Bosonic String Amplitudes From Ribbon Graphs
Sam Christian, Ben Mazel, Yuchen Wang +2
We develop a method for numerically computing higher genus CFT correlators and string amplitudes based on Kontsevich's ribbon graph parametrization of the moduli space $\mathcal{M}…

Aspects of Propagator Sparsening in Lattice QCD
Sam Christian, William Detmold
In lattice field theory, field sparsening aims to replace quantum fields, or objects constructed from them, with approximations that preserve the appropriate symmetries and maintai…
