Lattice-Driven Chiral Charge Density Wave State in 1T-TaS
Manoj Singh, Boning Yu, James Huber +5
We use scanning tunneling microscopy to study the domain structure of the nearly-commensurate charge density wave (NC-CDW) state of 1T-TaS. In our sub-angstrom characterization…
Enhancing Scene Text Detectors with Realistic Text Image Synthesis Using Diffusion Models
Ling Fu, Zijie Wu, Yingying Zhu +2
Scene text detection techniques have garnered significant attention due to their wide-ranging applications. However, existing methods have a high demand for training data, and obta…
Origin of a Superlattice Observed in LiMoO by Scanning Tunneling Microscopy
Ling Fu, Aaron M. Kraft, Martha Greenblatt +1
We use scanning tunneling microscopy to study the lithium purple bronze (LiMoO) at room temperature. Our measurements allow us to identify the single-crystal c…
OCRBench v2: An Improved Benchmark for Evaluating Large Multimodal Models on Visual Text Localization and Reasoning
Ling Fu, Zhebin Kuang, Jiajun Song +21
Scoring the Optical Character Recognition (OCR) capabilities of Large Multimodal Models (LMMs) has witnessed growing interest. Existing benchmarks have highlighted the impressive p…
Suppression of Superfluid Density and the Pseudogap State in the Cuprates by Impurities
Unurbat Erdenemunkh, Brian Koopman, Ling Fu +5
We use scanning tunneling microscopy (STM) to study magnetic Fe impurities intentionally doped into the high-temperature superconductor BiSrCaCuO. Our sp…
Dataset and Benchmark for Urdu Natural Scenes Text Detection, Recognition and Visual Question Answering
Hiba Maryam, Ling Fu, Jiajun Song +4
The development of Urdu scene text detection, recognition, and Visual Question Answering (VQA) technologies is crucial for advancing accessibility, information retrieval, and lingu…
