String Theory and Our Universe by Cumrun Vafa

This is an online seminar series on string field theory (SFT) and related topics (worldsheet theory, string amplitudes, compactifications, homotopy algebras…) on Thursday every 2 weeks. Talks are 1.5 hours long: the recommended format is a general introduction of 30 min for students and non-specialists (especially before technical talks), followed by 1 hour of talk + discussions intertwined. Abstract: String theory landscape of vacua point to new consistency conditions that a quantum gravitational system must satisfy. There are only a small number of quantum field theories that satisfy these conditions, and all the rest belong to the `Swampland', which cannot be consistently coupled to gravity. In this talk, I review some of these conditions and their implications for cosmology and particle physics.
