We present a new solution of the paraxial equation based on the Pearcey function, which is related to the Airy function and describes diffraction about a cusp caustic. The Pearcey beam displays… (More)

A brief review is given of the continuous spontaneous localization (CSL ) model , in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the… (More)

We present a mathematical analysis of the finite-energy Airy beam with a sharply truncated spectrum, which can be generated by a uniformly illuminated, finite-sized spatial light modulator, or… (More)

A brief review is given of the Continuous Spontaneous Localization (CSL) model in which a classical field interacts with quantized particles to cause dynamical wavefunction collapse. One of the… (More)

The “measurement problem” can be thought of as indicating a serious flaw in the foundations of quantum theory[1], and therefore a potential clue to new physics. When a measurement is described by… (More)

We describe a new class of propagation-invariant light beams with Fourier transform given by an eigenfunction of the quantum mechanical pendulum. These beams, whose spectra (restricted to a circle)… (More)
