Low-energy behavior of spin-liquid electron spectral functions
Evelyn Tang, Matthew P. A. Fisher, Patrick A. Lee
We calculate the electron spectral function for a spin-liquid with a spinon Fermi surface and a Dirac spin-liquid. Calculations are based upon the slave-rotor mean-field theory. We…

Interaction effects on 1D fermionic symmetry protected topological phases
Evelyn Tang, Xiao-Gang Wen
In free fermion systems with given symmetry and dimension, the possible topological phases are labeled by elements of only three types of Abelian groups, Z_1, Z_2, or Z. For exampl…
