Revisiting Canonical Quantization

Original · EN

Conventional canonical quantization procedures directly link various c-number and q-number quantities. Here, we advocate a different association of classical and quantum quantities that renders classical theory a natural subset of quantum theory with ℏ>0, in conformity with the real world wherein nature has chosen ℏ>0 rather than ℏ=0. While keeping the good results of conventional procedures, some examples are presented for which the new procedures offer better results than conventional ones.
