High Energy Theory Seminar: Nonperturbative structures in the SYK model
Mikhail Khramtsov (University of Pennsylvania)
In this talk I will give an overview of the work regarding aspects of the SYK model beyond the commonly used approximations, in particular the replica-diagonal assumption and the conformal limit. We will…
High Energy Experiment Seminar: Off the Beaten Track: Long-Lived Particles at the LHC
Tova Holmes (University of Tennessee)
The LHC has reached a new era: nearly a decade without any large jumps in energy or luminosity. For those interested in finding Beyond the Standard Model (BSM) physics, a paradigm shift is required. In my…
Condensed and Living Matter Seminar: "Non-Hermitian Symmetry and Topology in Photonics "
Liang Feng (University of Pennsylvania)
Symmetry and topology are fundamental notions existing in all kinds of natural systems, from spiral galaxies and hurricanes to amino acids in molecules and non-trivial topologically protected electronic states in…
Astronomy Seminar: Science with XRISM: Resolving the Nature of the Energetic Cosmos
Koji Mukai (GSFC)
The X-Ray Imaging and Spectroscopy Mission (XRISM), an international JAXA/NASA collaboration including participation from ESA, will be an advanced X-ray observatory capable of carrying out a science…
Mathematical Biology seminar: "Modeling and measuring pattern formation in zebrafish skin"
Alexandria Volkening (Northwestern University)
Wild-type zebrafish (Danio rerio) are characterized by black and yellow stripes, which form on their body and fins due to the self-organization of thousands of pigment cells. Mutant zebrafish and sibling…
High Energy Theory Seminar: \lambda\phi^4
Leonardo Senatore (Stanford University)
We resolve the issue of infrared divergences present in theories of light scalar fields on de Sitter space.
Condensed and Living Matter Seminar: "C^4E – Computational Chemistry of Compounds for Catalysis and Energy"
Aleksandra Vojvodic (University of Pennsylvania)
The race to solve the sustainable energy puzzle is on. First-principles based computational methods, which balance accuracy and computational cost, are at the forefront for solving this puzzle. These computational…
Astronomy Seminar: Multi-messenger cosmology: A new frontier
Suvodip Mukherjee (Amsterdam)
The discovery of astrophysical gravitational waves has opened a new avenue to explore the cosmos using transients. I will discuss a few new frontiers in the field of physical cosmology and…
Mathematical Biology seminar: "Constraints on the dimensionality of neural representations: a mesoscale approach linking learning to complex behavior"
Stefano Recanatesi (University of Washington)
In the domain of computational/theoretical neuroscience a recently revived question is about the complexity of neural data. This question can be tackled by studying the dimensionality of such data: is…
High Energy Theory Seminar: Machine Learning and Algebraic Approaches towards Complete Matter
Martin Bies (University of Pennsylvania)
I will discuss recent progress in constructing global 4d F-theory models with realistic vector-like spectra by use of machine learning and algebraic techniques.
