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: Irfan Siddiqi | First 5 Authors: Hyunseong Kim, Christian Jünger, Alexis Morvan, Edward S. Barnard, William P. Livingston | Summary: As superconducting quantum processors increase in complexity, techniques to overcome constraints on frequency crowding are needed. The recently developed method of laser-annealing provides an effective post-fabrication method to adjust the frequency of superconducting […]
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: Michael Gladders | First 5 Authors: Manuel Solimano, Jorge González-López, Manuel Aravena, Evelyn Johnston, Cristóbal Moya-Sierralta | Summary: Spatially extended halos of Lyman Alpha (Ly$alpha$) emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of these halos is still hampered by the complex radiative […]

Kavli Affiliate: Richard Kessler | First 5 Authors: Martine Lokken, Alexander Gagliano, Gautham Narayan, Renée Hložek, Richard Kessler | Summary: As we observe a rapidly growing number of astrophysical transients, we learn more about the diverse host galaxy environments in which they occur. Host galaxy information can be used to purify samples of cosmological Type […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Michael Zevin, Anya E. Nugent, Susmita Adhikari, Wen-fai Fong, Daniel E. Holz | Summary: The delay time distribution of neutron star mergers provides critical insights into binary evolution processes and the merger rate evolution of compact object binaries. However, current observational constraints on this delay time […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Weiguang Cao, Masahito Yamazaki, Yunqin Zheng, , | Summary: We explore an exact duality in $(2+1)$d between the fermionization of a bosonic theory with a $mathbb{Z}_2$ subsystem symmetry and a fermionic theory with a $mathbb{Z}_2$ subsystem fermion parity symmetry. A typical example is the duality between the […]
