Effects of Critical Collapse on Primordial Black-Hole Mass Spectra
Florian Kuhnel, Cornelius Rampf, Marit Sandstad
Certain inflationary models as well as realisations of phase transitions in the early Universe predict the formation of primordial black holes. For most mass ranges, the fraction o…
Effectively nonlocal metric-affine gravity
Alexey Golovnev, Tomi Koivisto, Marit Sandstad
In metric-affine theories of gravity such as the C-theories, the spacetime connection is associated to a metric that is nontrivially related to the physical metric. In this article…
Baryon number conservation in Bose-Einstein condensate black holes
Florian Kühnel, Marit Sandstad
Primordial black holes are studied in the Bose-Einstein condensate description of space-time. The question of baryon-number conservation is investigated with emphasis on possible f…
Corpuscular Consideration of Eternal Inflation
Florian Kuhnel, Marit Sandstad
We review the paradigm of eternal inflation in the light of the recently proposed corpuscular picture of space-time. Comparing the strength of the average fluctuation of the field…
