High Energy Theory Seminar: Resolution Invariance of Intersection Pairings on Calabi-Yau Manifolds
Patrick Jefferson (Johns Hopkins University)
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)
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…

High Energy Theory Seminar: "The Callan Rubakov Effect"
T. Daniel Brennan (University of California San Diego)
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…
Condensed Matter Seminar: Roller-Coaster in a Flatland: Magnetoresistivity in Eu-intercalated Graphite
Dr. Sasha Chernyshev (University of California, Irvine)
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…
