Random quantum circuits

MPA Fisher, V Khemani, A Nahum… - Annual Review of …, 2023 - annualreviews.org
Quantum circuits—built from local unitary gates and local measurements—are a new
playground for quantum many-body physics and a tractable setting to explore universal …

Microscopic origin of the quantum Mpemba effect in integrable systems

C Rylands, K Klobas, F Ares, P Calabrese… - Physical Review Letters, 2024 - APS
The highly complicated nature of far from equilibrium systems can lead to a complete
breakdown of the physical intuition developed in equilibrium. A famous example of this is the …

Generalized-hydrodynamic approach to inhomogeneous quenches: correlations, entanglement and quantum effects

V Alba, B Bertini, M Fagotti, L Piroli… - Journal of Statistical …, 2021 - iopscience.iop.org
We give a pedagogical introduction to the generalized hydrodynamic approach to
inhomogeneous quenches in integrable many-body quantum systems. We review recent …

Nonequilibrium full counting statistics and symmetry-resolved entanglement from space-time duality

B Bertini, P Calabrese, M Collura, K Klobas… - Physical Review Letters, 2023 - APS
Owing to its probabilistic nature, a measurement process in quantum mechanics produces a
distribution of possible outcomes. This distribution—or its Fourier transform known as full …

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 …

Efficient method for quantum impurity problems out of equilibrium

J Thoenniss, M Sonner, A Lerose, DA Abanin - Physical Review B, 2023 - APS
We introduce an efficient method to simulate the dynamics of an interacting quantum
impurity coupled to noninteracting fermionic reservoirs. Viewing the impurity as an open …

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
Rényi entropies are conceptually valuable and experimentally relevant generalizations of
the celebrated von Neumann entanglement entropy. After a quantum quench in a clean …

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 …
