Gravitational Memory Effect in the Massless Vector Field
Pouneh Safarzadeh Ilkhchi, Amin Rezaei Akbarieh, Shaoqi Hou
We analyze the infrared structure and memory effects of a massless vector tensor theory with non minimal curvature coupling in asymptotically flat spacetimes. Using Bondi Sachs exp…

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…
