De Broglie-Bohm Interpretation Research Articles

A quantum solution to a cosmological mystery

It is suggested that the quantum potential of the causal de Broglie-Bohm interpretation of quantum theory might cancel a large cosmological constant, and so explain the remarkably small observed value of this quantity.

Locality and nonlocality in correlated two-particle interferometry

By using the de Broglie-Bohm interpretation of quantum mechanics, we can explore the nature of nonlocality by modelling one of the recent nonlocally-correlated two-photon interferometry experiments. The system and its entangled wavefunction evolve deterministically with unique initial positions of the particles producing unique and locally determined system trajectories in configuration space. The individual particle motions in real space are obtainable from the system trajectories.

New twists to Einstein's two-slit experiment: complementarity vis-a-vis the causal interpretation

The authors consider the new adaptations of Einstein's two-slit experiment in terms of recently performed experiments with neutrons, and analyse them in the light of the complementarity principle. They contrast this with the description in terms of the de Broglie-Bohm causal interpretation.

Nonlocally correlated trajectories in two-particle quantum mechanics

In this paper we present a series of computer calculations carried out in order to demonstrate exactly how the de Broglie-Bohm interpretation works for two-particle quantum mechanics. In particular, we show how the de Broglie-Bohm interpretation can account for the essential features of nonrelativistic, two-particle quantum mechanics in terms of well-defined, correlated, individual particle trajectories and spin vectors. We demonstrate exactly how both quantum statistics and the correlations observed in Einstein-Podolsky-Rosen experiments can be explained in terms of nonlocal quantum potentials and nonlocal quantum torques which act on the well-defined individual particle coordinates and spin vectors.

Particle trajectories and interference in a time-dependent model of neutron single crystal interferometry

The de Broglie-Bohm interpretation of quantum mechanics is shown to provide an explanation of the observed spatial interference in neutron single crystal interferometers in terms of well-defined individual particle trajectories with continuously variable energy.
