The Kinematic Algebra From the Self-Dual Sector
Ricardo Monteiro, Donal O'Connell
We identify a diffeomorphism Lie algebra in the self-dual sector of Yang-Mills theory, and show that it determines the kinematic numerators of tree-level MHV amplitudes in the full…

Negative modes and the thermodynamics of Reissner-Nordström black holes
Ricardo Monteiro, Jorge E. Santos
We analyse the problem of negative modes of the Euclidean section of the Reissner-Nordström black hole in four dimensions. We find analytically that a negative mode disappears when…

Varying Electromagnetic Coupling and Primordial Magnetic Fields
O. Bertolami, R. Monteiro
We study the effect of variations of the electromagnetic coupling on the process of generation of primordial magnetic fields. We find that only through a significant growth of the…
