Lecture

Axion Strings: CMB Millikan Experiment

Description

This lecture explores the properties of axion strings in the context of cosmic microwave background (CMB) experiments. Topics include the formation of string networks, axion mass constraints, axiverse models, photon interactions in axion string backgrounds, and the quantization of electric charge. The lecture also covers CMB observables, cosmic birefringence, and methods for studying polarization rotation through semi-analytical approaches and numerical simulations.
