Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ruo Xi Yang, Matthew K. Horton, Jason Munro, Kristin A. Persson, | Summary: An optical absorption spectrum constitutes one of the most fundamental material characteristics, with relevant applications ranging from material identification to energy harvesting and optoelectronics. However, the database of both experimental and computational spectra […]
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: Andrey Kravtsov | First 5 Authors: Khanh Pham, Andrey Kravtsov, Viraj Manwadkar, , | Summary: We examine the spatial distribution and orbital pole correlations of satellites in a suite of zoom-in high-resolution dissipationless simulations of Miky Way (MW) sized haloes. We use the measured distribution to estimate the incidence of satellite configurations as […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Philip Mansfield, Yunchong Wang, Xiaolong Du, Susmita Adhikari | Summary: We present Symphony, a compilation of $262$ cosmological, cold dark matter-only zoom-in simulations spanning four decades of host halo mass, from $10^{11}~M_{mathrm{odot}}$ to $10^{15}~M_{mathrm{odot}}$. This compilation includes three existing simulation suites at the […]
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 […]

This paper develops its finite-time […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Sergey S. Tsygankov, Victor Doroshenko, Juri Poutanen, Jeremy Heyl, Alexander A. Mushtukov | Summary: Cen X-3 is the first X-ray pulsar discovered 50 years ago. Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with propagation of […]
Kavli Affiliate: Mikhail Kapranov | First 5 Authors: Mikhail Kapranov, Vadim Schechtman, , , | Summary: We consider the space Z(C,L) of 0-cycles on the complex line C with coefficients in a commutative monoid L subject to certain conditions. Such spaces include the symmetric products (for L=Z_+) and the Ran space (for L=T={ True, False} […]
