Kavli Affiliate: Joel E. Moore | First 5 Authors: Yan-Qi Wang, Michał Papaj, Joel E. Moore, , | Summary: Gapless helical edge modes are a hallmark of the quantum spin Hall effect. Protected by time-reversal symmetry, each edge contributes a quantized zero-temperature conductance quantum $G_0 equiv e^2/h$. However, the experimentally observed conductance in WTe$_2$ decreases […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Yongli Zhu, Xiang Zhang, Renchang Dai | Summary: This paper proposes an electronic circuit simulator-based method to accelerate the power system transient simulation, where the modeling of a generic HVDC (High Voltage Direct Current) system is focused. The electronic circuit simulation equations and the backward differentiation formula […]

Kavli Affiliate: Feng Wang | First 5 Authors:Ruoqi Wang, Zhuoyang Chen, Qiong Luo, Feng Wang | Summary: In radio astronomy, signals from radio telescopes are transformed into images of observed celestial objects, or sources. However, these images, called dirty images, contain real sources as well as artifacts due to signal sparsity and other factors. Therefore, […]

Kavli Affiliate: Feng Wang | First 5 Authors: Guorui Chen, Ya-Hui Zhang, Aaron Sharpe, Zuocheng Zhang, Shaoxin Wang | Summary: Wigner crystals are predicted as the crystallization of the dilute electron gas moving in a uniform background when the electron-electron Coulomb energy dominates the kinetic energy. The Wigner crystal has previously been observed in the […]

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Xiaohua Zhu | Summary: We prove that the Gromov-Hausdorff limit of K”ahler-Ricci flow on a $mathbf G$-spherical Fano manifold $X$ is a $mathbf G$-spherical $mathbb Q$-Fano variety $X_{infty}$, which admits a (singular) K”ahler-Ricci soliton. Moreover, the $mathbf G$-spherical variety structure of $X_{infty}$ can be constructed […]

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Galit Cohen, Jonah B. Haber, Jeffrey B. Neaton, Diana Y. Qiu, Sivan Refaely-Abramson | Summary: Non-radiative exciton relaxation processes are critical for energy transduction efficiencies in optoelectronic materials, but how these processes are connected to the underlying crystal structure and its associated electron, exciton, and phonon […]

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Nicholas Walker, John Dagdelen, Kevin Cruse, Sanghoon Lee, Samuel Gleason | Summary: Although gold nanorods have been the subject of much research, the pathways for controlling their shape and thereby their optical properties remain largely heuristically understood. Although it is apparent that the simultaneous presence of and […]
