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. D…
Lattice Regularization of Reduced Kähler-Dirac Fermions and Connections to Chiral Fermions
Simon Catterall
We show how a path integral for reduced Kähler-Dirac fermions suffers from a phase ambiguity associated with the fermion measure that is an analog of the measure problem seen for c…
Improved coarse-graining methods on two dimensional tensor networks including fermions
Muhammad Asaduzzaman, Simon Catterall, Yannick Meurice +2
We show how to apply renormalization group algorithms incorporating entanglement filtering methods and a loop optimization to a tensor network which includes Grassmann variables wh…
Report of the Snowmass 2021 Theory Frontier Topical Group on Quantum Information Science
Simon Catterall, Roni Harnik, Veronika E. Hubeny +12
We summarize current and future applications of quantum information science to theoretical high energy physics. Three main themes are identified and discussed; quantum simulation,…
