Microscopic study of topological phase transitions: Percolation point of view
The study investigates how topological order changes during a phase transition due to quantum decoherence by focusing on topological entanglement and 1-form symmetry. It introduces quasi-local topological entanglement negativity (QLTEN) to describe decoherence percolation, revealing that these quantities act as first and zeroth simplicial homology objects whose transitions are governed by percolation patterns.
