The joint automated repository for various integrated simulations (JARVIS) for data-driven materials design

November 12, 2020
Author(s)
Kamal Choudhary, Kevin Garrity, Andrew C. Reid, Brian DeCost, Adam Biacchi, Angela R. Hight Walker, Zachary Trautt, Jason Hattrick-Simpers, Aaron Kusne, Andrea Centrone, Albert Davydov, Francesca Tavazza, Jie Jiang, Ruth Pachter, Gowoon Cheon, Evan Reed, Ankit Agrawal, Xiaofeng Qian, Vinit Sharma, Houlong Zhuang, Sergei Kalinin, Ghanshyam Pilania, Pinar Acar, Subhasish Mandal, David Vanderbilt, Karin Rabe
The Joint Automated Repository for Various Integrated Simulations (JARVIS) is an integrated infrastructure to accelerate materials discovery and design using density functional theory (DFT), classical force-fields (FF), and machine learning (ML) techniques

Reduction of charge offset drift using plasma oxidized aluminum in SETs

October 26, 2020
Author(s)
Yanxue Hong, Ryan Stein, Michael Stewart, Neil M. Zimmerman, Joshua M. Pomeroy
Aluminum oxide (AlOx)-based single-electron transistors (SETs) fabricated in ultra-high vacuum (UHV) chambers using in situ plasma oxidation show excellent stabilities over more than a week, enabling applications as tunnel barriers, capacitor dielectrics

Quantum Randomness from Probability Estimation with Classical Side Information

September 22, 2020
Author(s)
Emanuel Knill, Yanbao Zhang, Peter L. Bierhorst
We develop a framework for certifying randomness from Bell-test trials based on directly estimating the probability of the measurement outcomes with adaptive test supermartingales. The number of trials need not be predetermined, and one can stop performing

Calibration of free-space and fiber-coupled single-photon detectors

September 14, 2020
Author(s)
Thomas Gerrits, Alan L. Migdall, Joshua C. Bienfang, John H. Lehman, Sae Woo Nam, Oliver T. Slattery, Jolene D. Splett, Igor Vayshenker, Chih-Ming Wang
We present our measurements of the detection efficiency of free-space and fiber-coupled single- photon detectors at wavelengths near 851 nm and 1533.6 nm. We investigate the spatial uniformity of one free-space-coupled silicon single-photon avalanche diode

Terahertz Electromagnetically Induced Transparency in Cesium Atoms

September 14, 2020
Author(s)
Sumit Bhushan, Oliver T. Slattery, Xiao Tang, Lijun Ma
We outline a proposal to realize Electromagnetically Induced Transparency (EIT) with the potential to store Terahertz (THz) optical pulses in Cesium atoms. Such a system, when experimentally realized, has a potential to make Quantum Communication possible

Mechanical Quantum Sensing in the Search for Dark Matter

August 13, 2020
Author(s)
Jacob Taylor, Gadi Afek, Sunil Bhave, Daniel Carney, Gordan Krnjaic, David Moore, Robinjeet Singh, Cindy Regal, Benjamin M. Brubaker, Andrew Geraci, Jonathan D. Cripe, Sohitri Ghosh, Jack Harris, Anson Hook, Jonathan Kunjummen, Rafael Lang, Li Tongcang, Tongyan Lin, Zhen Liu, Joseph Lykken, Lorenzo Magrini, Jack Manley, Nobuyuki Matsumoto, Alissa Monte, Fernando Monteiro, Thomas Purdy, C. J. Riedel, Swati Singh, Kanupriya Sinha, Juehang Qin, Dalziel Wilson, Yue Zhao
Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals produced by this dark matter
