Nonadiabatic approach to dimerization gap and optical absorption coefficient of the Su-Schrieffer-Heeger model
Qin Wang, Hong Chen, Hang Zheng
An analytical nonadiabatic approach has been developed to study the dimerization gap and the optical absorption coefficient of the Su-Schrieffer-Heeger model where the electrons in…
SciXGen: A Scientific Paper Dataset for Context-Aware Text Generation
Hong Chen, Hiroya Takamura, Hideki Nakayama
Generating texts in scientific papers requires not only capturing the content contained within the given input but also frequently acquiring the external information called \textit…
Modal Regression based Atomic Representation for Robust Face Recognition
Yulong Wang, Yuan Yan Tang, Luoqing Li +1
Representation based classification (RC) methods such as sparse RC (SRC) have shown great potential in face recognition in recent years. Most previous RC methods are based on the c…
Intersecting topological nodal ring and nodal wall states in superhard superconductor FeB4
Feng Zhou, Ying Liu, Jianhua Wang +4
Novel materials with both topological nontrivial states and superconductivity have attracted considerable attention in recent years. Single-crystal FeB4 was recently synthesized an…
Ferrimagnetic-like surface resonance from hybrid metamaterial slab
Zeyong Wei, Hongqiang Li, Chao Wu +4
We show that a hybrid metamaterial slab comprising of an one-dimensional array of two different types of cavities exhibits ferrimagnetic-like surface resonances which can be used t…
Deconstructing Pre-training: Knowledge Attribution Analysis in MoE and Dense Models
Bo Wang, Junzhuo Li, Hong Chen +3
Mixture-of-Experts (MoE) architectures decouple model capacity from per-token computation, enabling scaling beyond the computational limits imposed by dense scaling laws. Yet how M…
