Modal field theory and quasi-sparse eigenvector diagonalization
Dean Lee
We review recent developments in non-perturbative field theory using modal field methods. We discuss Monte Carlo results as well as a new diagonalization technique known as the qua…

Singularities of massless planar diagrams, large-N_c mesons in 3+1 dimensions, and the 't Hooft model
Dean Lee
We study the singular Landau surfaces of planar diagrams contributing to scattering of a massless quark and antiquark in 3+1 dimensions. In particular, we look at singularities whi…
