Kavli Affiliate: Ke Wang | First 5 Authors: Ji Li, Ke Wang, Qiliang Wu, Qing Yu, | Summary: A wave front and a wave back that spontaneously connect two hyperbolic equilibria, known as a heteroclinic wave loop, give rise to periodic waves with arbitrarily large spatial periods through the heteroclinic bifurcation. The nonlinear stability of […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Luigi Pacciani, Dawoon E. Kim, Riccardo Middei, Herman L. Marshall, Alan P. Marscher | Summary: We report the Imaging X-ray Polarimetry Explorer (IXPE) polarimetric and simultaneous multiwavelength observations of the high-energy-peaked BL Lacertae (HBL) object 1ES 1959+650, performed in 2022 October and 2023 August. In 2022 […]
Kavli Affiliate: Jia Liu | First 5 Authors: Changqing Li, Ran Xia, Yutai Zhao, Yifang Li, Jia Liu | Summary: Mamyshev oscillators (MOs), a novel class of passively mode-locked fiber lasers, serve as an excellent platform to explore complex nonlinear dynamics, ranging from localized sturctures to chaos. Despite their versatility, achieving self-starting mode-locking remains a […]
Kavli Affiliate: Birgitta Whaley | First 5 Authors: Oskar Leimkuhler, K. Birgitta Whaley, , , | Summary: We prove classical simulation hardness, under the generalized $mathsf{P}neqmathsf{NP}$ conjecture, for quantum circuit families with applications in near-term quantum chemical ground state estimation. The proof exploits a connection to particle number conserving matchgate circuits with fermionic magic state […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Haoyang Qi, Renxin Xu, , , | Summary: This article discusses strong nuggets (SNs) which means strong interaction condensed matter clusters with a mass of about $10^6,$g. They may originate from the early universe, supernova, pulsar merger event, and so on. Depending on the equation of state, […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Xinlei Zhou, Rihao Li, Meng Hu, Wenhui Wu | Summary: Despite the remarkable success of deep neural networks (DNNs), the security threat of adversarial attacks poses a significant challenge to the reliability of DNNs. By introducing randomness into different parts of DNNs, stochastic methods can […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Sunao Sugiyama, Toshiki Kurita, | Summary: Different cosmological probes, such as primary cosmic microwave background (CMB) anisotropies, CMB lensing, and cosmic shear, are sensitive to the primordial power spectrum (PPS) over different ranges of wavenumbers. In this paper, we combine the cosmic shear […]
Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Chao Li, Taolei Wang, Jinyang Guo, Hanzhang Yang | Summary: The growing scale of data requires efficient memory subsystems with large memory capacity and high memory performance. Disaggregated architecture has become a promising solution for today’s cloud and edge computing for its scalability and elasticity. […]
Kavli Affiliate: Long Zhang | First 5 Authors: Long Zhang, Zhongzhu Jiang, Yugang Zhang, Jing Zhang, Aifeng Wang | Summary: Two-dimensional (2D) magnetic materials have attracted considerable interest owing to their potential applications in spintronics and fundamental investigations into low-dimensional magnetism. Cr2Te3, a quasi 2D non van der Waals magnet, exhibits a complex magnetic phase […]
Kavli Affiliate: Zhuo Li | First 5 Authors: Xuying Li, Zhuo Li, Yuji Kosuga, Victor Bian, | Summary: Aligning large language models (LLMs) with human values and safety constraints is challenging, especially when objectives like helpfulness, truthfulness, and avoidance of harm conflict. Reinforcement Learning from Human Feedback (RLHF) has achieved notable success in steering models, […]
