SUMMARY:Workshop / Seminar:From entropic propagation of chaos to concentration bounds for stochastic particle systems
DESCRIPTION:We shall discuss about weakly interacting stochastic particle systems with possibly singular pairwise interactions. In this setting\, we observe a connection between entropic propagation of chaos (proved by Jabin and Wang\, 2018) and exponential concentration bounds for the empirical measure of the system. In particular\, we will show how to establish a variational upper bound for the probability of a certain rare event\, and then use this upper bound to show that ''controlled\" entropic propagation of chaos implies an exponential concentration bound for the empirical measure.

SUMMARY:Workshop / Seminar:GLNT: Mazur's Program B and the geometry of rational points
DESCRIPTION:I'll describe recent progress on Mazur's Program B over Q\, which aims to classify all rational points on all modular curves. Conditional on an effective version of Serre's uniformity conjecture due to Zywina\, we give such a classification. Using our parameterization we try to answer the following question inspired by Ogg: to what extent do rational points on modular curves come from geometry? This is joint work with Maarten Derickx\, Sachi Hashimoto\, and Filip Najman.

SUMMARY:Workshop / Seminar:Gomberg Lecture with Martin Zanni \"Are exciton dynamics in thin films representative of actual solar cells?  Addressing the question using artifact-free ultrafast 2D photocurrent spectroscopy\"
DESCRIPTION:The performance of many photoactive devices is impacted by the dynamics of excitons within the photoactive layer. Typically\, these dynamics are deduced by independently conducted transient absorption measurements on films outside of the device with the assumption that the photophysics in free standing films inform the photophysics of the film inside the device. But there are interfaces in devices that are not present in films and the morphology and atomic packing might be impact by device construction. Moreover\, photoabsorption experiments measure all excitons whereas the best photovoltaic devices are perhaps 20% efficient\, meaning that only 1 in 5 excitons actually produce electricity. Thus\, the conclusions drawn from free standing films might not be directly relevant to devices. This talk will cover results made possible by new advances in ultrafast 2D photocurrent spectroscopy that enable ultrafast exciton dynamics to be directly compared between films and devices. In photovoltaics made from semiconducting carbon nanotubes\, we find that the conclusions drawn from films versus devices are quite different\, leading us to reinterpret long standing experiments and reevaluate our goals for device architecture.

SUMMARY:Lecture / Discussion:Looking for Women\, Finding Jehanne: Gender and Justice in Late Medieval Dijon
DESCRIPTION:This presentation will share some of the findings from Sara's forthcoming book\, tentatively titled Justice for Jehanne\, Survival Stories from Late Medieval France. Written as a police procedural\, it is also a medieval iteration of the timeless tale of a migrant woman from the countryside who struggled to survive in the big city\, in this case Dijon towards the end of the Middle Ages. At that particular time\, in the second half of the fifteenth century\, in the midst of warfare\, endemic disease\, and political upheaval\, Dijon's municipal authorities investigated all manner of crime and other wrongdoing. Women appeared in these investigations most often as victims or as witnesses\, but also as accused of theft\, violence\, sex crimes\, insults\, and sorcery. Sara's presentation offers an investigation of another kind\, one that asks what we can learn from these legal documents about this one woman’s life\, but also about the interworkings of gender\, religion\, and justice in late medieval society.

SUMMARY:Workshop / Seminar:Student combinatorics seminar: Graph tubings\, and the remarkable (lattice!) posets of their maximal tubings
DESCRIPTION:We will discuss a new result that the poset of maximal tubings of the cycle graph is a congruence uniform semi-distributive lattice. The main tool is an interesting new lattice quotient map.
