Long-time divergences in the nonlinear response of gapped one-dimensional many-particle systems
M. Fava, S. Gopalakrishnan, R. Vasseur +2
We consider one dimensional many-particle systems that exhibit kinematically protected single-particle excitations over their ground states. We show that momentum and time-resolved…
Anomalous thermal relaxation and pump-probe spectroscopy of 2D topologically ordered systems
Max McGinley, Michele Fava, S. A. Parameswaran
We study the behaviour of linear and nonlinear spectroscopic quantities in two-dimensional topologically ordered systems, which host anyonic excitations exhibiting fractional stati…
Designs via Free Probability
Michele Fava, Jorge Kurchan, Silvia Pappalardi
Unitary Designs have become a vital tool for investigating pseudorandomness since they approximate the statistics of the uniform Haar ensemble. Despite their central role in quantu…
Nonlinear sigma models for monitored dynamics of free fermions
Michele Fava, Lorenzo Piroli, Tobias Swann +2
We derive field theory descriptions for measurement-induced phase transitions in free fermion systems. We focus on a multi-flavor Majorana chain, undergoing Hamiltonian evolution w…
Shadow tomography from emergent state designs in analog quantum simulators
Max McGinley, Michele Fava
We introduce a method that allows one to infer many properties of a quantum state -- including nonlinear functions such as Rényi entropies -- using only global control over the con…
Signatures of fractional statistics in nonlinear pump-probe spectroscopy
Max McGinley, Michele Fava, S. A. Parameswaran
We show that the presence of anyons in the excitation spectrum of a two-dimensional system can be inferred from nonlinear spectroscopic quantities. In particular, we consider pump-…
Multiversality and Unnecessary Criticality in One Dimension
Abhishodh Prakash, Michele Fava, S. A. Parameswaran
We present microscopic models of spin ladders which exhibit continuous critical surfaces whose properties and existence, unusually, cannot be inferred from those of the flanking ph…
Divergent nonlinear response from quasiparticle interactions
Michele Fava, Sarang Gopalakrishnan, Romain Vasseur +2
We demonstrate that nonlinear response functions in many-body systems carry a sharp signature of interactions between gapped low-energy quasiparticles. Such interactions are challe…
Weak ergodicity breaking in Josephson-junction arrays
Angelo Russomanno, Michele Fava, Rosario Fazio
We study the quantum dynamics of Josephson junction arrays. We find isolated groups of low-entanglement eigenstates, that persist even when the Josephson interaction is strong enou…
Hydrodynamic non-linear response of interacting integrable systems
Michele Fava, Sounak Biswas, Sarang Gopalakrishnan +2
We develop a formalism for computing the non-linear response of interacting integrable systems. Our results are asymptotically exact in the hydrodynamic limit where perturbing fiel…
Chaos and subdiffusion in the infinite-range coupled quantum kicked rotors
Angelo Russomanno, Michele Fava, Rosario Fazio
We map the infinite-range coupled quantum kicked rotors over an infinite-range coupled interacting bosonic model. In this way we can apply exact diagonalization up to quite large s…
Quantum chaos and ensemble inequivalence of quantum long-range Ising chains
Angelo Russomanno, Michele Fava, Markus Heyl
We use large-scale exact diagonalization to study the quantum Ising chain in a transverse field with long-range power-law interactions decaying with exponent . We numerically st…
Non-ergodic behaviour of clean Bose-Hubbard chains
Angelo Russomanno, Michele Fava, Rosario Fazio
We study ergodicity breaking in the clean Bose-Hubbard chain for small hopping strength. We see the existence of a non-ergodic regime by means of indicators as the half-chain entan…
Spin crossovers and superdiffusion in the one-dimensional Hubbard model
Michele Fava, Brayden Ware, Sarang Gopalakrishnan +2
We use tools from integrability and generalized hydrodynamics to study finite-temperature dynamics in the one-dimensional Hubbard model. First, we examine charge, spin, and energy…
Glide symmetry breaking and Ising criticality in the quasi-1D magnet CoNbO
Michele Fava, Radu Coldea, S. A. Parameswaran
We construct a microscopic spin-exchange Hamiltonian for the quasi-1D Ising magnet CoNbO that captures detailed and hitherto-unexplained aspects of its dynamic spin structu…
Many-body dynamical localization in the kicked Bose-Hubbard chain
Michele Fava, Rosario Fazio, Angelo Russomanno
We provide evidence that a clean kicked Bose-Hubbard model exhibits a many-body dynamically localized phase. This phase shows ergodicity breaking up to the largest sizes we were ab…
