Trapping and guiding bodies by gravitational waves endowed with angular momentum

It has been established theoretically and experimentally confirmed that electromagnetic waves endowed with angular momentum (for example, Bessel beams) can trap charged particles in the vicinity of the beam center. It can be shown that trapping of bodies by waves can be extended from electromagnetism to gravity. In contrast to the electromagnetic case, the trapping in the gravitational case is universal; it does not depend on the mass of the body. The presentation of the trapping mechanism is based on the simplest model of a gravitational wave carrying angular momentum which is the Bessel beam.
