An analog of topological entanglement entropy for mixed states
Ting-Tung Wang, Menghan Song, Zi Yang Meng +1
We propose the convex-roof extension of quantum conditional mutual information ("co(QCMI)") as a diagnostic of topological order in a mixed state. We focus primarily on topological…

Emergent Conformal Symmetry at the Multicritical Point of (2+1)D SO(5) Model with Wess-Zumino-Witten Term on Sphere
Bin-Bin Chen, Xu Zhang, Zi Yang Meng
Novel critical phenomena beyond the Landau-Ginzburg-Wilson paradigm have been long sought after. Among many candidate scenarios, the deconfined quantum critical point (DQCP) consti…
