Entanglement Holography in Quantum Phases via Twisted Rényi-N Correlators
Pablo Sala, Frank Pollmann, Masaki Oshikawa +1
We introduce a holographic framework for the entanglement Hamiltonian in symmetry-protected topological (SPT) phases with area-law entanglement, whose reduced density matrix $Ï\pr…
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…
