Recently we have discussed a new approach to the problem of quantum gravity in which mechanical structures that are traditionally fixed, such as Fubini-Study metric Hilbert space states, become dynamical and so implement idea gravitizing quantum. In this paper elaborate on specific test using triple interference varying gravitational field. Our discussion is driven by profound analogy with rece...

The Talbot interferometer has been shown earlier to act as an optical tapped delay-line in the time domain. The interferometer is based on the self-imaging effect. It consists of two gratings separated by a multiple of the self-imaging distance. Here, we determine its temporal behaviour experimentally. First, the impulse response is measured directly in the time domain by means of femtosecond p...

X-ray imaging is of paramount importance for clinical and preclinical imaging but it is fundamentally restricted by the attenuation-based contrast mechanism, which has remained essentially the same since Roentgen's discovery a century ago. Recently, based on the Talbot effect, groundbreaking work was reported using 1D gratings for X-ray phase-contrast imaging with a hospital-grade X-ray tube in...

We investigate the occurrence of self-images, or Talbot images, in a spatially multimode field that propagates along an optical fiber whose core has an annular-shaped cross section. By use of full-vectorial modal analysis, we study the effect of the transverse fiber dimensions on the self-imaging properties. According to our analysis, good self-images can be expected when the fiber core is thin...

A matter wave ghost imaging mechanism is proposed and demonstrated theoretically. This mechanism is based on the Talbot-Lau effect. Periodic gratings of matter wave density, which appear as a result of interference of atoms diffracted by pulses of an optical standing wave, are utilized to produce the reference wave and the signal wave simultaneously for the ghost imaging. An advantage of this m...

Charles H. Talbot, PhD, BD, BCL, died at his home in London on 13 September 1993 of a stroke at the age of eighty-seven. He was best known to medical history as a leading expert on medieval England. He also made notable contributions to the fields of Cistercian studies and the history of the Anglo-Saxon church. Born in Portsmouth in 1906, Charles Talbot received his education at Mundella School...

Recent findings show that the classical Riemann's non-differentiable function has a physical and geometric nature as irregular trajectory of polygonal vortex filament driven by binormal flow. In this article, we give an upper estimate its Hausdorff dimension. We also adapt result to multifractal setting. To prove these results, recalculate asymptotic behavior around rationals from novel perspec...
