High energy physics theory seminar: Sizheng Ma (Perimeter Institute)

Title: Cauchy-characteristic matching, Abstract: Cauchy-characteristic matching is a novel numerical-relativity technique that enables the evolution of Einstein’s equations on an effectively infinite computational domain. In this talk, I will present our recent successful applications of this method to binary black hole mergers, and demonstrate its transformative potential for modeling tail and memory effects in eccentric binaries.

AMO seminar: Alan Jamison (Waterloo)

Title: Ultracold Molecules: From Quantum Chemistry to Quantum Computing, Abstract: At ultracold temperatures, we can prepare reactants in well-defined quantum states. Doing so allows us to study the quantum dynamics of individual reaction channels. I will present our work on ultracold chemistry using triplet NaLi molecules. First, we discovered strongly spin dependent chemistry. For certain […]

Department-wide colloquium, Bearden lecture: Liang Wu (Penn)

Title: New Photo-galvanic effects, Abstract: The conventional device to convert light to electrical current uses two different kinds of doped silicon merged together known as pn junction or heterostructures. The current only flows one way in the pn junction due to a built-in electric field. Fabricating such heterostructures requires sophisticated thin film deposition methods. In […]

Title: Where is tree-level string theory? Abstract: Tree-level string theory extends Einstein gravity by an infinite set of massive higher spin particles. From a purely spacetime perspective (if we didn’t know about the worldsheet picture) the consistency of string amplitudes would appear truly miraculous. This prompts the question: is string theory the unique framework for a higher […]

Condensed matter & biological physics seminar: Divine Kumah (Duke)

Host: Jazzmin Victorin Title: “Emergent metallicity and superconductivity at oxide heterointerfaces” Abstract: Perovskite-structured complex oxides exhibit a diverse array of physical properties, including magnetism, superconductivity, ferroelectricity, and metal-insulator transitions. The electronic, structural, and magnetic interactions at interfaces formed between crystalline, atomically-thin layers of these materials lead to the emergence of novel phases. Advances in the […]

Title: Polymer models for the prediction of 3D structure and transcription in human chromatin, Talk abstract: Transcription is a fundamental cellular process, and the first step of gene expression. In human cells, it depends on the binding to chromatin of various proteins, including RNA polymerases and numerous transcription factors (TFs). Observations indicate that these proteins […]
