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
Pak Kau Lim, Michael Mulligan, Jeffrey C. Y. Teo
We study bosonic topological phases constructed from electrons. In addition to a bulk excitation energy gap, these bosonic phases also have a fermion energy gap, below which all lo…
Dihedral twist liquid models from emergent Majorana fermions
Jeffrey C. Y. Teo, Yichen Hu
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…
Entanglement Entropy of Generalized Moore-Read Fractional Quantum Hall State Interfaces
Ramanjit Sohal, Bo Han, Luiz H. Santos +1
Topologically ordered phases of matter can be characterized by the presence of a universal, constant contribution to the entanglement entropy known as the topological entanglement…
Magnetic Effects on Topological Chiral Channels in Bilayer Graphene
Aaron Winn, John Maier, Andrew Jiao +1
We study the effect of a magnetic field on topological chiral channels of bilayer graphene at electric domain walls. The persistence of chiral edge states is attributed to the diff…
