Fig. 1: Schematic of our proposal.
From: Diagnosing strong-to-weak symmetry breaking via Wightman correlators
We present a schematic of our proposal for using the Wightman correlator to diagnose strong-to-weak symmetry breaking of the density matrix. The strong symmetry of the density matrix is mapped onto the doubled symmetry of the thermofield double state, with each symmetry acting individually on the physical and auxiliary subsystems.
