TL;DR
This paper introduces a method using spinorial formalism to translate electromagnetic waves with orbital angular momentum into their gravitational counterparts, expanding understanding of gravitational wave structures.
Contribution
It presents a novel approach to generate gravitational waves with orbital angular momentum from electromagnetic wave analogs using linearized gravity.
Findings
Gravitational waves can carry orbital angular momentum similar to light beams.
The spinorial formalism effectively maps electromagnetic wave properties to gravitational waves.
Potential applications in gravitational wave detection and quantum information.
Abstract
Spinorial formalism is used to map every electromagnetic wave into the gravitational wave (within the linearized gravity). In this way we can obtain the gravitational counterparts of Bessel, Laguerre-Gauss, and other light beams carrying orbital angular momentum.
