Breakdown of ergodicity in disordered U(1) lattice gauge theories
Giuliano Giudici, Federica Maria Surace, Joel Etaya Ebot +2
We show how U(1) lattice gauge theories display key signatures of ergodicity breaking in the presence of a random charge background. Contrary to the widely studied case of spin mod…
Tunneling in projective quantum Monte Carlo simulations with guiding wave functions
T. Parolini, E. M. Inack, G. Giudici +1
Quantum tunneling is a valuable resource exploited by quantum annealers to solve complex optimization problems. Tunneling events also occur during projective quantum Monte Carlo (P…
Entanglement Hamiltonian of quantum critical chains and conformal field theories
T. Mendes-Santos, G. Giudici, M. Dalmonte +1
We consider a lattice version of the Bisognano-Wichmann (BW) modular Hamiltonian as an ansatz for the bipartite entanglement Hamiltonian of the quantum critical chains. Using numer…
Measuring von Neumann entanglement entropies without wave functions
T. Mendes-Santos, G. Giudici, R. Fazio +1
We present a method to measure the von Neumann entanglement entropy of ground states of quantum many-body systems which does not require access to the system wave function. The tec…
Lattice gauge theories and string dynamics in Rydberg atom quantum simulators
Federica M. Surace, Paolo P. Mazza, Giuliano Giudici +3
Gauge theories are the cornerstone of our understanding of fundamental interactions among particles. Their properties are often probed in dynamical experiments, such as those perfo…
Diagnosing Potts criticality and two-stage melting in one-dimensional hard-boson models
Giuliano Giudici, Adriano Angelone, Giuseppe Magnifico +4
We investigate a model of hard-core bosons with infinitely repulsive nearest- and next-nearest-neighbor interactions in one dimension, introduced by Fendley, Sengupta and Sachdev i…
