Hey all, I'm not sure if this belonged in the physics or engineering forum, but here's the question: has quantum field theory been applied to any engineering disciplines yet? I know quantum mechanics has been used extensively in electrical engineering and materials science/engineering. I also know that many condensed matter physicists today use quantum field theory in it's non-relativistic limit. It seems to me that condensed matter physicists would use quantum field theory to create more accurate predictive models for device design, novel materials, etc. (things that they currently use QM for), but I haven't found any books or anything online about this. Thanks for your inputs!
