The de Broglie–Bohm theory describes the physics in the Bell test experiments as follows: to understand the evolution of the particles, we need to set up a wave equation for both particles; the orientation of the apparatus affects the wavefunction. The particles in the experiment follow the guidance of the wavefunction.
In the framework of the de Broglie–Bohm theory, the quantum potential is a term within the Schrödinger equation which acts to guide the movement of quantum particles. . The quantum potential approach introduced by Bohm [1] [2] provides a physically less fundamental exposition of the idea presented by Louis de Broglie: de Broglie had postulated in 1925 that the relativistic wave function ...
David Joseph Bohm FRS [1] (/ b oʊ m /; 20 December 1917 – 27 October 1992) was an American scientist who has been described as one of the most significant theoretical physicists of the 20th century [2] and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind.
Bohm, his co-worker Basil Hiley, and other physicists of Birkbeck College worked toward a model of quantum physics in which the implicate order is represented in the form of an appropriate algebra or other pregeometry. They considered spacetime itself as part of an explicate order that is connected to an implicate order that they called pre-space.
Nowadays Bohm's theory is considered to be one of many interpretations of quantum mechanics. Some consider it the simplest theory to explain quantum phenomena. [33] Nevertheless, it is a hidden-variable theory, and necessarily so. [34] The major reference for Bohm's theory today is his book with Basil Hiley, published posthumously. [35]
The De Broglie-Bohm theory, also known as Bohmian mechanics or pilot wave theory, postulates, in addition to the wave function, an actual configuration of particles that exists even when unobserved. This particle configuration evolves in time according to a deterministic law, with the wave function guiding the motion of the particles.
Peter R. Holland is an English theoretical physicist, known for his work on foundational problems in quantum physics and in particular his book on the pilot wave theory and the de Broglie-Bohm causal interpretation of quantum mechanics. Holland was educated at Hazelwick Comprehensive School in Crawley, West Sussex and at Imperial College.
The relevance of quantum non-equilibrium states to physics lies in the fact that they can lead to different predictions for results of experiments, depending on whether the De Broglie–Bohm theory in its stochastic form or the Copenhagen interpretation is assumed to describe reality.
