The flux of angular momentum in electromagnetism cannot be expressed entirely in terms of the field's radiative degrees of freedom. Its expression also involves Coulombic pieces of the field, in the form of a charge aspect q(theta,phi), a function of polar angles whose integral gives the total charge of the system. Guided by the strong analogy between radiative processes in electromagnetism...
Thanks to recent gravitational wave observations, we have evidence for the validity of Einstein’s theory in the strong field region, including near black hole event horizons. The existence of black holes gives rise to theoretical issues, such as the necessary existence of singularities and the related information loss conundrum, that will hopefully be resolved by quantum mechanics. In the...
The oral presentation will consist primarily of a recently published article in International Journal of Modern Physics D entitled "A connection between linearized Gauss–Bonnet gravity and classical electrodynamics", authored by MR Baker and S Kuzmin. In this article, a connection between a well known gravitational model and classical electrodynamics is derived. Given the excitement among...
We show how the zeroth, first, and second laws of black hole thermodynamics emerge from a generic semiclassical theory of gravity. The zeroth law is a kinematic property of bifurcate Killing horizons. It depends neither on details of the semiclassical coupling nor on the dynamics of gravity. The first law is established for stationary spacetimes for which a Hamiltonian can be defined. The...
