Large- with long-range interactions: integrability and resonance dynamics
Guido Giachetti, Nicolo Defenu
We study the large- dynamics of the long-range quantum model, focusing on the strong long-range regime . The dynamics of the model exhibits non-trivial features on…
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…
Universal purification dynamics in real non-unitary quantum processes
Federico Gerbino, Donghoon Kim, Guido Giachetti +2
We study purification dynamics in monitored quantum processes governed by ensembles of quantum circuits in different random-matrix symmetry classes. We analyze the universal aspect…
One-dimensional long-range Ising model: two (almost) equivalent approximations
Valerio Pagni, Guido Giachetti, Andrea Trombettoni +1
We investigate the critical behavior of the one-dimensional Ising model with long-range interactions using the functional renormalization group in the local potential approximation…
Universality and weak-ergodicity breaking in quantum quenches
Guido Giachetti, Andrea Solfanelli, Nicolò Defenu
Understanding equilibration and universality after sudden quantum quenches remains a central challenge in isolated many-body systems. Persistent oscillations and anomalous scaling…
Field theory for monitored Brownian SYK clusters
Anastasiia Tiutiakina, Hugo Lóio, Guido Giachetti +2
We consider the time evolution of multiple clusters of Brownian Sachdev-Ye-Kitaev (SYK), i.e. systems of N Majorana fermions with a noisy interaction term. In addition to the unita…
