The Hydrogen Mixing Portal, Its Origins, and Its Cosmological Effects
Lucas Johns, Seth Koren
Hydrogen oscillation into a dark-sector state has recently been proposed as a novel mechanism through which hydrogen can be cooled during the dark ages -- without direct coupl…

Hydrogen Mixing as a Novel Mechanism for Colder Baryons in 21 cm Cosmology
Lucas Johns, Seth Koren
The anomalous 21 cm absorption feature reported by EDGES has galvanized the study of scenarios in which dark matter (DM) siphons off thermal energy from the Standard Model (SM) gas…

Fast oscillations, collisionless relaxation, and spurious evolution of supernova neutrino flavor
Lucas Johns, Hiroki Nagakura, George M. Fuller +1
Mounting evidence indicates that neutrinos likely undergo fast flavor conversion (FFC) in at least some core-collapse supernovae. Outcomes of FFC, however, remain highly uncertain.…
