Constructing Quantum Field Theories Non-perturbatively with Hamiltonian Methods

Download to your calendar using vCal

If you have a question about this talk, please contact David Marsh .

While path integral approach to quantum field theories has come to dominate the field, the Hamiltonian methods have been unjustly neglected. I will discuss some work, inspired by the Rayleigh-Ritz method in quantum mechanics, which uses the Hamiltonian approach to do approximate but precise non-perturbative computations in strongly coupled quantum field theory in 1+1 dimensions.
