The Weyl Double Copy for Gravitational Waves
Hadi Godazgar, Mahdi Godazgar, Ricardo Monteiro +2
We establish the status of the Weyl double copy relation for radiative solutions of the vacuum Einstein equations. We show that all type N vacuum solutions, which describe the radi…
ANEC in theory
Teresa Bautista, Lorenzo Casarin, Hadi Godazgar
Motivated by the goal of applying the average null energy condition (ANEC) to renormalisation group flows, we calculate in theory the expectation value of the ANEC operator…
Hamiltonian derivation of dual gravitational charges
Hadi Godazgar, Mahdi Godazgar, Malcolm J. Perry
We provide a Hamiltonian derivation of recently discovered dual BMS charges. In order to do so, we work in the first order formalism and add to the usual Palatini action, the Holst…
Asymptotic gravitational charges
Hadi Godazgar, Mahdi Godazgar, Malcolm J. Perry
We present a method for finding, in principle, all asymptotic gravitational charges. The basic idea is that one must consider all possible contributions to the action that do not a…
