Kavli Affiliate: Rana X. Adhikari | First 5 Authors: Tuvia Gefen, Rajashik Tarafder, Rana X. Adhikari, Yanbei Chen, | Summary: Current laser-interferometric gravitational wave detectors suffer from a fundamental limit to their precision due to the displacement noise of optical elements contributed by various sources. Several schemes for Displacement-Noise Free Interferometers (DFI) have been proposed […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Bekari Gabritchidze, Kieran A. Cleary, Anthony C. Readhead, Austin J. Minnich, | Summary: We report the on-wafer characterization of $S$-parameters and microwave noise temperature ($T_{50}$) of discrete metamorphic InGaAs high electron mobility transistors (mHEMTs) at 40 K and 300 K and over a range of drain-source […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Yue Wang, Yi Zhou, Shaofeng Zou, , | Summary: Greedy-GQ with linear function approximation, originally proposed in cite{maei2010toward}, is a value-based off-policy algorithm for optimal control in reinforcement learning, and it has a non-linear two timescale structure with the non-convex objective function. This paper develops its tightest […]
Kavli Affiliate: Anna Frebel | First 5 Authors: Jeremy Kowkabany, Rana Ezzeddine, Corinne Charbonnel, Ian U. Roederer, Ella Xi Wang | Summary: We present the discovery of 2MASS J05241392-0336543 (hereafter J0524-0336), a very metal-poor ([Fe/H]=-2.43 +- 0.16), highly r-process-enhanced ([Eu/Fe]= +1.34 +- 0.10) Milky Way halo field red giant star, with an ultra high Li […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhuo Chen, Jie Liu, Yubo Hu, Lei Wu, Yajin Zhou | Summary: In recent years, the underground economy is proliferating in the mobile system. These underground economy apps (UEware) make profits from providing non-compliant services, especially in sensitive areas such as gambling, pornography, and loans. Unlike traditional […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Brittany E. Miles, Beth A. Biller, Polychronis Patapis, Kadin Worthen, Emily Rickman | Summary: We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a $<$20 M$_mathrm{Jup}$ widely separated ($sim$8arcsec, a = 150 au), young, planetary-mass companion that shares photometric colors […]
Kavli Affiliate: Simon Groblacher | First 5 Authors: Zhi-Yuan Fan, Liu Qiu, Simon Gröblacher, Jie Li, | Summary: Microwave-optics entanglement is a vital component for building hybrid quantum networks. Here, a new mechanism for preparing stationary entanglement between microwave and optical cavity fields in a cavity optomagnomechanical system is proposed. It consists of a magnon […]
Kavli Affiliate: Kent D. Irwin | First 5 Authors: Cyndia Yu, Zeeshan Ahmed, Josef C. Frisch, Shawn W. Henderson, Max Silva-Feaver | Summary: We describe the newest generation of the SLAC Microresonator RF (SMuRF) electronics, a warm digital control and readout system for microwave-frequency resonator-based cryogenic detector and multiplexer systems such as microwave SQUID multiplexers […]
