Kavli Affiliate: Tom Abel | First 5 Authors: Lehman H. Garrison, Tom Abel, Daniel J. Eisenstein, , | Summary: We use the $k$-nearest neighbor probability distribution function ($k$NN-PDF, Banerjee & Abel 2021) to assess convergence in a scale-free $N$-body simulation. Compared to our previous two-point analysis, the $k$NN-PDF allows us to quantify our results in […]
Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Jie Chen, Cédric Richard, Wentao Shi, Qunfei Zhang | Summary: The recursive least-squares algorithm with $ell_1$-norm regularization ($ell_1$-RLS) exhibits excellent performance in terms of convergence rate and steady-state error in identification of sparse systems. Nevertheless few works have studied its stochastic behavior, in particular its […]
Kavli Affiliate: Herre Van Der Zant | First 5 Authors: Eugenia Pyurbeeva, Chunwei Hsu, David Vogel, Christina Wegeberg, Marcel Mayor | Summary: Single molecules are nanoscale thermodynamic systems with few degrees of freedom. Thus, the knowledge of their entropy can reveal the presence of microscopic electron transfer dynamics, that are difficult to observe otherwise. Here, […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Pengcheng Ding, Zhuo Li, Cristina Mattioli, Wenlong E | Summary: Transition metal carbides have sparked unprecedented enthusiasm as high-performance catalysts in recent years. Still, the catalytic properties of copper (Cu) carbide remain unexplored. By introducing subsurface carbon (C) to Cu(111), displacement reaction of proton in […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Shaoshan Wang, Zhuo Li, Pengcheng Ding, Cristina Mattioli, Wujun Huang | Summary: On-surface synthesis (OSS) involving relatively high energy barriers remains challenging due to a typical dilemma: firm molecular anchor is required to prevent molecular desorption upon the reaction, whereas sufficient lateral mobility is crucial for subsequent […]
