The Dual Dynamical Foundation of Orthodox Quantum Mechanics

Abstract:

In his groundbreaking The Mathematical Foundations of Quantum Mechanics von

Neumann asked the question, why quantum mechanics has a dual dynamics (unitary

evolution and collapse postulate)? He could not find a proper solution to it, i.e., a solution

based on dynamical principles. In this talk, we shall present such a solution, certified by the

golden rule of physics that the dynamics of a theory must follow from the action principle.

The reason why quantum mechanics has this “peculiar dual dynamics” is that the theory is

based, as we shall demonstrate, on a “peculiar” dual action.
