Aharonov-Bohm Radiation

Understand

A solenoid oscillating in vacuum will pair produce charged particles due to the Aharonov-Bohm (AB) interaction.

• We calculate the radiation pattern and power emitted for charged scalar particles.
• We extend the solenoid analysis to cosmic strings, and find enhanced radiation from cusps and kinks on loops.
• We argue by analogy with the electromagnetic AB interaction that cosmic strings should emit photons due to the gravitational AB interaction of fields in the conical spacetime of a cosmic string.
