Variational Neural and Tensor Network Approximations of Thermal States
Sirui Lu, Giacomo Giudice, J. Ignacio Cirac
We introduce a variational Monte Carlo algorithm for approximating finite-temperature quantum many-body systems, based on the minimization of a modified free energy. This approach…
Trimer states with topological order in Rydberg atom arrays
Giacomo Giudice, Federica Maria Surace, Hannes Pichler +1
Trimers are defined as two adjacent edges on a graph. We study the quantum states obtained as equal-weight superpositions of all trimer coverings of a lattice, with the constraint…
Temporal entanglement, quasiparticles and the role of interactions
Giacomo Giudice, Giuliano Giudici, Michael Sonner +4
In quantum many-body dynamics admitting a description in terms of non-interacting quasiparticles, the Feynman-Vernon influence matrix (IM), encoding the effect of the system on the…
Rényi free energy and variational approximations to thermal states
Giacomo Giudice, Aslı Çakan, J. Ignacio Cirac +1
We propose the construction of thermodynamic ensembles that minimize the Rényi free energy, as an alternative to Gibbs states. For large systems, the local properties of these Rény…
Quantum East model: localization, non-thermal eigenstates and slow dynamics
Nicola Pancotti, Giacomo Giudice, J. Ignacio Cirac +2
We study in detail the properties of the quantum East model, an interacting quantum spin chain inspired by simple kinetically-constrained models of classical glasses. Through a com…
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…
A Nonequilibrium quantum phase transition in strongly coupled spin chains
Eduardo Mascarenhas, Giacomo Giudice, Vincenzo Savona
We study spin transport in a boundary driven XXZ spin chain. Driving at the chain boundaries is modeled by two additional spin chains prepared in oppositely polarized states. Emerg…
