Analysis of Crab X-ray Polarization using Deeper IXPE Observations

Kavli Affiliate: Nicola Omodei | First 5 Authors: Josephine Wong, Tsunefumi Mizuno, Niccoló Bucciantini, Roger W. Romani, Yi-Jung Yang | Summary: We present Crab X-ray polarization measurements using IXPE data with a total exposure of 300ks, three times more than the initial 2022 discovery paper. Polarization is detected in three times more pulsar phase bins, […]

Edge Optical Effect as Probe of Chiral Topological Superconductor

Kavli Affiliate: Jing Wang | First 5 Authors: Linghao Huang, Jing Wang, , , | Summary: We study the optical effect of chiral topological superconductors in two dimensions. The linear optical response from chiral Bogoliubov edge modes in clean superconductors has in-gap resonances, which is originated from the transitions within the edge particle-hole pair bands. […]

Engineering Fractional Chern Insulators through Periodic Strain in Monolayer Graphene and Transition Metal Dichalcogenides

Kavli Affiliate: Zheng Zhu | First 5 Authors: Yuchen Liu, Zheng Zhu, , , | Summary: We propose the realization of interaction-driven insulators in periodically strained monolayer graphene and transition metal dichalcogenides (TMDs). By analyzing the tunable band structure and band geometry via strain, and performing extensive many-body exact diagonalization of a realistic model, we […]

Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities

Kavli Affiliate: Ke Wang | First 5 Authors: Weikang Li, Mengyao Hu, Ke Wang, Shibo Xu, Zhide Lu | Summary: Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell nonlocality from experimental data. Here, we present […]

Turning Generative Models Degenerate: The Power of Data Poisoning Attacks

Kavli Affiliate: Yi Zhou | First 5 Authors: Shuli Jiang, Swanand Ravindra Kadhe, Yi Zhou, Farhan Ahmed, Ling Cai | Summary: The increasing use of large language models (LLMs) trained by third parties raises significant security concerns. In particular, malicious actors can introduce backdoors through poisoning attacks to generate undesirable outputs. While such attacks have […]
