The First Law of Black Hole Mechanics
A simple proof of a strengthened form of the first law of black hole mechanics is presented. The proof is based directly upon the Hamiltonian formulation of general relativity, and it shows that the the first law variational formula holds for arbitrary nonsingular, asymptotically flat perturbations of a stationary, axisymmetric black hole, not merely for perturbations to other stationary, axisy...
متن کاملFirst Law of Mechanics for Black Hole Binaries with Spins
We use the canonical Hamiltonian formalism to generalize to spinning point particles the first law of mechanics established for binary systems of non-spinning point masses moving on circular orbits [Le Tiec, Blanchet, and Whiting, Phys. Rev. D 85, 064039 (2012)]. We find that the redshift observable of each particle is related in a very simple manner to the canonical Hamiltonian and, more gener...
متن کاملOn the Noether charge form of the first law of black hole mechanics
The first law of black hole mechanics was derived by Wald in a general covariant theory of gravity for stationary variations about a stationary black hole. Although it has many advantages, there are several ambiguous points in the derivation. In this paper we point out them and give a clearer derivation of it. After that, we show that there remains a problem when we consider non-stationary pert...
متن کاملD - Brane Approach to Black Hole Quantum Mechanics
D-brane technology has made it possible to identify and precisely count the degenerate quantum states responsible for the entropy of certain extremal, BPS-saturated black holes. Here we give a Type-II D-brane description of a class of extremal and non-extremal five-dimensional Reissner-Nordström solutions. We identify degenerate D-brane configurations that give rise to the Reissner-Nordström so...
متن کاملThe first law for boosted Kaluza-Klein black holes
We study the thermodynamics of Kaluza-Klein black holes with momentum along the compact dimension, but vanishing angular momentum. These black holes are stationary, but non-rotating. We derive the first law for these spacetimes and find that the parameter conjugate to variations in the length of the compact direction is an effective tension, which generally differs from the ADM tension. For the...
