Exact many-body scars and their stability in constrained quantum chains
Federica Maria Surace, Matteo Votto, Eduardo Gonzalez Lazo +3
Quantum scars are non-thermal eigenstates characterized by low entanglement entropy, initially detected in systems subject to nearest-neighbor Rydberg blockade, the so called PXP m…
Weak-ergodicity-breaking via lattice supersymmetry
Federica Maria Surace, Giuliano Giudici, Marcello Dalmonte
We study the spectral properties of -dimensional supersymmetric lattice models. We find systematic departures from the eigenstate thermalization hypothesis (ETH) in the fo…
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…
