HET/HEE Seminar: Professor Vishnu Jejjala, December 12 *Special Time!*

[Francis, Brian]

Hello again,

This is a reminder that today! we will be hearing from Professor Vishnu Jejjala in the High Energy Physics seminar. This is a special date, being on a Tuesday. Please come to the 4th floor at 3:30 to hear about his work with Calabi-Yau geometries.

Tuesday, December 12, 2017
3:30 PM
Room 4138, Physics Research Building
*Note special time*

Speaker: Professor Vishnu Jejjala
Title: Aspects of Calabi-Yau Geometries
We explore the distribution of topological numbers in Calabi-Yau manifolds using the Kreuzer-Skarke dataset of hypersurfaces in toric varieties as a testing ground. While the Hodge numbers are well-known to exhibit mirror symmetry, patterns in frequencies exhibit striking new patterns. In analyzing the Kreuzer-Skarke database, we present a new algorithm to isolate Swiss cheese solutions, many of which have multiple large cycles. Such Swiss cheese geometries facilitate moduli stabilization in string compactifications and provide flat directions for cosmological inflation. We discuss ongoing and future work with these datasets.
