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…
The myth of the down converted photon
Trevor W. Marshall
Parametric down conversion (PDC) is widely interpreted in terms of photons, but, even among supporters of this interpretation, many properties of the photon pairs have been describ…
