Local diagnostics for strong-to-weak spontaneous symmetry breaking and non-equilibrium phase transitions
Carolyn Zhang
We construct strongly -symmetric local Markov/Lindblad dynamics exhibiting transitions between strong-paramagnetic behavior and strong-to-weak spontaneous symmetry br…

Translation symmetry-enforced long-range entanglement in mixed states
Ryan Thorngren, Lei Gioia, Carolyn Zhang
We show by a counting argument that even though translation symmetry admits symmetric short-range entangled (SRE) eigenstates, there are not enough such SRE eigenstates to span the…

Anomalies of Non-Invertible Symmetries in (3+1)d
Clay Cordova, Po-Shen Hsin, Carolyn Zhang
Anomalies of global symmetries are important tools for understanding the dynamics of quantum systems. We investigate anomalies of non-invertible symmetries in 3+1d using 4+1d bulk…
