Point-free topology provides an alternative framework to classical topology by focusing on the lattice of open sets rather than on the individual points of a space. At its core, this approach ...

Dr. Hu drew inspiration from studies of 1D NHSE. In 1D, NHSE arises from point gaps, where energy spectra under periodic boundary conditions form loops in the complex plane.

There’s no Nobel Prize in mathematics, but math undergirds much high-level science. The 2016 Nobel in Physics rewards work in topology, a branch of math with multiple real world applications.

Topology in higher dimensions. At this point, it may seem like there is no reason to consider spaces that have dimensions larger than four, ...

A study, published in the journal Science Bulletin and led by Dr. Haiping Hu from the Institute of Physics, Chinese Academy of Sciences (IOP, CAS), explores the non-Hermitian skin effect (NHSE ...
