Are atoms waves or particles?
Trevor W. Marshall
It is shown that the Kapitza-Dirac effect with atoms, which has been considered to be evidence of their wavelike character, can be interpreted as a scattering of pointlike objects…
Nonlocality - The party may be over
Trevor W. Marshall
We demonstrate that the phenomenon known as Spontaneous Parametric Down Conversion is really an amplification, in a nonlinear crystal pumped by a laser, of certain pairs of modes o…
A Local Hidden Variables Model for Experiments involving Photon Pairs Produced in Parametric Down Conversion
Alberto Casado, Trevor Marshall, Ramon Risco-Delgado +1
In previous articles we have developed a theory of down conversion in nonlinear crystals, based on the Wigner representation of the radiation field. Taking advantage of the fact th…
The zeropoint field - no longer a ghost
Trevor W. Marshall
We develop a local realist analysis of parametric down conversion, based on the recognition that the pump field, instead of down converting spontaneously, does so through its nonli…
A local realist theory of parametric down conversion
Trevor W. Marshall
In a series of articles we have shown that all parametric-down- conversion processes, both of type-I and type-II, may be described by a positive Wigner density. These results, toge…
Do we need photons in parametric down conversion?
Trevor W. Marshall
The phenomenon of parametric down conversion from the vacuum may be understood as a process in classical electrodynamics, in which a nonlinear crystal couples the modes of the pump…
