Conifunneling : An Extreme Path on the Landscape

This seminar will centre on joint work by the speaker, Brian Greene, and others, on some interesting novel behaviours in vacuum transitions in the Type IIB string landscape. It will be accessible to the whole T-HEP group (and interested CITAzens), not just string theorists.

Abstract:

We studied vacuum transition on the landscape of type IIB string theory, with the family of simplest possible Calabi-Yau 3-folds. We found that during the trantision, the Calabi-Yau tends to be extremely deformed. In our special case it develops a strongly warped connifold as described by Klebanov and Strassler. We discussed how this extreme behavior will help us better understand the structure of the landscape.
