Hi,(adsbygoogle = window.adsbygoogle || []).push({});

Is it meaningful to inquire about the classical limit of a quantum field theory? Specifically, is it possible to formally recover NRQM and RQM from quantum field theory? I am told this is a wrong/ill-posed question, so I wanted to get a clearer idea about it...after all, in a QM course, the classical limit of Schrodinger's equation is shown as the Hamilton Jacobi equation. Are there any analogues in QFT?

Sorry if this is a wrong question to ask, but in that case, I would appreciate being corrected. :-)

Thanks in advance.
