Princeton scientists discover a topological magnet that exhibits exotic quantum effects

Recommendable! Caution: This article is tough reading for lay people (including myself)! This research took 10 years to bring it to fruition! Apparently, Chinese researchers in Beijing made major contributions to this research.


This research paper is full of rather new or unusual scientific terms: Kagome magnets, Chern quantum phases, Chern gapped Dirac fermions, quantum Hall effect, magnetic topological material ...

"The researchers discovered a quantized topological phase in a pristine magnet. Their findings provide insights into a 30-year-old theory of how electrons spontaneously quantize and demonstrate a proof-of-principle method to discover new topological magnets ... Quantum magnets are promising platforms for dissipationless current, high storage capacity and future green technologies. ... “There are hundreds of kagome magnets, and we need both intuition, experience, materials-specific calculations, and intense experimental efforts to eventually find the right material for in-depth exploration. And that took us on a decade-long journey.”"



Princeton scientists discover a topological magnet that exhibits exotic quantum effects – Discovery: Research at Princeton An international team led by researchers at Princeton University has uncovered a new class of magnet that exhibits novel quantum effects that extend to room temperature.
