Observation of universal hierarchical relaxation in a quantum simulator
Jiaozi Wang, Manoj K. Joshi, Luca Capizzi +4
Autocorrelation functions play a key role in the theoretical characterization of the dynamical properties of interacting many-body quantum systems. Recently, bringing together the…
Emergent integrable dynamics in a non-integrable Rydberg-atom chain
Gianluca Morettini, Luca Capizzi, Leonardo Mazza +1
We show that integrable and non-integrable dynamics can coexist in the same Rydberg-atom chain, depending on the initial state in which the system is prepared. In the setting we co…
Observing weakly broken conservation laws in a dipolar Rydberg quantum spin chain
Cheng Chen, Luca Capizzi, Alice Marché +6
Integrable quantum many-body systems host families of extensive conservation laws, some of which are fragile: even infinitesimal perturbations can qualitatively alter their dynamic…
Ergodicity and hydrodynamics: from quantum to classical spin systems
Jiaozi Wang, Luca Capizzi, Dario Poletti +1
We show that in classical spin systems the precise nature of the late-time hydrodynamic tails of the autocorrelation functions of a generic observable is determined by (i) the dyna…
Universal properties of the many-body Lanczos algorithm at finite size
Luca Capizzi, Leonardo Mazza, Sara Murciano
We study the universal properties of the Lanczos algorithm applied to finite-size many-body quantum systems. Focusing on autocorrelation functions of local operators and on their i…
Transport in a System with a Tower of Quantum Many-Body Scars
Gianluca Morettini, Luca Capizzi, Maurizio Fagotti +1
We report the observation of unconventional transport phenomena in a spin-1 model that supports a tower of quantum many-body scars, and we discuss their properties uncovering their…
Exceptional stationary state in a dephasing many-body open quantum system
Alice Marché, Gianluca Morettini, Leonardo Mazza +2
We study a dephasing many-body open quantum system that hosts, together with the infinite-temperature state, another additional stationary state. The latter is exceptional in many…
Hydrodynamics and the eigenstate thermalization hypothesis
Luca Capizzi, Jiaozi Wang, Xiansong Xu +2
The eigenstate thermalization hypothesis (ETH) describes the properties of diagonal and off-diagonal matrix elements of local operators in the eigenenergy basis. In this work, we p…
Energy-filtered quantum states and the emergence of non-local correlations
Gianluca Morettini, Luca Capizzi, Maurizio Fagotti +1
Energy-filtered quantum states are promising candidates for efficiently simulating thermal states. We explore a protocol designed to transition a product state into an eigenstate l…
