Kavli Affiliate: Michael Crommie | First 5 Authors: Jingxu Xie, Zuocheng Zhang, Haodong Zhang, Vikram Nagarajan, Wenyu Zhao | Summary: Advanced microelectronics in the future may require semiconducting channel materials beyond silicon. Two-dimensional (2D) semiconductors, characterized by their atomically thin thickness, hold immense promise for high-performance electronic devices at the nanometer scale with lower heat […]
Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Antonios M. Alvertis, Jonah B. Haber, Zhenglu Li, Christopher J. N. Coveney, Steven G. Louie | Summary: The properties of excitons, or correlated electron-hole pairs, are of paramount importance to optoelectronic applications of materials. A central component of exciton physics is the electron-hole interaction, which is […]
Kavli Affiliate: Feng Wang | First 5 Authors: Ruishi Qi, Qize Li, Zuocheng Zhang, Sudi Chen, Jingxu Xie | Summary: The combination of repulsive and attractive Coulomb interactions in a quantum electron(e)-hole(h) fluid can give rise to novel correlated phases of multiparticle charge complexes such as excitons, trions and biexcitons. Here we report the first […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Ruihan Xu, Ming Sun, Xiang Zhang, , | Summary: For the reduced two-dimensional Belousov-Zhabotinsky slow-fast differential system, the known results are the existence of one limit cycle and its stability for particular values of the parameters. Here, we characterize all dynamics of this system except one degenerate […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Jieru Mei, Alan Yuille, , | Summary: Recent advances in contrastive language-image pretraining (CLIP) have demonstrated strong capabilities in zero-shot classification by aligning visual representations with target text embeddings in an image level. However, in dense prediction tasks, CLIP often struggles to localize visual features […]
Kavli Affiliate: Ting Xu | First 5 Authors: Qiangbo Zhang, Peicheng Lin, Chang Wang, Yang Zhang, Zeqing Yu | Summary: As the realm of spectral imaging applications extends its reach into the domains of mobile technology and augmented reality, the demands for compact yet high-fidelity systems become increasingly pronounced. Conventional methodologies, exemplified by coded aperture […]
Kavli Affiliate: Feng Wang | First 5 Authors: Yiwen Chen, Zilong Chen, Chi Zhang, Feng Wang, Xiaofeng Yang | Summary: 3D editing plays a crucial role in many areas such as gaming and virtual reality. Traditional 3D editing methods, which rely on representations like meshes and point clouds, often fall short in realistically depicting complex […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qiao Wang, , , | Summary: We consider the problem of spectral clustering under group fairness constraints, where samples from each sensitive group are approximately proportionally represented in each cluster. Traditional fair spectral clustering (FSC) methods consist of two consecutive stages, i.e., performing fair spectral […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Chen Ji, Xiang Zhang, Lucas Platter, , | Summary: Precision spectroscopy of hyperfine splitting (HFS) is a crucial tool for investigating the structure of nuclei and testing quantum electrodynamics (QED). However, accurate theoretical predictions are hindered by two-photon exchange (TPE) effects. We propose a novel formalism that […]
