Particle trajectories in light pulse spacetime

TL;DR

This paper derives particle trajectories in light pulse spacetime, showing observable perturbations in gamma ray bursts and larger deviations for moving particles compared to stationary ones.

Contribution

It extends previous work by deriving geodesics with zero angular velocity and analyzing particle motion deviations in light pulse spacetime.

Findings

Perturbations in particle trajectories may be observed in gamma ray bursts.

Deviations in moving particles are significantly larger than for initially at rest.

Provides a detailed set of geodesics in cylindrically shaped light pulse spacetime.

Abstract

In our previous work (Phys. Rev. Research 7, 033079), we derived the metric tensor for cylindrically shaped pulses with uniform energy density. Building upon that framework, we derive the complete set of geodesics with zero angular velocity. We show that perturbations in particle trajectories may be observed in gamma ray bursts. Also, deviations in the motion of moving particles are significantly larger than those previously found for particles that are initially at rest.
