High Energy Seminar: "T-Duality and Scattering of Stringy States"
Jnan Maharana (IOP Bhubaneswar)
I shall review some of the salient features of
T-duality from the
perspective of the worldsheet description of a closed compactified bosonic
string. The vertex operators associated with the moduli G and B…
Condensed Matter seminar: "Tracking Photoinitiated Dynamics of Photosystem I and Model Systems Through Ultrafast Spectroscopy"
Jessica Anna, University of Pennsylvania
Photosystem I (PSI) is a natural light harvesting complex that catalyzes oxygenic photosynthesis through a trans-membrane electron transfer. It is also known to be one of nature’s most efficient energy converters –…
Astro Seminar: "The Remarkable Proto-planetary Disks HL Tau: Watching the Formation of Planets"
Crystal Brogan (NRAO)
Spatially resolved ALMA studies of protoplanetary disks at millimeter wavelengths are revolutionizing the study of these precursors to solar systems. In this talk I will present results from observations of the…
Experimental Particle Physics: "Di-Higgs at the LHC: Current Status and Future Prospects"
John Alison (University of Chicago)
I will discuss motivations for searching for di-Higgs production at the LHC. Recent results and projected sensitivities will be presented with particular emphasis on the dominant hh->4b channel.
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…
