Abstract: I will present recent work that has succeeded in embedding the mechanism of Unwinding Inflation in string theory. I will review Unwinding Inflation and the process of brane-flux annihilation, in which D-branes lower flux numbers and therefore the 4D vacuum energy. A dynamical brane mediates the brane-flux annihilation as it moves across a compact internal cycle. This mechanism has recently been extended such that many units of flux can be discharged in a “flux cascade.” The flux cascade can be used to substantially reduce vacuum energy and give rise to 60 efolds of inflation.
