Transport along Null Curves
Joseph Samuel, Rajaram Nityananda
Fermi Transport is useful for describing the behaviour of spins or gyroscopes following non-geodesic, timelike world lines. However, Fermi Transport breaks down for null world line…

Is Barbero's Hamiltonian formulation a Gauge Theory of Lorentzian Gravity?
Joseph Samuel
This letter is a critique of Barbero's constrained Hamiltonian formulation of General Relativity on which current work in Loop Quantum Gravity is based. While we do not dispute the…

Canonical Gravity, Diffeomorphisms and Objective Histories
Joseph Samuel
This paper discusses the implementation of diffeomorphism invariance in purely Hamiltonian formulations of General Relativity. We observe that, if a constrained Hamiltonian formula…
