Resurrecting the coherent state variational algorithm for large N gauge theories

A bstract The feasibility of studying, numerically, properties of infinite volume QCD-like theories in the large N limit using coherent state variational methods is reassessed. An entirely new implementation of this approach is described, applicable to SU( N ) lattice gauge theories, with or without fundamental representation fermions, on cubic lattices of up to four dimensions. In addition to various test cases, initial results are presented for Hamiltonian Yang-Mills theory on an infinite two-dimensional spatial lattice.
