The origin of chirality induced spin selectivity in photo-induced electron transfer

Kavli Affiliate: David T. Limmer | First 5 Authors: Thomas P. Fay, David T. Limmer, , , | Summary: Here we propose a mechanism by which spin polarization can be generated dynamically in chiral molecular systems undergoing photo-induced electron transfer. The proposed mechanism explains how spin polarization emerges in systems where charge transport is dominated […]

Quasiballistic electron transport in cryogenic SiGe HBTs studied using an exact, semi-analytic solution to the Boltzmann equation

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Austin J. Minnich, , , | Summary: Silicon-germanium heterojunction bipolar transistors (HBTs) are of interest as low-noise microwave amplifiers due to their competitive noise performance and low cost relative to III-V devices. The fundamental noise performance limits of HBTs are thus of interest, […]

Attend and select: A segment selective transformer for microblog hashtag generation

Kavli Affiliate: Lihong Wang | First 5 Authors: Qianren Mao, Xi Li, Bang Liu, Shu Guo, Peng Hao | Summary: Hashtag generation aims to generate short and informal topical tags from a microblog post, in which tokens or phrases form the hashtags. These tokens or phrases may originate from primary fragmental textual pieces (e.g., segments) […]

A long-lived solid-state optical quantum memory for high-rate quantum repeaters

Kavli Affiliate: Wolfgang Tittel | First 5 Authors: Mohsen Falamarzi Askarani, Antariksha Das, Jacob H. Davidson, Gustavo C. Amaral, Neil Sinclair | Summary: We argue that long optical storage times are required to establish entanglement at high rates over large distances using memory-based quantum repeaters. Triggered by this conclusion, we investigate the $^3$H$_6$ $leftrightarrow$ $^3$H$_4$ […]
