Condensed Matter Theory Seminar: Benjamin Remez, University of Cambridge, “Collective Phenomena in Excitonic Matter”

Abstract: Bound electron-hole pairs, known as excitons, let us realize a plethora of bosonic correlated phases in the solid state. In recent years, the ability to manipulate excitonic states of matter has advanced significantly thanks to novel materials, most notably transition metal chalcogenides such as Ta2NiSe5, TiSe2, and WS2/MoS2 heterobilayers, providing us new access to this rich phase diagram.

The Kimball Smith Series, Sasha Brown, Marynel Vázquez, Wendall Wallach, "AI Ethics on the Global Stage"

AI Ethics on the Global Stage
Join us on Tuesday, November 30th, 2021 at 4 PM in Watson Center (WTS) A74 for a moderated panel followed by small group discussions about artificial intelligence in the contemporary global climate.
The panel will feature experts Wendall Wallach (Interdisciplinary Center for Bioethics), Sasha Brown (World Fellows Program) and Marynel Vázquez (Interactive Machines Group).
Attendees will learn about how AI works and is applied, key recent innovations, current ethical questions, and AI’s impact on the global economy and politics.

Inference Project Virtual Talk: "Bias in Algorithms"

Artificial algorithms are increasingly being deployed to inform, endorse, and govern various aspects of today’s society. Their reach includes the domains of hiring, lending, medicine, criminal justice, insurance, allocation of public services, social and business interactions, and the dissemination of information and news.

Particle Theory Seminar: Hirosi Ooguri, California Institute of Technology, "Symmetry in QFT and Gravity"

Speaker: Hirosi Ooguri (Caltech)
Title: Symmetry in QFT and Gravity
Abstract: I will review aspects of symmetry in quantum field theory and combine them with the AdS/CFT correspondence to derive constraints on symmetry in quantum gravity. The quantum gravity constraints to be discussed include the no-go theorem on global symmetry, the completeness of gauge charges, and the decomposition of high energy states into gauge group representations.

Dissertation Defense: David Stewart, Yale University, "Jet to Event Activity Correlations in Small System Collisions at STAR"

Heavy ion collisions at the LHC and RHIC produce a quark gluon plasma (QGP), in which quarks and gluons are deconfined into an extended medium. This “fourth phase” of matter is also believed to have been the first material phase of the universe following the Big Bang. In experiment, high energy partons scatter at short time scales and may subsequently lose energy, or are “quenched”, via interactions with the QGP.

NPA Seminar, Jay Hyun Jo, Yale University, “First search for an excess of electron neutrinos in MicroBooNE”

We present a measurement of electron-neutrino interactions from the Fermilab Booster Neutrino Beam using the MicroBooNE liquid argon time projection chamber to address the nature of the excess of low-energy interactions observed by the MiniBooNE collaboration. Three independent electron-neutrino searches are performed across multiple single-electron final states, including an exclusive search for two-body scattering events with a single proton, a semi-inclusive search for pionless events, and a fully inclusive search for events containing all hadronic final states.

Wright Lab Computing Workshop: Data Analysis with Python

This workshop will cover an introduction to Python and the powerful libraries numpy and matplotlib. In the process, we will cover array manipulation, plotting, histogramming, and efficient file IO. Finally, we pull these tools together to analyze some real-world data collected at Wright Lab.
