Nonperturbative calculation of symmetry breaking in quantum field theory
Carl M. Bender, Kimball A. Milton
A new version of the delta expansion is presented, which, unlike the conventional delta expansion, can be used to do nonperturbative calculations in a self-interacting scalar quant…

Multiple-Scale Analysis of Quantum Systems
Carl M. Bender, Luis M. A. Bettencourt
Conventional weak-coupling Rayleigh-Schrödinger perturbation theory suffers from problems that arise from resonant coupling of successive orders in the perturbation series. Multipl…
