Horizon flux-balance laws in the multiscale perturbation
Ali Seraj
Black-hole event horizons obey a set of evolution equations governing their intrinsic and extrinsic geometry. We study these equations in a \textit{two-timescale} perturbative expa…
Memory of Robinson-Trautman waves
Glenn Barnich, Ali Seraj
The memory effect for Robinson-Trautman waves is explicitly worked out. In a first step, we construct the combined frame rotation and coordinate transformation in which Robinson-Tr…
Gravitational Holonomy in Sagnac Interferometry
Reza Javadinezhad, Ali Seraj
We analyze the influence of gravitational waves on a Sagnac interferometer formed by the interference of two counter-propagating beams traversing a closed spatial loop. In addition…
Gravitational memory effects in Tachyon gravity
Pouneh Safarzadeh Ilkhchi, Amin Rezaei Akbarieh, Ali Seraj
In this paper, we explore how a massless Tachyon field, when non-minimally coupled to gravity, affects gravitational memory, soft theorems, and symmetries near null infinity. We se…
Gyroscopic Gravitational Memory from quasi-circular binary systems
Guillaume Faye, Ali Seraj
Gravitational waves cause freely falling spinning objects to precess, resulting in a net orientation change called gyroscopic memory. In this paper, we will consider isolated gravi…
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…
