Description
A Quantum Finite Element (QFE) Lagrangian is formulated for
a general simplicial complex approximation to a smooth Euclidean
Riemann manifold. The construction is applied to Wilson Dirac fermions
with the appropriate lattice spin connection and to phi 4th-theory
with QFE counter terms required for these theories to converge in the
continuum limit. Numerical tests are given for the Wilson-Fisher
fixed point in 2D with comparison to the exact solution of the Ising CFT on
the two sphere and for the 3D phi 4th-theory in radial quantization.
Potential future applications to more general 3D conformal field theories and 4D
Beyond the Standard Model (BSM) gauge theories near the conformal window are
suggested.
