Entanglement negativity in decohered topological states
Kang-Le Cai, Meng Cheng
We investigate universal entanglement signatures of mixed-state phases obtained by decohering pure-state topological order (TO), focusing on topological corrections to logarithmic…
Anyonic membranes and Pontryagin statistics
Yitao Feng, Hanyu Xue, Yuyang Li +4
Anyons, unique to two spatial dimensions, underlie extraordinary phenomena such as the fractional quantum Hall effect, but their generalization to higher dimensions has remained el…
SO(n) Affleck-Kennedy-Lieb-Tasaki states as conformal boundary states of integrable SU(n) spin chains
Yueshui Zhang, Ying-Hai Wu, Meng Cheng +1
We construct a class of conformal boundary states in the Wess-Zumino-Witten (WZW) conformal field theory (CFT) using the symmetry embedding $\mathrm{Spin}(n)_2 \…
Ordering the topological order in the fractional quantum Hall effect
Meng Cheng, Seth Musser, Amir Raz +2
We discuss the possible topological order/topological quantum field theory of different quantum Hall systems. Given the value of the Hall conductivity, we constrain the global symm…
Boundary topological orders of (4+1)d fermionic SPT states
Meng Cheng, Juven Wang, Xinping Yang
We investigate (3+1)d topological orders in fermionic systems with an anomalous symmetry, where its subgroup is the fermi…
Sudden change in entanglement Hamiltonian: Phase diagram of an Ising entanglement Hamiltonian
Zhe Wang, Siyi Yang, Bin-Bin Mao +2
The form of the entanglement Hamiltonian varies with the parameters of the original system. Whether there is a singularity is the key problem for demonstrating/negating the univers…
Fractionalization as an alternate to charge ordering in electronic insulators
Seth Musser, Meng Cheng, T. Senthil
Incompressible insulating phases of electronic systems at partial filling of a lattice are often associated with charge ordering that breaks lattice symmetry. The resulting phases…
Topological holography, quantum criticality, and boundary states
Sheng-Jie Huang, Meng Cheng
Topological holography is a holographic principle that describes the generalized global symmetry of a local quantum system in terms of a topological order in one higher dimension.…
