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…
Purification Timescales in Monitored Fermions
Hugo Lóio, Andrea De Luca, Jacopo De Nardis +1
We investigate the crucial role played by a global symmetry in the purification timescales and the phase transitions of monitored free fermionic systems separating a mixed and a pu…
