N Defenu, A Lerose, S Pappalardi - Physics Reports, 2024 - Elsevier
Experimental progress in atomic, molecular, and optical platforms in the last decade has
stimulated strong and broad interest in the quantum coherent dynamics of many long-range …

Nonlinear sigma models for monitored dynamics of free fermions

M Fava, L Piroli, T Swann, D Bernard, A Nahum - Physical Review X, 2023 - APS
We derive field theory descriptions for measurement-induced phase transitions in free
fermion systems. We focus on a multiflavor Majorana chain, undergoing Hamiltonian …

Measurement-induced phase transition in the monitored Sachdev-Ye-Kitaev model

SK Jian, C Liu, X Chen, B Swingle, P Zhang - Physical review letters, 2021 - APS
We construct Brownian Sachdev-Ye-Kitaev (SYK) chains subjected to continuous monitoring
and explore possible entanglement phase transitions therein. We analytically derive the …

Scrambling dynamics and out-of-time-ordered correlators in quantum many-body systems

S Xu, B Swingle - PRX quantum, 2024 - APS
This tutorial article introduces the physics of quantum information scrambling in quantum
many-body systems. The goals are to understand how to precisely quantify the spreading of …

Scrambling is necessary but not sufficient for chaos

N Dowling, P Kos, K Modi - Physical Review Letters, 2023 - APS
We show that out-of-time-order correlators (OTOCs) constitute a probe for local-operator
entanglement (LOE). There is strong evidence that a volumetric growth of LOE is a faithful …

Quantum entanglement in the Sachdev—Ye—Kitaev model and its generalizations

P Zhang - Frontiers of Physics, 2022 - Springer
Entanglement is one of the most important concepts in quantum physics. We review recent
progress in understanding the quantum entanglement in many-body systems using large-N …

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 …

Designs via free probability

M Fava, J Kurchan, S Pappalardi - Physical Review X, 2025 - APS
Unitary designs have become a vital tool for investigating pseudorandomness, since they
approximate the statistics of the uniform Haar ensemble. Despite their central role in …

Krylov complexity of many-body localization: Operator localization in Krylov basis

F Ballar Trigueros, CJ Lin - SciPost Physics, 2022 - scipost.org
We study the operator growth problem and its complexity in the many-body localization
(MBL) system from the Lanczos algorithm perspective. Using the Krylov basis, the operator …

Operator entanglement in local quantum circuits I: Chaotic dual-unitary circuits

B Bertini, P Kos, T Prosen - SciPost Physics, 2020 - scipost.org
The entanglement in operator space is a well established measure for the complexity of the
quantum many-body dynamics. In particular, that of local operators has recently been …
