P. Holland, Constructing the electromagnetic field from trajectories



P. Holland, Computing the wavefunction from trajectories: particle and wave pictures in quantum mechanics and their relation

Ann. Phys. (NY) 315, 505-531 (2005)



2. De Broglie-Bohm theory and related studies


P. Holland, The Quantum Theory of Motion: An Account of the de Broglie-Bohm Causal Interpretation of Quantum Mechanics, 618 pp. (Cambridge University Press, 1993, reprinted 1995, 1997, 2000, 2004, Chinese edition 2000) ISBN 0 52148543 6.

The book was digitally reprinted in 2004 so is in print for eternity, according to the publisher. It can be purchased here or here (UK) and here (US) (where there are some reviews).

pdf preprint


P. Holland, What’s wrong with Einstein’s 1927 hidden-variable interpretation of quantum mechanics?

Found. Phys. 35, 177-196 (2005)


Includes a description of a ‘supernonlocal’ theory, i.e., a theory more nonlocal than quantum theory yet compatible with quantal predictions (originally presented in Found. Phys. 28, 881-911 (1998)).


P. Holland and C. Philippidis, Implications of Lorentz covariance for the guidance formula in two-slit quantum interference

Phys. Rev. A 67, 062105 (2003)


Contains plots of the trajectories in the two-slit experiment for electrons correcting previous plots that neglected spin effects.


P. Holland, Uniqueness of conserved currents in quantum mechanics

Ann. Phys. (Leipzig) 12, 446-462 (2003)

Nuovo Cimento B 116, 1143-1172 (2001)

pdf preprint


P. Holland, Testing wavefunction collapse (unpublished 1995 paper) pdf

Suggests using protective measurements to discriminate between epistemological and ontological interpretations of the wavefunction.
