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…

Chiral symmetry and Atiyah-Patodi-Singer index theorem for staggered fermions
Mendel Nguyen, Hersh Singh
We consider the Atiyah-Patodi-Singer (APS) index theorem corresponding to the chiral symmetry of a continuum formulation of staggered fermions called Kähler-Dirac fermions, which h…
