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 […]

When to Sweat the Small Stuff: identifying the most informative events from ground-based gravitational-wave detectors

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Daniel E. Holz, , , | Summary: We explore scaling relations for the information carried by individual events, and how that information accumulates in catalogs like those from ground-based gravitational-wave detectors. For a variety of situations, the larger number of quiet/distant signals dominates the […]

Particle Conversions Beyond the WKB Approximation and Solar-Induced Gravitational Waves from Dark Photon Dark Matter

Kavli Affiliate: Jia Liu | First 5 Authors: Tengyu Ai, Yuxuan He, Jia Liu, Xiaolin Ma, Xiao-Ping Wang | Summary: We investigate the conversion of kinetic mixing dark photon dark matter into gravitational waves within the magnetic field of the Sun. Our study reveals that the WKB approximation is invalid in this scenario. We derive […]
