Kavli Affiliate: Ke Wang | First 5 Authors: He Liu, Ting Zhang, Ke Wang, Fei Gao, Gang Xu | Summary: Hole spins confined in semiconductor quantum dot systems have gained considerable interest for their strong spin-orbit interactions (SOIs) and relatively weak hyperfine interactions. Here we experimentally demonstrate a tunable SOI in a double quantum dot […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Yao Wang, Jiajia Wen, Young Lee, Thomas Devereaux | Summary: Recent experiment has unveiled an anomalously strong electron-electron attraction in one-dimensional copper-oxide chain Ba$_{2-x}$Sr$_x$CuO$_{3+delta}$. While the near-neighbor electron attraction $V$ in the one-dimensional extended Hubbard chain has been examined recently, its effect in the Hubbard […]
Kavli Affiliate: Feng Wang | First 5 Authors: Guangke Chen, Zhe Zhao, Fu Song, Sen Chen, Lingling Fan | Summary: Speaker recognition systems (SRSs) have recently been shown to be vulnerable to adversarial attacks, raising significant security concerns. In this work, we systematically investigate transformation and adversarial training based defenses for securing SRSs. According to […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Nannan Han, Zheng-Dong Luo, Mingwen Zhang, Xiaoqing Chen | Summary: Electrical tuning of second-order nonlinearity in optical materials is attractive to strengthen and expand the functionalities of nonlinear optical technologies, though its implementation remains elusive. Here, we report the electrically tunable second-order nonlinearity in atomically […]
Kavli Affiliate: Jing Wang | First 5 Authors: Mingwen Zhang, Nannan Han, Jing Wang, Zhihong Zhang, Kaihui Liu | Summary: Missing second-order nonlinearity in centrosymmetric graphene overshadows its intriguing optical attribute. Here, we report redox-governed charge doping could effectively break the centrosymmetry of bilayer graphene (BLG), enabling a strong second harmonic generation (SHG) with a […]
Kavli Affiliate: Tomoyuki Abe | Summary:This is the second part of the paper which proves the compatibility of pushforward along a proper morphism of an étale constructible sheaf and the pushforward of its characteristic cycle up to $p$-torsion. In this second part, we show a result which is postponed from the first part because the […]
Kavli Affiliate: Tomoyuki Abe | Summary:We prove the compatibility of pushforward along a proper morphism of an étale constructible sheaf and the pushforward of its characteristic cycle up to $p$-torsion. This was conjectured by Takeshi Saito. For this, we revisit the construction of the characteristic cycle, due to Saito and Beilinson, from more homotopical point […]

Kavli Affiliate: Zheng Zhu | First 5 Authors: Wanhua Li, Xiaoke Huang, Zheng Zhu, Yansong Tang, Xiu Li | Summary: This paper presents a language-powered paradigm for ordinal regression. Existing methods usually treat each rank as a category and employ a set of weights to learn these concepts. These methods are easy to overfit and […]
Kavli Affiliate: Jean Pierre Changeux | Authors: Sophie Shi, Solene N Lefebvre, Laurie Peverini, Adrien H Cerdan, Marc Gielen, Jean-Pierre Changeux, Marco CECCHINI and Pierre-Jean Corringer | Summary: Pentameric ligand-gated ion channel mediate signal transduction at chemical synapses by transiting between resting and open states upon neurotransmitter binding. Here, we investigate the gating transition of […]
