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…
Phase Coherence of Strongly Interacting Bosons in One-Dimensional Optical Lattices
R. Vatré, G. Morettini, J. Beugnon +3
Ultracold Bose gases in one-dimensional optical lattices constitute an important benchmark problem in the study of strongly interacting many-body quantum phases. Here we present a…
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…
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…
