On the Optimal Feedback Law in Stochastic Optimal Nonlinear Control

Kavli Affiliate: Ran Wang | First 5 Authors: Mohamed Naveed Gul Mohamed, Suman Chakravorty, Raman Goyal, Ran Wang, | Summary: We consider the problem of nonlinear stochastic optimal control. This problem is thought to be fundamentally intractable owing to Bellman’s infamous "curse of dimensionality". We present a result that shows that repeatedly solving an open-loop […]

Anomaly inflow and $p$-form gauge theories

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Chang-Tse Hsieh, Yuji Tachikawa, Kazuya Yonekura, , | Summary: Chiral and non-chiral $p$-form gauge fields have gravitational anomalies and anomalies of Green-Schwarz type. This means that they are most naturally realized as the boundary modes of bulk topological phases in one higher dimensions. We give a systematic […]

High Performance Heat Conductor with Small Spring Constant for Cryogenic Applications

Kavli Affiliate: Takaaki Kajita | First 5 Authors: Tomohiro Yamada, Takayuki Tomaru, Toshikazu Suzuki, Takafumi Ushiba, Nobuhiro Kimura | Summary: We developed a soft and high thermal conductive heat link for cryogenic applications. The measured maximum thermal conductivity was approximately 18500 W/m/K at 10 K. This spring constant was 1/43 of that of a single […]

TESS spots a hot Jupiter with an inner transiting Neptune

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Chelsea X. Huang, Samuel N. Quinn, Andrew Vanderburg, Juliette Becker, Joseph E. Rodriguez | Summary: Hot Jupiters are rarely accompanied by other planets within a factor of a few in orbital distance. Previously, only two such systems have been found. Here, we report the discovery of […]

Dark Energy Survey Identification of A Low-Mass Active Galactic Nucleus at Redshift 0.823 from Optical Variability

Kavli Affiliate: Aaron Roodman | First 5 Authors: Hengxiao Guo, Colin J. Burke, Xin Liu, Kedar A. Phadke, Kaiwen Zhang | Summary: We report the identification of a low-mass AGN, DES J0218$-$0430, in a redshift $z = 0.823$ galaxy in the Dark Energy Survey (DES) Supernova field. We select DES J0218$-$0430 as an AGN candidate […]

The TESS-Keck Survey I: A Warm Sub-Saturn-mass Planet and a Caution about Stray Light in TESS Cameras

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Paul A. Dalba, Arvind F. Gupta, Joseph E. Rodriguez, Diana Dragomir, Chelsea X. Huang | Summary: We report the detection of a Saturn-size exoplanet orbiting HD 332231 (TOI 1456) in light curves from the Transiting Exoplanet Survey Satellite (TESS). HD 332231, an F8 dwarf star with […]
