Abstract
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 consider the effect of gauge fluctuations using a simple model and find the behavior is not strongly modified. The results, distinct from conventional Mott insulator or band theory predictions, suggest that measuring the spectral function, e.g., via ARPES could help in the experimental verification and characterization of spin liquids.
