Is the Schrodinger equation second order? In non-relativistic quantum mechanics, we have Schrödinger’s equation, which is first-order. But not every quantum particle is a fermion, and, AFAIK relativistic non-fermion particles obey the Klein-Gordon equation, which is second-order! Is the Schrodinger equation true? Consider the Schrödinger equation, which allows you to compute the “wave function” of […]
