Conductivity of two-dimensional narrow gap semiconductors subjected to strong Coulomb disorder
Yi Huang, Yanjun He, Brian Skinner +1
In the ideal disorder-free situation, a two-dimensional band gap insulator has an activation energy for conductivity equal to half the band gap . But transport experiments usua…
SPORTU: A Comprehensive Sports Understanding Benchmark for Multimodal Large Language Models
Haotian Xia, Zhengbang Yang, Junbo Zou +10
Multimodal Large Language Models (MLLMs) are advancing the ability to reason about complex sports scenarios by integrating textual and visual information. To comprehensively evalua…
Detection of long-range entanglement in gapped quantum spin liquids by local measurements
Shi Feng, Yanjun He, Nandini Trivedi
Topological order, reflected in long range patterns of entanglement, is quantified by the topological entanglement entropy (TEE) . We show that for gapped quantum spin liquids…
Probabilistic Population Projections for Countries with Generalized HIV/AIDS Epidemics
David J. Sharrow, Jessica Godwin, Yanjun He +2
The United Nations (UN) issued official probabilistic population projections for all countries to 2100 in July 2015. This was done by simulating future levels of total fertility an…
Electronic and spin dynamics in the insulating iron pnictide NaFeCuAs
Shunhong Zhang, Yanjun He, Jia-Wei Mei +2
NaFeCuAs represents a rare exception in the metallic iron pnictide family, in which a small insulating gap is opened. Based on first-principles study, we provide a…
Multiplicative Coevolution Regression Models for Longitudinal Networks and Nodal Attributes
Yanjun He, Peter D. Hoff
We introduce a simple and extendable coevolution model for the analysis of longitudinal network and nodal attribute data. The model features parameters that describe three phenomen…
