Symmetry Enforced Non-Abelian Topological Order at the Surface of a Topological Insulator
Xie Chen, Lukasz Fidkowski, Ashvin Vishwanath
The surfaces of three dimensional topological insulators (3D TIs) are generally described as Dirac metals, with a single Dirac cone. It was previously believed that a gapped surfac…
Non-Abelian Topological Order on the Surface of a 3D Topological Superconductor from an Exactly Solved Model
Lukasz Fidkowski, Xie Chen, Ashvin Vishwanath
Three dimensional topological superconductors (TScs) protected by time reversal (T) symmetry are characterized by gapless Majorana cones on their surface. Free fermion phases with…
Symmetry Protected Quantum State Renormalization
Ching-Yu Huang, Xie Chen, Feng-Li Lin
Symmetry protected topological (SPT) phases with gapless edge excitations have been shown to exist in principle in strongly interacting bosonic/fermionic systems and it is highly d…
Exactly Soluble Model of a 3D Symmetry Protected Topological Phase of Bosons with Surface Topological Order
F. J. Burnell, Xie Chen, Lukasz Fidkowski +1
We construct an exactly soluble Hamiltonian on the D=3 cubic lattice, whose ground state is a topological phase of bosons protected by time reversal symmetry, i.e a symmetry protec…
