The "swampland conjectures" have been recently suggested as a set of criteria to assess if effective field theories (EFTs) are consistent with a quantum gravity embedding. Such criteria, which restrict the behavior of scalar fields in the theory, have strong implications for cosmology in the early universe. As we demonstrate, they will also have direct consequences for formation of primordial black holes (PBHs) and dark matter (DM).

  1. Fundamental Forces and Scalar Field Dynamics in the Early Universe

    hep-th 2019-08 conditional novelty 7.0 of 10

    The paper shows that generalized scalar weak gravity conjectures imply the parameter conditions for early-universe scalar condensates to fragment into solitonic lumps, which could form dark matter or primordial black holes.

    PBH-triggered SN Ia models across metallicities match some observed light curves and remnants, constrain the explosion channel fraction via chemical evolution modeling, and indicate PBHs as a potentially major early-u...
