Abstract:
We study a dephasing many-body open quantum system that hosts, together with the infinite-temperature 足球比分数据, another additional stationary 足球比分数据, that is associated with a nonextensive strong symmetry. This 足球比分数据, that is a pure dark 足球比分数据, is exceptional in that it retains memory of the initial condition, whereas any orthogonal 足球比分数据 evolves toward the infinite-temperature 足球比分数据 erasing any information on the initial 足球比分数据. We discuss the approach to stationarity of the model focusing in particular on the fate of interfaces between the two states, and we explain how the stationary-足球比分数据 manifold emerges from the algebraic properties of the local operators in the generator of the evolution. Moreover, we point out the reasons for considering these exceptional stationary states as quantum many-body scars in the open system framework.

Brief CV of Dr. Lorenzo Gotta:
Dr. Lorenzo Gotta obtained hid PhD at the University of Paris-Saclay in 2022, working mainly on pairing mechanisms leading to exotic phases of matter in one-dimensional quantum many-body systems. Afterwards, he moved to the University of Geneva to work as a postdoctoral research and teaching assistant in the group of Prof. Thierry Giamarchi, where his research specialized on the broad area of non-equilibrium quantum many-body dynamics, with a focus on quantum impurity dynamics, lack of thermalization through quantum many-body scars and dissipative quantum many-body systems.
