Kavli Affiliate: George Efstathiou | Summary:Weak galaxy lensing surveys have consistently reported low values of the $S_8$ parameter compared to the $textitPlanck ΛrmCDM$ cosmology. Amon & Efstathiou (2022) used KiDS-1000 cosmic shear measurements to propose that this tension can be reconciled if the matter fluctuation spectrum is suppressed more strongly on non-linear scales than assumed […]
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. […]
