Description
A nonperturbative definition of chiral gauge theories remains a long-standing open problem. Hamiltonian formulations, motivated in part by quantum simulation and tensor-network methods, offer a fresh perspective on old questions: fermion doubling and the fate of the Nielsen–Ninomiya theorem. Drawing on recent advances in our understanding of anomalies on the lattice, I will survey these developments and discuss the prospects and obstacles for gauging chiral symmetries in the Hamiltonian setting.
