WebFeb 11, 2015 · The formulation of quantum mechanics in terms of path integrals actually explains why equations of motion in classical mechanics can be derived from a variational principle. In the classical limit, that is, when the typical classical action is large with respect to \( \hbar\ ,\) the path integral can be evaluated by using the stationary phase ... WebApr 3, 2016 · We know the physical relevance of the classical limit of quantum mechanics quite well. However, if I take the classical limit of a quantum field theory, the answer is not so clear. Suppose I take the Hamiltonian for a free electron moving in one dimension, which is H ^ = p ^ 2 / 2 m.

WebAug 29, 2014 · The classical limit of quantum theories and quantum field theories is not straightforward. It is now a very active research topic in mathematical physics and analysis. The idea is simple: by its own construction, quantum mechanics should reduce to classical mechanics in the limit $\hslash\to 0$.
