A Tour of Variational Quantum Field Theory

Tuesday July 19, 2005 74 Jorgensen, Caltech

We discuss the general problems encountered when trying to apply the variational principle to quantum field theory. We look at different ways to get around these problems and argue that recent advances in applying MPS (matrix product states) to condensed matter theory might provide a good general purpose variational technique for quantum field theory.
