Status report towards implementation of a Compton polarimeter at BEPCII
Mengyu Su, Zhe Duan, Jie Gao +26
Precision beam polarization measurements based on Compton polarimeters are essential for the physics program of future high-energy colliders. In order to prepare for these and to e…
USM: Unbiased Survey Modeling for Limiting Negative User Experiences in Recommendation Systems
Chenghui Yu, Peiyi Li, Haoze Wu +3
Reducing negative user experiences is essential for the success of recommendation platforms. Exposing users to inappropriate content could not only adversely affect users' psycholo…
Emergent collective intelligence from massive-agent cooperation and competition
Hanmo Chen, Stone Tao, Jiaxin Chen +6
Inspired by organisms evolving through cooperation and competition between different populations on Earth, we study the emergence of artificial collective intelligence through mass…
When Rules Fall Short: Agent-Driven Discovery of Emerging Content Issues in Short Video Platforms
Chenghui Yu, Hongwei Wang, Junwen Chen +5
Trends on short-video platforms evolve at a rapid pace, with new content issues emerging every day that fall outside the coverage of existing annotation policies. However, traditio…
Measurement of the fine-structure constant as a test of the Standard Model
Richard H. Parker, Chenghui Yu, Weicheng Zhong +2
Measurements of the fine-structure constant alpha require methods from across subfields and are thus powerful tests of the consistency of theory and experiment in physics. Using th…
High-resolution atom interferometers with suppressed diffraction phases
Brian Estey, Chenghui Yu, Holger Müller +2
We experimentally and theoretically study the diffraction phase of large-momentum transfer beam splitters in atom interferometers based on Bragg diffraction. We null the diffractio…
Laser frequency stabilization by combining modulation transfer and frequency modulation spectroscopy
Fei Zi, Xuejian Wu, Weicheng Zhong +5
We present a hybrid laser frequency stabilization method combining modulation transfer spectroscopy (MTS) and frequency modulation spectroscopy (FMS) for the cesium D2 transition.…
Seeking Common Ground While Reserving Differences: Multiple Anatomy Collaborative Framework for Undersampled MRI Reconstruction
Jiangpeng Yan, Chenghui Yu, Hanbo Chen +4
Recently, deep neural networks have greatly advanced undersampled Magnetic Resonance Image (MRI) reconstruction, wherein most studies follow the one-anatomy-one-network fashion, i.…
Controlling the Multiport Nature of Bragg Diffraction in Atom Interferometry
Richard H Parker, Chenghui Yu, Brian Estey +3
Bragg diffraction has been used in atom interferometers because it allows signal enhancement through multiphoton momentum transfer and suppression of systematics by not changing th…
Physics Briefing Book: Input for the 2026 update of the European Strategy for Particle Physics
Jorge de Blas, Monica Dunford, Emanuele Bagnaschi +127
The European Strategy for Particle Physics (ESPP) reflects the vision and presents concrete plans of the European particle physics community for advancing human knowledge in fundam…
Benchmarking Robustness and Generalization in Multi-Agent Systems: A Case Study on Neural MMO
Yangkun Chen, Joseph Suarez, Junjie Zhang +18
We present the results of the second Neural MMO challenge, hosted at IJCAI 2022, which received 1600+ submissions. This competition targets robustness and generalization in multi-a…
Offset Simultaneous Conjugate Atom Interferometers
Weicheng Zhong, Richard H. Parker, Zachary Pagel +2
Correlating the signals from simultaneous atom interferometers has enabled some of the most precise determinations of fundamental constants. Here, we show that multiple interferome…
Limits on Lorentz violation in gravity from worldwide superconducting gravimeters
Cheng-Gang Shao, Ya-Fen Chen, Rong Sun +5
We investigated Lorentz violation through anisotropy of gravity using a worldwide array of 12 superconducting gravimeters. The Lorentz-violating signal is extracted from the differ…
