Interaction effects on 3D topological superconductors: surface topological order from vortex condensation, the 16 fold way and fermionic Kramers doublets
Max A. Metlitski, Lukasz Fidkowski, Xie Chen +1
Three dimensional topological superconductors with time reversal symmetry (class DIII) are indexed by an integer , the number of surface Majorana cones, according to the free fe…

Anomalous Symmetry Fractionalization and Surface Topological Order
Xie Chen, Fiona J. Burnell, Ashvin Vishwanath +1
In addition to possessing fractional statistics, anyon excitations of a 2D topologically ordered state can realize symmetry in distinct ways , leading to a variety of symmetry enri…

`Gauging' time reversal symmetry in tensor network states
Xie Chen, Ashvin Vishwanath
It is well known that unitary symmetries can be `gauged', i.e. defined to act in a local way, which leads to a corresponding gauge field. Gauging, for example, the charge conservat…
