Thermalization, Fragmentation and Tidal Disruption: The Complex Galactic Dynamics of Dark Matter Superfluidity
Lasha Berezhiani, Giordano Cintia, Justin Khoury
The idea of self-interacting bosonic dark matter capable of exhibiting superfluidity is revisited. We show that the most interesting parameter space of the theory corresponds to fu…
Implications of the Weak Gravity Conjecture for Tidal Love Numbers of Black Holes
Valerio De Luca, Justin Khoury, Sam S. C. Wong
The Weak Gravity Conjecture indicates that extremal black holes in the low energy effective field theory should be able to decay. This criterion gives rise to non-trivial constrain…
Stability of Hairy Black Holes in Shift-Symmetric Scalar-Tensor Theories via the Effective Field Theory Approach
Justin Khoury, Toshifumi Noumi, Mark Trodden +1
Shift-symmetric Horndeski theories admit an interesting class of Schwarzschild-de Sitter black hole solutions exhibiting time-dependent scalar hair. The properties of these solutio…
Bayesian Reasoning in Eternal Inflation: A Solution to the Measure Problem
Justin Khoury, Sam S. C. Wong
Probabilities in eternal inflation are traditionally defined as limiting frequency distributions, but a unique and unambiguous probability measure remains elusive. In this paper, w…
Finite Temperature Description of an Interacting Bose Gas
Anushrut Sharma, Guram Kartvelishvili, Justin Khoury
We derive the equation of state of a Bose gas with contact interactions using relativistic quantum field theory. The calculation accounts for both thermal and quantum corrections u…
