Rewinding the Void: How One Solution of Einstein's Field Equations Describes Both the Birth of a Universe and the End of Time
Charles W. Robson, Marco Ornigotti
The type D Kasner vacuum solution of general relativity is reviewed, highlighting the little-known, intriguing property that it can describe both an anisotropic cosmology and the s…
Take the A-Metric: Interpretations of Some Known Solutions of Einstein's Vacuum Field Equations
Charles W. Robson, Marco Ornigotti
In this work, we present a new interpretation of the only static vacuum solution of Einstein's field equations with planar symmetry, the Taub solution. This solution is a member of…
High-accuracy longitudinal position measurement using self-accelerating light
Shashi Prabhakar, Stephen Plachta, Marco Ornigotti +1
Radially self-accelerating light exhibits an intensity pattern that describes a spiraling trajectory around the optical axis as the beam propagates. In this article, we show in sim…
Localized waves carrying orbital angular momentum in optical fibers
Paula Nuño Ruano, Charles W. Robson, Marco Ornigotti
We consider the effect of orbital angular momentum (OAM) on localized waves in optical fibers using theory and numerical simulations, focusing on splash pulses and focus wave modes…
Interacting ring-Airy beams in nonlinear media
Charles W. Robson, Marco Ornigotti
The interactions between copropagating ring-Airy beams in a (2+1)-dimensional Kerr medium are numerically investigated for the first time. It is shown that two overlapping ring-Air…
Transient perturbative nonlinear responses of plasmonic materials
Mikko J. Huttunen, Jussi Kelavuori, Marco Ornigotti
Recent investigations on optical nonlinearities of plasmonic materials suggest their responses may be even beyond the usual perturbative description. To better understand these sur…
