Macroscopic fluctuation theory of stochastic systems undergoing monitoring
João Costa, Pedro Ribeiro, Andrea De Luca
We develop a macroscopic fluctuation theory for diffusive classical lattice gases subject to continuous coarse-grained monitoring. Treating measurements in the typical-outcome (que…
Bayesian Monitoring of a Diffusive Particle in One Dimension
Federico Gerbino, Guido Giachetti, Pierre Le Doussal +1
We study the Bayesian monitoring of a single particle diffusing along a line, while an observer tracks it continuously using noisy measurements at each spatial point. The average S…
Observation of Universal Quantum Chaos at Shallow Depths
Arman Sauliere, Guglielmo Lami, Hugo Lóio +5
Universal statistical laws are a hallmark of quantum chaos. A natural route to probing them in quantum circuits is offered by the statistics of output probabilities, which for suff…
Implementation of quantum gates by Floquet analysis of kicked quantum system
Andrea De Luca, Carola Ciaramelletti, Simone Paganelli
Precise control of multi-qubit architectures remains a critical bottleneck in superconducting quantum processors. In this work, we investigate the synthesis of high-fidelity quantu…
Error-Correction Transitions in Finite-Depth Quantum Channels
Arman Sauliere, Guglielmo Lami, Pedro Ribeiro +2
We study error correction type protocols in which a quantum channel encodes logical information into an enlarged Hilbert space. Specifically, we consider channels realized by one d…
Emergence of universality in transport of noisy free fermions
João Costa, Pedro Ribeiro, Andrea De Luca
We analyze the effects of various forms of noise on one-dimensional systems of non-interacting fermions. In the strong noise limit, we demonstrate, under mild assumptions, that the…
Quantum Mpemba Effect in Random Circuits
Xhek Turkeshi, Pasquale Calabrese, Andrea De Luca
The essence of the Mpemba effect is that non-equilibrium systems may relax faster the further they are from their equilibrium configuration. In the quantum realm, this phenomenon a…
Universal distributions of overlaps from generic dynamics in quantum many-body systems
Alexios Christopoulos, Amos Chan, Andrea De Luca
We study the distribution of overlaps with the computational basis of a quantum state generated under generic quantum many-body chaotic dynamics, without conserved quantities, for…
Projected state ensemble of a generic model of many-body quantum chaos
Amos Chan, Andrea De Luca
The projected ensemble is based on the study of the quantum state of a subsystem conditioned on projective measurements in its complement. Recent studies have observed that a m…
A Dyson Brownian motion model for weak measurements in chaotic quantum systems
Federico Gerbino, Pierre Le Doussal, Guido Giachetti +1
We consider a toy model for the study of monitored dynamics in a many-body quantum systems. We study the stochastic Schrodinger equation resulting from the continuous monitoring wi…
Universality classes for purification in nonunitary quantum processes
Andrea De Luca, Chunxiao Liu, Adam Nahum +1
We consider universal aspects of two problems: (i) the slow purification of a large number of qubits by repeated quantum measurements, and (ii) the singular value structure of a pr…
Dual symplectic classical circuits: An exactly solvable model of many-body chaos
Alexios Christopoulos, Andrea De Luca, D L Kovrizhin +1
We propose a general exact method of calculating dynamical correlation functions in dual symplectic brick-wall circuits in one dimension. These are deterministic classical many-bod…
Elusive phase transition in the replica limit of monitored systems
Guido Giachetti, Andrea De Luca
We study an exactly solvable model of monitored dynamics in a system of spin- particles with pairwise all-to-all noisy interactions, where each spin is continuously weakly…
Frame potential of Brownian SYK model of Majorana and Dirac fermions
Anastasiia Tiutiakina, Andrea De Luca, Jacopo De Nardis
We consider the Brownian SYK, i.e. a system of Majorana (Dirac) fermions with a white-noise -body interaction term. We focus on the dynamics of the Frame potentials, a measu…

We study spectral and steady-state properties of generic Markovian dissipative systems described by quadratic fermionic Liouvillian operators of the Lindblad form. The Hamiltonian…
Darcy's law of yield stress fluids on a treelike network
Vincenzo Maria Schimmenti, Federico Lanza, Alex Hansen +4
Understanding the flow of yield stress fluids in porous media is a major challenge. In particular, experiments and extensive numerical simulations report a non-linear Darcy law as…
Generalized Deep Thermalization for Free Fermions
Maxime Lucas, Lorenzo Piroli, Jacopo De Nardis +1
In non-interacting isolated quantum systems out of equilibrium, local subsystems typically relax to non-thermal stationary states. In the standard framework, information on the res…
Many-body quantum chaos and emergence of Ginibre ensemble
Saumya Shivam, Andrea De Luca, David A. Huse +1
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 be…

Alexios Christopoulos, Pierre Le Doussal, Denis Bernard +1
We consider critical one dimensional quantum systems initially prepared in their groundstate and perturbed by a smooth noise coupled to the energy density. By using conformal field…
Discrete time-crystalline response stabilized by domain-wall confinement
Mario Collura, Andrea De Luca, Davide Rossini +1
Discrete time crystals represent a paradigmatic nonequilibrium phase of periodically driven matter. Protecting its emergent spatiotemporal order necessitates a mechanism that hinde…
