WebJul 11, 2024 · 2. The principle of least action says that a body moves in such a way that the action value S = ∫ L d t is stationary (often minimal). The principle is written as. δ S = 0 . In contrast, Schwinger's quantum action principle between an in and an out state is. o u t δ S i n = ℏ i δ o u t i n . In Schwingers approach, the action principle is targeted towards quantum mechanics. The action becomes a quantum action, i.e. an operator, . Although it is superficially different from the path integral formulation where the action is a classical function, the modern formulation of the two formalisms are identical. Suppose we have two states defined by the values of a complete set of commuting operators at t…
