The String Axiverse: Axion-Photon Couplings and Universality

Explore a 42-minute conference talk on "The String Axiverse: Axion-photon couplings and universality" presented by Naomi Gendler from Harvard University. Delve into cutting-edge research in string theory and its implications for spacetime and quantum information. Recorded as part of the Spacetime and String Theory conference at the Kavli Institute for Theoretical Physics (KITP), this presentation bridges the gap between infrared and ultraviolet perspectives in string theory. Gain insights into non-perturbative string theory, stringy constraints on effective field theory, and the connections between gravitational path integrals, higher topologies, and entanglement. Discover how this talk contributes to a new synthesis in the field, building on recent progress in quantum information, string compactification, and holographic dualities beyond anti-de Sitter space.
