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…
Stephen William Hawking: A Biographical Memoir
Bernard J. Carr, George F. R. Ellis, Gary W. Gibbons +5
Stephen Hawking's contributions to the understanding of gravity, black holes and cosmology were truly immense. They began with the singularity theorems in the 1960s followed by his…
