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…
Globally defined Carroll symmetry of gravitational waves
Mahmut Elbistan, Peng-Ming Zhang, Peter Horvathy
The local Carroll symmetry of a gravitational wave found in Baldwin-Jeffery-Rosen coordinates is extended to a globally defined one by switching to Brinkmann coordinates. Two indep…
Schrödinger symmetry: a historical review
Christian Duval, Malte Henkel, Peter Horvathy +2
This paper reviews the history of the conformal extension of Galilean symmetry, now called Schrödinger symmetry. In the physics literature, its discovery is commonly attributed to…
Kerner equation for motion in a non-Abelian gauge field
Peter A Horvathy, Peng-Ming Zhang
The equations of motion of an isospin-carrying particle in a Yang-Mills and gravitational field were first proposed in 1968 by Kerner, who considered geodesics in a Kaluza-Klein-ty…
Isospin precession in non-Abelian Aharonov-Bohm scattering
Peng-Ming Zhang, Peter Horvathy
The concept of pseudoclassical isospin is illustrated by the non-Abelian Aharonov-Bohm effect proposed by Wu and Yang in 1975. The spatial motion is free however the isospin preces…
