Observation of partial and infinite-temperature thermalization induced by repeated measurements on a quantum hardware
Alessandro Santini, Andrea Solfanelli, Stefano Gherardini +1
On a quantum superconducting processor we observe partial and infinite-temperature thermalization induced by a sequence of repeated quantum projective measurements, interspersed by…
Villain model with long-range couplings
Guido Giachetti, Nicolo Defenu, Stefano Ruffo +1
The nearest-neighbor Villain, or periodic Gaussian, model is a useful tool to understand the physics of the topological defects of the two-dimensional nearest-neighbor model,…
Quantum heat engine with long-range advantages
Andrea Solfanelli, Guido Giachetti, Michele Campisi +2
The employment of long-range interactions in quantum devices provides a promising route towards enhancing their performance in quantum technology applications. Here, the presence o…
Spreading of a local excitation in a Quantum Hierarchical Model
Luca Capizzi, Guido Giachetti, Alessandro Santini +1
We study the dynamics of the quantum Dyson hierarchical model in its paramagnetic phase. An initial state made by a local excitation of the paramagnetic ground state is considered.…
Fractal nature of high-order time crystal phases
Guido Giachetti, Andrea Solfanelli, Lorenzo Correale +1
Discrete Floquet time crystals (DFTC) are characterized by the spontaneous breaking of the discrete time-translational invariance characteristic of Floquet driven systems. In analo…
Energy fluctuation relations and repeated quantum measurements
Stefano Gherardini, Lorenzo Buffoni, Guido Giachetti +2
In this review paper, we discuss the statistical description in non-equilibrium regimes of energy fluctuations originated by the interaction between a quantum system and a measurem…
transitions in classical and quantum long-range systems
Guido Giachetti, Andrea Trombettoni, Stefano Ruffo +1
In the past decades considerable efforts have been made in order to understand the critical features of both classical and quantum long-range interacting models. The case of the Be…
