Entanglement cost hierarchies in quantum fragmented mixed states
Subhayan Sahu, Yahui Li, Pablo Sala
Strong symmetries enforce non-trivial quantum entanglement patterns on the stationary states of symmetric open quantum dynamics. Specifically, non-commuting conserved quantities le…
Dynamics in the presence of local symmetry-breaking impurities
Yahui Li, Pablo Sala, Frank Pollmann +2
Continuous symmetries lead to universal slow relaxation of correlation functions in quantum many-body systems. In this work, we study how local symmetry-breaking impurities affect…
Highly entangled stationary states from strong symmetries
Yahui Li, Frank Pollmann, Nicholas Read +1
We find that the presence of strong non-Abelian conserved quantities can lead to highly entangled stationary states even for unital quantum channels. We derive exact expressions fo…
Hilbert Space Fragmentation in Open Quantum Systems
Yahui Li, Pablo Sala, Frank Pollmann
We investigate the phenomenon of Hilbert space fragmentation (HSF) in open quantum systems and find that it can stabilize highly entangled steady states. For concreteness, we consi…
Driving Driven Lattice Gases to Identify Their Universality Classes
Yahui Li, Zhongda Zeng, Fan Zhong
The critical behavior of driven lattice gas models has been studied for decades as a paradigm to explore nonequilibrium phase transitions and critical phenomena. However, there exi…
