Gravitational Lorentz anomaly from the overlap formula in 2-dimensions
arXiv:hep-th/9501012 · doi:10.1103/PhysRevD.51.R6617
Abstract
In this letter we show that the overlap formulation of chiral gauge theories correctly reproduces the gravitational Lorentz anomaly in 2-dimensions. This formulation has been recently suggested as a solution to the fermion doubling problem on the lattice. The well known response to general coordinate transformations of the effective action of Weyl fermions coupled to gravity in 2-dimensions can also be recovered.
