Emergent gauge flux and spin ordering in magnetized triangular spin liquids: Applications to Hofstadter-Hubbard model
Jiahao Yang, Hao Tian, Si-Yu Pan +1
Motivated by recent progress in moiré superlattices and spin-1/2 triangular-lattice antiferromagnets, we study how orbital magnetic flux and Zeeman coupling compete or cooperate in…
FinMMDocR: Benchmarking Financial Multimodal Reasoning with Scenario Awareness, Document Understanding, and Multi-Step Computation
Zichen Tang, Haihong E, Rongjin Li +18
We introduce FinMMDocR, a novel bilingual multimodal benchmark for evaluating multimodal large language models (MLLMs) on real-world financial numerical reasoning. Compared to exis…
Isolation-based Spherical Ensemble Representations for Anomaly Detection
Yang Cao, Sikun Yang, Hao Tian +4
Anomaly detection is a critical task in data mining and management with applications spanning fraud detection, network security, and log monitoring. Despite extensive research, exi…
Magnetotransport across Weyl semimetal grain boundaries
Haoyang Tian, Vatsal Dwivedi, Adam Yanis Chaou +1
A clean interface between two Weyl semimetals features a universal, field-linear tunnel magnetoconductance of per magnetic flux quantum, where $N_\mathrm{ho}…
