Math-Bio seminar: "Vector diffusion maps and the graph connection Laplacian"
Amit Singer, Princeton University
Vector diffusion maps (VDM) is a mathematical framework for organizing and analyzing high-dimensional datasets that generalizes diffusion maps and other nonlinear dimensionality reduction methods, such as LLE,…
High Energy Theory: Relative Entropy of Excited States in Conformal Field Theories
Gabor Sarosi (VUB)
We study the relative entropy between the reduced density matrices obtained from globally excited states in conformal field theories of arbitrary dimensions. We find a general formula in the small subsystem size…

Experimental Particle Physics: "Improving T2K Oscillation Results with a Maximum Likelihood Event Reconstruction"
Andrew Missert (University of Colorado, Boulder)
The Tokai-to-Kamioka (T2K) experiment is an accelerator-based long-baseline neutrino oscillation experiment that uses a unique off-axis neutrino beam to precisely measure the parameters that govern neutrino flavor…
Condensed Matter seminar: "Life as an emergent phenomenon: how local interactions lead to biological function at the global scale"
Timon Idema, Delft University of Technology
Life exists by virtue of collective phenomena. From the cells in a tissue down to the proteins inside a cell, cooperation is key for function and thus survival. We study the physics of these many-component systems,…
Astro Seminar: "Living la vida loca: How to Assemble a Massive Dead Galaxy by z=1.0-1.5"
Helena Dominguez-Sanchez (Universidad Complutense de Madrid)
Three billion years after the big bang (at redshift z = 2), half of the most massive galaxies were already old, quiescent systems with little to no residual star formation. How were the lives of these galaxies so…
Math-Bio seminar: "Quantitative methods for comparing T cell repertoires"
Philip Johnson, Univesity of Maryland
The vertebrate T cell adaptive immune response has the challenging task of recognizing all possible pathogens while not attacking "self." Evolution's solution to this challenge has been to generate a repertoire of…
High Energy Seminar: "Recent Developments in 3-D Dualities"
Jeff Murugan (University of Cape Town)
This summer has seen a flurry of activity in particle-vortex duality and, more generally, in non-supersymmetric dualities in three spacetime dimensions. Much of this work has been directly related to the properties…
Condensed Matter seminar: "Entanglement dynamics following quantum quenches in Floquet topological insulators and quantum critical systems"
Aditi Mitra, New York University
Recent years have shown that entanglement is a useful way to characterize quantum many body systems, however concrete results only exist in one spatial dimension. In this talk I will present results for the dynamics…
Astro Seminar: "Understanding large-scale structure from the CMB"
Emmanuel Schaan (Princeton)
In this seminar, I will present two ways in which the cosmic microwave background (CMB) sheds light on critical uncertain physics and systematics of the large-scale structure.
Shear calibration with…
