Fracton infrared triangle
Alfredo Pérez, Stefan Prohazka, Ali Seraj
In theories with conserved dipole moment, isolated charged particles (fractons) are immobile, but dipoles can move. We couple these dipoles to the fracton gauge theory and analyze…
Orientation Memory of Magnetic Dipoles
Blagoje Oblak, Ali Seraj
We study the precession caused by electromagnetic radiation on a magnetic dipole located far from the source. As we show, this entails a net rotation of the dipole in the plane ort…
Memory effects from holonomies
Ali Seraj, Turmoli Neogi
We provide a uniform treatment of electromagnetic and gravitational memory effects, based on the gravito-electromagnetic formulation of GR and a generalization of the geodesic devi…
Metric reconstruction from celestial multipoles
Geoffrey Compère, Roberto Oliveri, Ali Seraj
The most general vacuum solution to Einstein's field equations with no incoming radiation can be constructed perturbatively from two infinite sets of canonical multipole moments, w…
Gyroscopic Gravitational Memory
Ali Seraj, Blagoje Oblak
We study the motion of a gyroscope located far away from an isolated gravitational source in an asymptotically flat spacetime. As seen from a local frame tied to distant stars, the…
Gravitational breathing memory and dual symmetries
Ali Seraj
Brans-Dicke theory contains an additional propagating mode which causes homogeneous expansion and contraction of test bodies in transverse directions. This "breathing" mode is asso…
