Lorentzian Kähler-Dirac fermions
Simon Catterall, Jay Hubisz
We examine the formulation of Kähler fermions on spacetimes with Lorentz signature. In practice we focus on Minkowski spacetime since most of the difficulties that are encountered…

Gauging staggered fermion shift symmetries
Simon Catterall, Arnab Pradhan
Staggered fermion shift symmetries correspond to translations of the fermion field within the unit cell of a hypercubic lattice. They satisfy an algebra and in four Euclidean dimen…

Fermions, quantum gravity and holography in two dimensions
Muhammad Asaduzzaman, Simon Catterall, Abhishek Samlodia
We study a model comprising flavors of Kähler Dirac fermion propagating on a triangulated two dimensional disk which is constrained to have a negative average bulk curvature.…
