Magnetic Resonance Based Proof of Reality of Wavefunction

Abstract

In this contribution, we use the formalism of Magnetic Resonance to present an argument for the reality of the solution of the Schrodinger Equation appropriate for the existence of Bloch Equation magnetization states. We take as our definition of Reality that the observable used can be measured in the laboratory such as the Cartesian x Component of Magnetization. We relate this real existing observable to the Density Matrix corresponding to the system and then argue the Density Matrix must have Physical Reality if the Magnetization has Physical Reality. Since the Density Matrix for a pure state is simply related to the wave function, we then argue that the corresponding wavefunction must also be Physically Real.
