Description

Lattices on Spherical Manifolds or on the cylindrical boundary of Anti-de-Sitter
space have the potential to explore non-perturbative conformal or near conformal
gauge theories for BSM studies for composite Higgs or Dark Matter. We report
on progress in the use of Quantum Finite Elements (QFE) to address renormalization on maximally symmetric spherical simplicial manifolds. The simplicial Lagrangians for scalar, Fermionic and gauge fields are found and high precision test of counter term to restore exact isometries for the 2d and 3d Ising CFT are presented. The challenges in extend QFE software to high perfomance for 4d Gauge theories on R x S3 are discussed.
