Spinor-helicity and the algebraic classification of higher-dimensional spacetimes
Ricardo Monteiro, Isobel Nicholson, Donal O'Connell
The spinor-helicity formalism is an essential technique of the amplitudes community. We draw on this method to construct a scheme for classifying higher-dimensional spacetimes in t…
Semiclassical instabilities of Kerr-AdS black holes
Ricardo Monteiro, Malcolm J. Perry, Jorge E. Santos
We study the thermodynamic stability of the Kerr-AdS black hole from the perturbative corrections to the gravitational partition function. The line of critical stability is identif…
Thermodynamic instability of rotating black holes
Ricardo Monteiro, Malcolm J. Perry, Jorge E. Santos
We show that the quasi-Euclidean sections of various rotating black holes in different dimensions possess at least one non-conformal negative mode when thermodynamic instabilities…
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…
