Search for axion-like dark matter with spin-based amplifiers

no code implementations2 Feb 2021 Min Jiang, Haowen Su, Antoine Garcon, Xinhua Peng, Dmitry Budker

Here, we demonstrate a new quantum sensor to search for ALPs in the mass range that spans about two decades from 8. 3 feV to 744 feV.

Deep Neural Networks to Recover Unknown Physical Parameters from Oscillating Time Series

no code implementations11 Jan 2021 Antoine Garcon, Julian Vexler, Dmitry Budker, Stefan Kramer

We show that, because DNNs can find useful abstract feature representations, they can be used when prior knowledge about the signal-generating process exists, but is not complete, as it is particularly the case in "new-physics" searches.

Search for axion-like dark matter using solid-state nuclear magnetic resonance

no code implementations4 Jan 2021 Deniz Aybas, Janos Adam, Emmy Blumenthal, Alexander V. Gramolin, Dorian Johnson, Annalies Kleyheeg, Samer Afach, John W. Blanchard, Gary P. Centers, Antoine Garcon, Martin Engler, Nataniel L. Figueroa, Marina Gil Sendra, Arne Wickenbrock, Matthew Lawson, Tao Wang, Teng Wu, Haosu Luo, Hamdi Mani, Philip Mauskopf, Peter W. Graham, Surjeet Rajendran, Derek F. Jackson Kimball, Dmitry Budker, Alexander O. Sushkov

We calibrated the detector and characterized the excitation spectrum and relaxation parameters of the nuclear spin ensemble with pulsed magnetic resonance measurements in a 4. 4 T magnetic field.

Probing fast oscillating scalar dark matter with atoms and molecules

no code implementations2 Dec 2020 Dionysios Antypas, Oleg Tretiak, Ke Zhang, Antoine Garcon, Gilad Perez, Mikhail G. Kozlov, Stephan Schiller, Dmitry Budker

We discuss the WReSL experiment, report on progress towards improved measurements of rapid fundamental constant variations, and discuss the planned extension of the work to molecules, in which rapid variations of the nuclear mass can be sensitively searched for.
