Wright Lab will host 1-hour Environmental Health and Safety (EHS) Shop Orientations. 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.

The Wright Lab community is invited to a weekly meeting on Mondays at 9:30 a.m to hear about and discuss what is going on at the lab.
Abstract: nEXO is a proposed tonne scale liquid xenon time projection chamber which plans to search for the neutrinoless double beta decay (0vbb) of Xe-136. 0vbb is a hypothetical nuclear process in which two neutrons decay into two protons and two electrons, with the notable absence of any neutrinos. Discovery of this hypothetical phenomena would help answer several questions concerning the mass of the neutrino, such as their Majorana nature. nEXO’s proposed detector design would allow it to search for this interaction with a half-life sensitivity greater than 10^{28} yrs.

Abstract: PandaX-4T experiment searches for dark matter particles with a dual-phase time projection chamber holding 4 tonne liquid xenon in the sensitive volume. After the lab and detector construction for more than two years at China Jinping Underground Laboratory, PandaX-4T has begun to take scientific data since the end of the year 2020. In this talk, I will give an overview of the PandaX-4T hardwares and the weakly interacting massive particles (WIMPs) search with our commissioning data, including calibration, signal reconstruction and profile likelihood ratio analysis.
Quantum science is one of five top priority areas identified by Yale University’s Science Strategy. Yale’s Wright Lab is exploring the applications of quantum science and sensing to tests of fundamental physics. This workshop, hosted by Wright Lab as part of Quantum Week at Yale, brings together researchers from Wright Lab, along with keynote speaker Dmitry Budker (Helmholtz Institute Mainz at Johannes Gutenberg University and University of California, Berkeley), to discuss their work and future opportunities in this field.
Artists and scientists with a Yale affiliation are invited to participate in the second annual competition, held at the Yale Wright Laboratory, for teams of artists and scientists to collaborate and create a conceptual model of a quantum concept (to be revealed at the start of the competition) and realize it in either two- or three-dimensional format using materials provided for the competition. This event is part of the programming for Quantum Week at Yale.
Abstract: 21cm observations of the Cosmic Dawn and Epoch of Reionization, via intensity mapping at z>6, offer a unique and exciting probe into the physics of stellar and galaxy formation and even cosmology. A range of instruments across the globe, including the highly targeted HERA experiment, are currently amassing a wealth of data – in which is buried the signature of the birth of the first stars.
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.
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.
