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: 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.
We apply analytic bootstrap techniques to study correlators of local operators in the presence of an extended object or “defect”. After reviewing the general setup, we focus on N=4 SYM at strong coupling.
Mariano Sigman is one of the most outstanding neuroscientists in the world, with over 150 publications in the most prestigious scientific journals. He is also passionate about experimentation and has worked with magicians, chess masters, musicians, athletes and visual artists to bring his knowledge of neuroscience to different aspects of human culture and apply it in different contexts. He has participated twice (2016 and 2017) in the TED global events in Vancouver, the second with Dan Ariely.
Abstract: The charge resistivity/conductivity can take universal values in various scenarios of two-dimensional condensed matter systems. Well-known examples of universal resistivity include 2+1d quantum critical points, (fractional) quantum Hall effects, the criterion of two-dimensional “bad metal”, and the universal resistivity jump predicted at the interaction-driven metal-insulator transition.
