body system is defined by the approach of local
subsystems toward a universal form, describable as an ensemble of quantum states wherein …

Temporal entanglement in chaotic quantum circuits

A Foligno, T Zhou, B Bertini - Physical Review X, 2023 - APS
The concept of space evolution (or space-time duality) has emerged as a promising
approach for studying quantum dynamics. The basic idea involves exchanging the roles of …

Many-body quantum chaos and emergence of Ginibre ensemble

S Shivam, A De Luca, DA Huse, A Chan - Physical review letters, 2023 - APS
We show that non-Hermitian Ginibre random matrix behaviors emerge in spatially extended
many-body quantum chaotic systems in the space direction, just as Hermitian random matrix …

Exact quench dynamics of the Floquet quantum East model at the deterministic point

B Bertini, C De Fazio, JP Garrahan, K Klobas - Physical Review Letters, 2024 - APS
We study the nonequilibrium dynamics of the Floquet quantum East model (a Trotterized
version of the kinetically constrained quantum East spin chain) at its “deterministic point,” …

Growth of Rényi entropies in interacting integrable models and the breakdown of the quasiparticle picture

B Bertini, K Klobas, V Alba, G Lagnese, P Calabrese - Physical Review X, 2022 - APS

Quantum Information Spreading in Generalized Dual-Unitary Circuits

A Foligno, P Kos, B Bertini - Physical Review Letters, 2024 - APS
We study the spreading of quantum information in a recently introduced family of brickwork
quantum circuits that generalizes the dual-unitary class. These circuits are unitary in time …
