High Energy Theory Seminar: Resolution Invariance of Intersection Pairings on Calabi-Yau Manifolds

Patrick Jefferson (Johns Hopkins University)
- David Rittenhouse Laboratory, 3C6

Studies of string theory compactifications suggest that certain “vertical” homological intersection pairings of Calabi-Yau manifolds are invariant under a large set of birational transformations. In this talk, I will…



Rittenhouse Lecture: An imperfect view of the Universe

Alan Heavens (Imperial College London)
- David Rittenhouse Laboratory, A4

Our most expensive telescopes make exquisite images of the distant Universe, but however good the telescope, the images are flawed.  The light has been on a long journey, navigating through the rich array…

High Energy Theory Seminar: "The Callan Rubakov Effect"

T. Daniel Brennan (University of California San Diego)
- David Rittenhouse Laboratory, 3C6

The Callan Rubakov Effect describes the interaction between (massless) fermions and a smooth monopole in 4d gauge theory. In this scenario, the fermions can probe the UV physics inside the monopole core which leads…



Condensed Matter Seminar: Roller-Coaster in a Flatland: Magnetoresistivity in Eu-intercalated Graphite

Dr. Sasha Chernyshev (University of California, Irvine)
- David Rittenhouse Laboratory, A4

Novel phenomena in magnetically-intercalated graphite has been a subject of much research in the 1980s, with the most enigmatic findings of that era being a dramatic, roller-coaster-like behavior of the…
