Gauge- and coordinate-invariant equations for two-component systems

Quantum Physics 2022-07-06 v1

Abstract

The Schr\"odinger-like equations for the marginal and conditional probability amplitudes resulting from the exact factorization of the wavefunction of a two-component system are derived in a form that is invariant to gauge and coordinate transformations. Coupled equations equivalent to the nonrelativistic Schr\"odinger equation of a molecule are derived as an example.
