Primordial Black Holes as Dark Matter
Bernard Carr, Florian Kuhnel, Marit Sandstad
The possibility that the dark matter comprises primordial black holes (PBHs) is considered, with particular emphasis on the currently allowed mass windows at - $10^{17}\,…
Astrophysical Bose-Einstein Condensates and Superradiance
Florian Kuhnel, Cornelius Rampf
We investigate gravitational analogue models to describe slowly rotating objects (e.g., dark-matter halos, or boson stars) in terms of Bose-Einstein condensates, trapped in their o…
Decay of Graviton Condensates and their Generalizations in Arbitrary Dimensions
Florian Kuhnel, Bo Sundborg
Classicalons are self-bound classical field configurations, which include black holes in General Relativity. In quantum theory, they are described by condensates of many soft quant…
Large-Scale Suppression from Stochastic Inflation
Florian Kuhnel, Dominik J. Schwarz
We show non-perturbatively that the power spectrum of a self-interacting scalar field in de Sitter space-time is strongly suppressed on large scales. The cut-off scale depends on t…
