1+1d Lattice Dirac Fermions from Non-Onsite Vector and Axial Symmetries
Tabin Dharanikota, Lukasz Fidkowski
We construct an exactly solvable Hamiltonian lattice model realizing a 1+1d Dirac fermion, with exact microscopic vector and axial vector symmetries. The mixed anomaly betwe…

Chiral Lattice Gauge Theories from Symmetry Disentanglers
Ryan Thorngren, John Preskill, Lukasz Fidkowski
We propose a Hamiltonian framework for constructing chiral gauge theories on the lattice based on symmetry disentanglers: constant-depth circuits of local unitaries that transform…

Non-invertible bosonic chiral symmetry on the lattice
Lukasz Fidkowski, Cenke Xu, Carolyn Zhang
In this work we realize the 3 + 1 dimensional non-invertible chiral symmetry generator as an operator in a many body lattice Hilbert space. A crucial ingredient in…
