Platform-agnostic waveguide integration of high-speed photodetectors with evaporated tellurium thin films

Posted by dbos Berkeley

Kavli Affiliate: Ali Javey | First 5 Authors: Geun Ho Ahn, Alexander D. White, Hyungjin Kim, Naoki Higashitarumizu, Felix M. Mayor | Summary: Many attractive photonics platforms still lack integrated photodetectors due to inherent material incompatibilities and lack of process scalability, preventing their widespread deployment. Here we address the problem of scalably integrating photodetectors in […]

Global remapping in granule cells and mossy cells of the mouse dentate gyrus

Posted by klaurent Hopkins

Kavli Affiliate: James Knierim | Authors: Sang Hoon Kim, Douglas GoodSmith, Stephanie J Temme, Fumika Moriya, Guo-li Ming, Kimberly Christian, Hongjun Song and James J Knierim | Summary: SUMMARY Hippocampal place cells exhibit spatially modulated firing, or place fields, which can remap to encode changes in the environment or other variables. Unique among hippocampal subregions, […]

A Spectroscopic Road Map for Cosmic Frontier: DESI, DESI-II, Stage-5

Posted by klaurent Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: David J. Schlegel, Simone Ferraro, Greg Aldering, Charles Baltay, Segev BenZvi | Summary: In this white paper, we present an experimental road map for spectroscopic experiments beyond DESI. DESI will be a transformative cosmological survey in the 2020s, mapping 40 million galaxies and quasars and capturing […]

Light Curves and Event Rates of Axion Instability Supernovae

Posted by klaurent Tokyo

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Takashi J. Moriya, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi | Summary: It was recently proposed that exotic particles can trigger a new stellar instability which is analogous to the e-e+ pair instability if they are produced and reach equilibrium in the stellar plasma. In this […]
