Chiral Phases on the Lattice
Michael Austin DeMarco
While chiral quantum field theories (QFTs) describe a wide range of physical systems, from the standard model to topological quantum matter, the realization of chiral QFTs on a lat…
A Commuting Projector Model with a Non-zero Quantized Hall conductance
Michael DeMarco, Xiao-Gang Wen
By ungauging a recently discovered lattice rotor model for Chern-Simons theory, we create an exactly soluble path integral on spacetime lattice for Symmetry Protected Topo…
Lattice realization of compact Chern-Simons theory with exact 1-symmetries
Michael DeMarco, Xiao-Gang Wen
We propose a bosonic rotor model on a three dimensional space-time lattice. With the inclusion of a Maxwell term, we show that the low-energy semi-classical behavior of our…
A Single Right-Moving Free Fermion Mode on an Ultra-Local d Spacetime Lattice
Michael DeMarco, Xiao-Gang Wen
Defining a Chiral Fermion Theory on a lattice has presented an ongoing challenge both in Condensed Matter physics and in Lattice Gauge Theory. In this paper, we demonstrate that a…
A Novel Non-Perturbative Lattice Regularization of an Anomaly-Free Chiral Gauge Theory
Michael DeMarco, Xiao-Gang Wen
We present a numerical treatment of a novel non-perturbative lattice regularization of a Chiral Gauge Theory. Our approach follows recent proposals that exploit the…
