Gravitational Waves from Preheating in M-flation
Amjad Ashoorioon, Brandon Fung, Robert B. Mann +2
Matrix inflation, or M-flation, is a string theory motivated inflationary model with three scalar field matrices and gauge fields in the adjoint representation of the $\mathbf{U}(N…
Hairy planar black holes in higher dimensions
Andres Acena, Andres Anabalon, Dumitru Astefanesei +1
We construct exact hairy planar black holes in D-dimensional AdS gravity. These solutions are regular except at the singularity and have stress-energy that satisfies the null energ…
Out of the White Hole: A Holographic Origin for the Big Bang
Razieh Pourhasan, Niayesh Afshordi, Robert B. Mann
While most of the singularities of General Relativity are expected to be safely hidden behind event horizons by the cosmic censorship conjecture, we happen to live in the causal fu…
Numerical Boson Stars with a Single Killing Vector II: the D=3 Case
Sean Stotyn, Melanie Chanona, Robert B. Mann
We complete the analysis of part I in this series (Ref. \cite{Stotyn:2013yka}) by numerically constructing boson stars in 2+1 dimensional Einstein gravity with negative cosmologica…
Kerr-AdS analogue of triple point and solid/liquid/gas phase transition
Natacha Altamirano, David Kubiznak, Robert B. Mann +1
We study the thermodynamic behavior of multi-spinning d=6 Kerr-anti de Sitter black holes in the canonical ensemble of fixed angular momenta J1 and J2. We find, dependent on the ra…
Exact asymptotically flat charged hairy black holes with a dilaton potential
Andres Anabalon, Dumitru Astefanesei, Robert Mann
We find broad classes of exact 4-dimensional asymptotically flat black hole solutions in Einstein-Maxwell theories with a non-minimally coupled dilaton and its non-trivial potentia…
