Ultralight Fermionic Dark Matter
Hooman Davoudiasl, Peter B. Denton, David A. McGady
Conventional lore from Tremaine and Gunn excludes fermionic dark matter lighter than a few hundred eV, based on the Pauli exclusion principle. We highlight a simple way of evading…
The Schwinger mechanism revisited
Thomas D. Cohen, David A. McGady
The vacuum persistence probability, , for a system of charged fermions in a fixed, external, and spatially homogeneous electric field, was derived long ago by Schwinger…
The chiral condensate in a constant electromagnetic field
Thomas D. Cohen, David A. McGady, Elizabeth S. Werbos
We study the shift of the chiral condensate in a constant electromagnetic field in the context of chiral perturbation theory. Using the Schwinger proper-time formalism, we derive a…
