Kavli Affiliate: Austin J. Minnich | First 5 Authors: Nachiket R. Naik, Bekari Gabritchidze, Justin H. Chen, Jacob Kooi, Kieran A. Cleary | Summary: The deviations of cryogenic collector current-voltage characteristics of SiGe heterojunction bipolar transistors (HBTs) from ideal drift-diffusion theory have been a topic of investigation for many years. Recent work indicates that direct […]

Kavli Affiliate: Wei Gao | First 5 Authors: Li Kai, Li Ning, Zhang Wei, Gao Ming, | Summary: Based on the traditional VAE, a novel neural network model is presented, with the latest molecular representation, SELFIES, to improve the effect of generating new molecules. In this model, multi-layer convolutional network and Fisher information are added […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, Aurélie Champagne, Jonah B. Haber, Supavit Pokawanvit, Joeson Wong | Summary: Monolayer transition metal dichalcogenide (TMDC) semiconductors exhibit strong excitonic optical resonances which serve as a microscopic, non-invasive probe into their fundamental properties. Like the hydrogen atom, such excitons can exhibit an entire Rydberg […]

Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Maodong Gao, Yan Yu, Heming Wang, Warren Jin | Summary: Soliton microcombs are helping to advance the miniaturization of a range of comb systems. These combs mode lock through the formation of short temporal pulses in anomalous dispersion resonators. Here, a new microcomb is demonstrated […]

Kavli Affiliate: Kerry Vahala | First 5 Authors: Qing-Xin Ji, Warren Jin, Lue Wu, Yan Yu, Zhiquan Yuan | Summary: Normal group velocity dispersion (GVD) microcombs offer high comb line power and high pumping efficiency compared to bright pulse microcombs. The recent demonstration of normal GVD microcombs using CMOS-foundry-produced microresonators is an important step towards […]

Kavli Affiliate: Andrei Faraon | First 5 Authors: Conner Ballew, Gregory Roberts, Andrei Faraon, , | Summary: The ideal imaging system would efficiently capture information about all fundamental properties light: intensity, direction, wavelength, and polarization. Most common imaging systems only map the spatial degrees of freedom of light onto a two dimensional image sensor, with […]

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Ramon Gao, Michael D. Kelzenberg, Harry A. Atwater, , | Summary: Lightsail spacecraft, propelled to relativistic velocities via photon pressure using high power density laser radiation, offer a potentially new route to space exploration within and beyond the solar system, extending to interstellar distances. Such missions […]

Kavli Affiliate: Morteza Gharib | First 5 Authors: Peter I Renn, Cong Wang, Sahin Lale, Zongyi Li, Anima Anandkumar | Summary: We apply Fourier neural operators (FNOs), a state-of-the-art operator learning technique, to forecast the temporal evolution of experimentally measured velocity fields. FNOs are a recently developed machine learning method capable of approximating solution operators […]
