A Solution to the 1+1D Gauged Chiral Fermion Problem
Juven Wang, Xiao-Gang Wen
We show that the 3450 U(1) chiral fermion theory can appear as the low energy effective field theory of a 1+1D local lattice model, with an on-site U(1) symmetry and finite-range i…

Non-Perturbative Regularization of 1+1D Anomaly-Free Chiral Fermions and Bosons: On the equivalence of anomaly matching conditions and boundary gapping rules
Juven Wang, Xiao-Gang Wen
A non-perturbative lattice regularization of chiral fermions and bosons with anomaly-free symmetry in 1+1D spacetime is proposed. More precisely, we ask "whether there is a loc…
