Light from Cosmic Strings
Daniele A. Steer, Tanmay Vachaspati
The time-dependent metric of a cosmic string leads to an effective interaction between the string and photons - the "gravitational Aharonov-Bohm" effect -- and causes cosmic string…
Shape of Cosmic String Loops
Craig J Copi, Tanmay Vachaspati
Complicated cosmic string loops will fragment until they reach simple, non-intersecting ("stable") configurations. Through extensive numerical study we characterize these attractor…
Aharonov-Bohm Radiation of Fermions
Yi-Zen Chu, Harsh Mathur, Tanmay Vachaspati
We analyze Aharonov-Bohm radiation of charged fermions from oscillating solenoids and cosmic strings. We find that the angular pattern of the radiation has features that differ sig…
Spectra of Magnetic Fields Injected during Baryogenesis
Yifung Ng, Tanmay Vachaspati
Helical magnetic fields are injected into the cosmic medium during cosmological baryogenesis and can potentially provide a useful probe of the early universe. We construct a model…
Capacitor Discharge and Vacuum Resistance in Massless QED_2
Yi-Zen Chu, Tanmay Vachaspati
A charged parallel plate capacitor will create particle-antiparticle pairs by the Schwinger process and discharge over time. We consider the full quantum discharge process in 1+1 d…
