  In the non-minimal Bohm  theory[18],  the behavior of an N-particle system is determined by its wave function and the intrinsic properties of the particles. But, in contrast to the minimal theory, in the non-minimal theory spins are intrinsic properties of particles. The wave function always evolves according to the Schrödinger equation, and it is interpreted as a ‘quantum field’ (which has no sources or any dependence on the particles). The quantum field guides the particles via the ‘quantum potential,’ an entity which is determined from the quantum field, and the evolution of properties is fully  deterministic.[19]
