Photon localization: a comparative study
Laura M. Ferguson, Ricardo Rojas Castellano, Kayla Oltman +2
We compare different measures for photon localization in terms of two-dimensional Gaussian wave packets. We find that all measures start to coalesce if the wave packet has evolved…

Consistency Conditions and the Derivation of Harmonic Structure in Einstein-Maxwell-dilaton Theory
Bardia H. Fahim, Joshua G. Fenwick
Many exact solutions of Einstein-Maxwell and Einstein-Maxwell-dilaton theory share a common structural pattern in which the metric functions are built from harmonic functions on a…

Antisymmetric tensor portals to dark matter
Alexander J. Magnus, Joshua G. Fenwick, Rainer Dick
Both freeze-in of very weakly coupled dark matter and freeze-out of initially thermalized dark matter from the primordial heat bath provide interesting possibilities for dark matte…
