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 $ρ\pro…

Spontaneous Strong Symmetry Breaking in Open Systems: Purification Perspective
Pablo Sala, Sarang Gopalakrishnan, Masaki Oshikawa +1
We explore the landscape of the decoherence effect in mixed-state ensembles from a purification perspective. We analyze the spontaneous strong-to-weak symmetry breaking (SSSB) in m…
