Topological orders with classical Lie group symmetries from coupling electron wires
Pak Kau Lim, Michael Mulligan, Jeffrey C. Y. Teo
We study the topological order that arises from chiral states with or edge-state symmetry. This extends our previous study of topological orders that de…
Partial fillings of the bosonic quantum Hall state

We present a family of electron-based coupled-wire models of bosonic orbifold topological phases, referred to as twist liquids, in two spatial dimensions. All local fermion degrees…
Disentangling (2+1)d Topological States of Matter with the Entanglement Negativity
Pak Kau Lim, Hamed Asasi, Jeffrey C. Y. Teo +1
We use the entanglement negativity, a bipartite measure of entanglement in mixed quantum states, to study how multipartite entanglement constrains the real-space structure of the g…

The issue on the effect of interactions in topological states concerns not only interacting topological phases but also novel symmetry-breaking phases and phase transitions. Here w…
