Memory Effect for deformed gravitational waves

P. -M. Zhang, M. Elbistan, P. A. Horvathy

Deformations of sandwich gravitational waves are considered. Squeezing a wave with pure displacement (DM) parameters to an impulsive wave, the DM property is lost, leaving us with…

Approximate Models for Gravitational Memory

Q-L Zhao, P. -M. Zhang, M. Elbistan +1

The large-distance approximation of a sandwich gravitational wave by a continuous but not necessarily smooth profile provides us with an approximate analytic description of particl…

Flyby-induced displacement: analytic solution

P. -M. Zhang, Z. K. Silagadze, P. A. Horvathy

The motion of particles hit by a burst of gravitational waves generated by flyby admits, for the derivative-of-the-Gaussian profile, only a numerical description. The profile can h…

Ion Traps and the Memory Effect for Periodic Gravitational Waves

P. -M. Zhang, M. Cariglia, C. Duval +3

The Eisenhart lift of a Paul Trap used to store ions in molecular physics is a linearly polarized periodic gravitational wave. A modified version of Dehmelt's Penning Trap is in tu…

Displacement memory for flyby

P. -M. Zhang, Q. -L. Zhao, J. Balog +1

Zel'dovich and Polnarev, in their seminal paper [1] suggested that a gravitational wave generated by flyby would merely displace the particles. We confirm their prediction numerica…

Memory Effect and Carroll Symmetry: 50 years later

M. Elbistan, P. -M. Zhang, P. A. Horvathy

Particles at rest before the arrival of a burst of gravitational wave move, after the wave has passed, with constant velocity along diverging geodesics. As recognized by Souriau 50…
