The collaborative research led by our former Project Assistant Professor, Dr. Takuya Matsuda (current position: assistant professor at Osaka University), is now published in Physical Review Materials. Using time-resolved terahertz Faraday rotation spectroscopy, this work uncovers high-mobility carriers with a surprisingly long lifetime extending to several tens of picoseconds in the non-equilibrium state of Mn3Sn, sharply contrasting its "bad-metal" behavior in equilibrium. This is an important step forward for understanding the role of electronic correlation in influencing the transport properties of Mn3Sn, incentivizing us to think beyond the standard single-particle framework when investigating correlated topological materials.
This work arose from a collaboration with several research teams within the Trans-Scale Quantum Science Institute of the University of Tokyo (Prof. R. Matsunaga, Prof. R. Shimano, and Prof. T. Kondo) and theoretical input from Prof. T. Koretsune at Tohoku University.
