Acoustic experiments confirm topology can persist at gapless critical points
Researchers have confirmed through acoustic experiments that topological properties of matter can persist even at gapless critical points. This finding challenges conventional physics by demonstrating that global topological invariants remain robust despite the absence of a band gap.
Why it matters
This discovery advances the fundamental understanding of topological phases of matter, which are essential for developing stable quantum materials and technologies.

Add to Preferred Sources Credit: Steve A Johnson from Pexels Two studies on critical topology have recently been published in the journal Nature . These studies were led by the teams of Prof. Baile Zhang at Nanyang Technological University, Singapore, and Prof. Jianhua Jiang at the University of Science and Technology of China, respectively. Prof. Xue-Jia Yu from the School of Physics at the Eastern Institute of Technology, Ningbo (EIT), served as a co-corresponding author on both papers and provided key theoretical guidance in the related experimental collaborations.
To understand the significance of this work, we first need to discuss the concept of topology.
