Topological corner states of two-dimensional (2D) higher-order topological insulators (HOTIs) not only serve as a unique signature of higher-order topology, but also possess tremendous potentials in probing, confining, and manipulating par…

Unveiling non-Hermitian band structures with non-Bloch supercells Open

Jiaxin Zhong, Jing Lin, Jing Lu · 2025

Real-valued band structures are foundational to analyzing periodic systems within the Hermitian description and have been experimentally well-established over recent decades. In contrast, non-Hermitian systems exhibit complex band structur…

An end-to-end generalizable deep learning framework to comprehensively analyze transcriptional regulation Open

Zhong Wang, Charles G. Danko, Zhaoxi Zhang, Xiaoya Fan, Jiaxin Zhong , et al. · 2025

Genome annotation currently requires performing dozens of molecular assays in hundreds of cell and tissue samples, an expensive endeavor which is impractical to replicate across all species and conditions of interest. Here, we introduce Bi…

Generating Localized Audible Zones Using a Single-Channel Parametric Loudspeaker Open

Tao Zhuang, Shaoping Li, Feng Niu, Jiaxin Zhong, Jing Lü · 2025

Advanced sound zone control (SZC) techniques typically rely on massive multi-channel loudspeaker arrays to create high-contrast personal sound zones, making single-loudspeaker SZC seem impossible. In this Letter, we challenge this paradigm…
