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 m…
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…
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…
Measurement-Induced Phase Transition in State Estimation of Chaotic Systems and the Directed Polymer
Federico Gerbino, Guido Giachetti, Pierre Le Doussal +1
We introduce a solvable model of a measurement-induced phase transition (MIPT) in a deterministic but chaotic dynamical system with a positive Lyapunov exponent. In this setup, an…
