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…
