Anomalous Crystal Symmetry Fractionalization on the Surface of Topological Crystalline Insulators
The surface of a three-dimensional topological electron system often hosts symmetry-protected gapless surface states. With the effect of electron interactions, these surface states can be gapped out without symmetry breaking by a surface topological order, in which the anyon excitations carry anomal...
