Kavli Affiliate: Zheng Zhu | First 5 Authors: Yuchu Jiang, Yuchu Jiang, , , | Summary: The rapid advancement of AI has expanded its capabilities across domains, yet introduced critical technical vulnerabilities, such as algorithmic bias and adversarial sensitivity, that pose significant societal risks, including misinformation, inequity, security breaches, physical harm, and eroded public trust. […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Subaru Fujisawa, Subaru Fujisawa, , , | Summary: We explore the indirect detection of sterile neutrino dark matter within the gauged $U(1)_B-L$ extension of the Standard Model, in which three right-handed neutrinos account for neutrino masses, the baryon asymmetry, and dark matter. Focusing on the MeV mass […]
Kavli Affiliate: Leon Balents | First 5 Authors: Chuang Chen, Chuang Chen, , , | Summary: We design a lattice model of non-compact U(1) gauge field coupled to fermions with a flavor chemical potential and solve it with large-scale determinant quantum Monte Carlo simulations. For zero flavor chemical potential, the model realizes three-dimensional quantum electrodynamics […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Jaume Garriga, Jaume Garriga, , , | Summary: Spectator fields which provide additional tensor degrees of freedom, on top of the standard metric tensor perturbations, can produce significant amounts of gravitational waves (GWs). Employing the effective field theory approach for spin-2 fields, we find a universal prediction […]
Kavli Affiliate: Sara Seager | First 5 Authors: , , , , | Summary: The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to selection biases, many exoplanets under study are planets deemed inhospitable because their surfaces are too warm […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, Lihong V. Wang, , , | Summary: After publishing the derivation from the classical Bloch equation to the quantum von Neumann equation to the Schr"odinger–Pauli equation for spin-1/2, we proposed renaming the Bloch equation to the Majorana–Bloch equation because Majorana’s work predated Bloch’s […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Chaojun Ni, Chaojun Ni, , , | Summary: Reinforcement learning for training end-to-end autonomous driving models in closed-loop simulations is gaining growing attention. However, most simulation environments differ significantly from real-world conditions, creating a substantial simulation-to-reality (sim2real) gap. To bridge this gap, some approaches utilize scene reconstruction […]

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: LDMX Collaboration, LDMX Collaboration, , , | Summary: The Light Dark Matter eXperiment (LDMX) is proposed to employ a thin tungsten target and a multi-GeV electron beam to carry out a missing momentum search for the production of dark matter candidate particles. We study the sensitivity for […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ryan Wong, Ryan Wong, , , | Summary: From professional research to everyday planning, many tasks are bottlenecked by wide-scale information seeking, which is more repetitive than cognitively complex. With the rapid development of Large Language Models (LLMs), automated search agents powered by LLMs offer a promising […]
