AbstractIn this talk, we identify a Zs discrete gravitational theta angle in the non-supersymmetricSO(16) x SO(16) heterotic string, which is detected by a 10D spacetime manifold that is anSp(2) group manifold. In the first part, we explain the string theory computation that identifies thisZ, theta angle, involving non-perturbative anomaly on the instantonic NS5 branes. in the secondpart, we mo...
AbstractTTbar is a solvable irrelevant deformation that leads to interesting properties such as nonlocality. When applied to a CFT, the effects of TTbar can be studied via cutoff and glue-on holography. In this talk, we will first introduce the glue-on geometry, which reveals many interesting features of TTbar deformed CFTs that were previously inaccessible through cutoff holography. We then in...
