Why Bohm's Quantum Theory?

Abstract: In this paper the criticism to the Bohm's quantum theory has been discussed in the beginning. Then a formalism change of this theory from its original form to recent one is shown. The differences between the normal Copenhagen interpretation and that of Bohm's quantum theory are possible to be seen. Bohm's new idea and new terms such as implicate and explicate order, process, unfold and enfold are discussed to give an interpretation to the theory. This is also able to show that Bohm theory requests the radical change about our world-picture. Key words; Bohm theory, The implicate & explicate order, Quantum potential and Information.

In this article, a causal model on the basis of trajectory is introduced for description of quantum systems. This theory is structurally very similar to Bohme mechanics, and like Bohme theory reproduces all statistical consequences of standard quantum mechanics. Particle trajectories in this model are different from anticipated ones by Bohme model. Quantum potential (force) form, which is given, is different from Bohme theory. Actually, this model will convert to Bohme theory by annihilating the free parameter ( μ ). Theoretical properties of this model are investigated in the same way as Galilean invariance. Also, a precise comparison between this theory and Bohme mechanics is made, and some suggestions are presented (through transit time distribution) for experimental distinction between these two models. Finally, extension of this theory is investigated

It is conventionally believed that Bohm's quanturn theory yields all the predictions of standard quantum theory. However, in this paper, we show that the transmission and reflection coefficients (i.e., probabilities) predicted by Bohm's quanturn theory can be different from those predicted by standard quantum theory for energy eigenstates of the step barrier.
