NPA Seminar, Akash Dixit, University of Chicago, "Searching for dark matter with superconducting qubits"

Abstract: Detection mechanisms for low mass bosonic dark matter candidates, such the axion or hidden photon, leverage potential interactions with electromagnetic fields, whereby the dark matter (of unknown mass) on rare occasion converts into a single photon. Current dark matter searches operating at microwave frequencies use a resonant cavity to coherently accumulate the field sourced by the dark matter and a near standard quantum limited (SQL) linear amplifier to read out the cavity signal.

NPA Seminar, Christopher Swank, CalTech, “Advanced Critical Spin Dressing”

Abstract: The neutron electric dipole moment (nEDM) experiment at the Spallation Neutron Source (SNS) will measure the nEDM via interaction with Helium-3. Ultimate sensitivity will be reached in that apparatus by using the critical spin dressing technique. Critical spin dressing is the application of an off-resonant oscillatory field that dresses the neutron and Helium-3 spins to have the same effective Larmor precession. Advanced critical spin dressing techniques are in development that can provide high sensitivity measurements of magnetic field gradients with a large dynamic range.

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.

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.

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, Lee Hagaman & Giacomo Scanavini, Yale University, "First Test of the MiniBooNE Low Energy Excess Under a Single-Photon Hypothesis in the MicroBooNE Experiment"

Abstract TBA
In-person attendance will be capped at 20 people on a first-come, first-served basis, according to the current Yale policies.
