Ginsparg-Wilson Hamiltonians with Improved Chiral Symmetry
Hersh Singh
We construct a family of Ginsparg-Wilson Hamiltonians with improved chiral properties, starting from a construction of Creutz-Horvath-Neuberger that provides a doubler-free Hamilto…

Generalized Ginsparg-Wilson relations: Fermionic anomalies on the lattice
Hersh Singh
The Ginsparg-Wilson (GW) relation elegantly captures how the anomalous chiral symmetry of a Dirac fermion manifests on the lattice. In this talk, we discuss how the GW relation and…

Real-Time Simulation of Asymmetry Generation in Fermion-Bubble Collisions
Marcela Carena, Ying-Ying Li, Tong Ou +1
Motivated by the out-of-equilibrium dynamics during an early-universe first-order phase transition, we perform real-time simulations of fermion-bubble scattering in dimension…
