NPA Seminar: Jonghee Yoo, Seoul National University, "Searching for invisible axion dark matter with an 18T magnet haloscope"

Astrophysical observation indicates that 68% of the Universe is made up of dark energy, 27% is dark matter, and the rest 5% is ordinary matter. Therefore, probing the dark components of the Universe is the most prominent subject in modern particle physics. One of the strong candidates of dark matter is the hypothetical particle called axions. The axion has been postulated to solve the strong-CP problem in quantum chromodynamics. The axion is also an ideal dark matter candidate who would have been produced during the Big Bang.

NPA Seminar: Karl van Bibber, UC Berkeley, "ALPHA – A Search for the Post-Inflation Axion"

The axion represents both the most natural solution to the Strong-CP problem and a compelling candidate to constitute the dark matter of the Universe. The most sensitive experiments searching for axion dark matter are based on the resonant conversion of axions to photons within a microwave cavity permeated by a magnetic field.

Dissertation Defense: Sumita Ghosh, Yale University, "Harnessing HAYSTAC for Hidden Photons and Advancing Rydberg Atom-based Axion Detection"

Dark matter is the name that we give to the 85% of matter in the universe that interacts via gravity but negligibly with any of the other known forces. One compelling model for dark matter is the axion, as it simultaneously solves the existence of dark matter and the strong CP problem in QCD. Axions can interact with a strong magnetic field through the Primakoff effect, wherein the axion can spontaneously convert into a photon in the presence of a strong magnetic field.

YQI Seminar: Oriol Romero-Isart, Institute for the Quantum Optics and Quantum Information, "Levitated Nanoparticles in Macroscopic Quantum Superpositions: Pushing the Boundaries of Quantum Mechanics"

In recent years, advancements in optically levitated nanoparticles have enabled the cooling of their center-of-mass motion to the quantum ground state. As a result, a nanoparticle, which comprises billions of atoms, becomes delocalized over picometer scales. This talk aims to explore the challenges and requirements of achieving a macroscopic quantum superposition of a nanoparticle, in which the center-of-mass position is delocalized over orders of magnitude larger scales.

NPA Seminar: Berndt Mueller, Duke/Yale, "What can energy-energy correlators tell us?"

Energy-energy correlators (EEC) have been proposed as new powerful tools to explore the substructure of QCD jets. Compared with other tools that are used to characterize jet substructure they have the advantage of being firmly anchors in QCD, and their scale evolution is well defined and calculable in perturbative QCD. Experimental data indicate a rapid transition from a regime (at large relative angles) that is well described by perturbative parton splitting to a regime (at small relative angles) where the EECs are described by statistical emission of hadrons.

Introduction to the Advanced Prototyping Center

In this workshop we will cover the equipment available at the Wright Lab Advanced Prototyping Center and how to get started designing parts. Basics of CNC laser and abrasive water jet cutting will be included, as well as an introduction to 3D printing. No prior experience is required, but having an idea for a project that you may want to get started on would be great. We will start off with a classroom presentation and then have a quick tour of the facilities.

Summer 2023 EHS Orientation for Wright Lab Research Shop Users

Wright Lab will host a 1-hour Environmental Health and Safety (EHS) Shop Orientation on Tuesday, June 13 at 10:00 a.m. The EHS shop orientation is offered each semester and is required to be taken once by anyone who would like to gain access and make use of the research and teaching shops at Wright Lab.
