Journal ArticleDOI
Lattice gauge theories and string dynamics in Rydberg atom quantum simulators
Federica Maria Surace,Federica Maria Surace,Paolo P. Mazza,Giuliano Giudici,Giuliano Giudici,Alessio Lerose,Andrea Gambassi,Marcello Dalmonte,Marcello Dalmonte +8 more
TL;DR: In this paper, it was shown that the constrained Hamiltonian dynamics induced by strong Rydberg interactions maps exactly onto the one of a U(1) lattice gauge theory and that the recently observed anomalously slow dynamics corresponds to a string-inversion mechanism, reminiscent of the string breaking typically observed in gauge theories.

Entanglement Hamiltonians of lattice models via the Bisognano-Wichmann theorem
Giuliano Giudici,Giuliano Giudici,Tiago Mendes-Santos,Pasquale Calabrese,Pasquale Calabrese,Marcello Dalmonte,Marcello Dalmonte +6 more
TL;DR: In this article, the authors provide a thorough investigation of entanglement Hamiltonians in lattice models obtained via the Bisognano-Wichmann theorem, which provides an explicit functional form for the entenglement Hamiltonian itself in quantum field theory.
Journal ArticleDOI
Exact many-body scars and their stability in constrained quantum chains
Federica Maria Surace,Matteo Votto,Matteo Votto,Eduardo Gonzalez Lazo,Alessandro Silva,Marcello Dalmonte,Giuliano Giudici +6 more
TL;DR: In this paper, the authors study the response of these exact quantum scars to perturbations by analyzing the scaling of the fidelity susceptibility with system size and find that some of them are anomalously stable at first order in perturbation theory, in sharp contrast to the eigenstate thermalization hypothesis.
Journal ArticleDOI
Entanglement-Guided Search for Parent Hamiltonians.
Xhek Turkeshi,Xhek Turkeshi,Tiago Mendes-Santos,Giuliano Giudici,Giuliano Giudici,Marcello Dalmonte,Marcello Dalmonte +6 more
TL;DR: The results show the entanglement structure of ground stateWave functions considerably simplifies the search for parent Hamiltonians, and correctly reconstructs the parent Hamiltonian correspondent to several nontrivial ground state wave functions.
