Periodic Cosmic String Formation and Dynamics
Michael A. Fedderke, Junwu Huang, Nils Siemonsen
We study string formation and dynamics in a scalar field theory with a global symmetry. If a scalar field is initially displaced from the minimum of a wine-bottle poten…

A Precision Gyroscope from the Helicity of Light
Michael A. Fedderke, Roni Harnik, David E. Kaplan +4
We describe a gyroscope that measures rotation based on the effects of the rotation on the polarization of light. Rotation induces a differential phase shift in the propagation of…

Picolensing as a Probe of Primordial Black Hole Dark Matter
Michael A. Fedderke, Sergey Sibiryakov
The gravitational-lensing parallax of gamma-ray bursts (GRBs) is an intriguing probe of primordial black hole (PBH) dark matter in the asteroid-mass window, $2\times 10^{-16}M_{\od…
