They are known to be common in string theory constructions. It can be useful to think of axions as gauge fields for a (-1)-form generalized global symmetry, namely, instanton number. I will use this viewpoint to discuss how axions interact with magnetic monopoles in QFT (and relatedly, why the axion coupling to photons is quantized), and to propose an explanation of the ubiquity of axions in quantum gravity. , Cosmic Happy Hour (8:00 PM - 9:00 PM) + Abstract: | 13 , Equity & Inclusion Committee (12:30 PM - 2:00 PM) Ned Wingreen, Capillary Attraction Underlies Bacterial Collective Dynamics (4:00 PM - 5:30 PM) + Abstract: | 14 Zare (3:30 PM - 5:30 PM) |
