Measures of Chirality in Mixed-State Topological Phases
Shijun Sun, Bader Aldossari, Rasmit Devkota +1
What does it mean for a mixed-state topological phase to be chiral? Mathematically, chirality can be sharply characterized through the symmetry algebra of the mixed state. Physical…

Holographic View of Mixed-State Symmetry-Protected Topological Phases in Open Quantum Systems
Shijun Sun, Jian-Hao Zhang, Zhen Bi +1
We establish a holographic duality between d-dimensional mixed-state symmetry-protected topological phases (mSPTs) and (d+1)-dimensional subsystem symmetry-protected topological st…
