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.
Physics and Astronomy Colloquium: "Computational Epidemiology at the time of COVID-19"
Alessandro Vespigiani (Northeastern University)

Mathematical Biology seminar: "Opinion Dynamics with Tunable Sensitivity: Consensus, Dissensus, and Cascades"
Naomi Leonard (Princeton University)
I will present a general model of continuous-time opinion dynamics for an arbitrary number of agents that sense or communicate over a network and form real-valued opinions about an arbitrary…
High Energy Theory Seminar: Closed strings and weak gravity condition from higher-spin causality
Sandipan Kundu (Johns Hopkins University)
I will show that metastable higher spin particles, free or interacting, cannot couple to gravity while preserving causality unless there exist higher spin states in the gravitational…
Condensed and Living Matter Seminar: "Tiny Robots"
Mark Miskin (University of Pennsylvania)
After 50 years of Moore’s law, it’s now possible to pack nearly 1 million transistors in the space of a paramecium, enabling tiny systems for sensing, communication, and computation. This radical miniaturization of…
Astronomy Seminar: "In Search Of: Failed Supernovae"
