Professor Ryotaro Arita and Professor Satoru Nakatsuji Selected for Highly Cited Researchers 2025

Professor Ryotaro Arita, Professor Satoru Nakatsuji

Fifteen researchers from the University have been named to the 2025 Highly Cited Researchers list announced by Clarivate, a global academic information services company. Among them are three faculty members from our Graduate School of Science, including Professor Ryotaro Arita and Professor Satoru Nakatsuji of the Department of Physics.

Since 2014, Clarivate has annually recognized outstanding researchers worldwide as Highly Cited Researchers. This designation honors researchers who have published multiple “Highly Cited Papers”—papers that rank in the top 1% by citations in their respective fields and publication years—and whose work has had a significant influence on subsequent research. In the 2025 list, a total of 6,868 researchers from 60 countries and regions were selected, representing approximately 0.1% of researchers worldwide.

Professors Arita and Nakatsuji have coauthored numerous papers and have continued to produce outstanding achievements in the field of condensed matter physics, particularly in quantum materials related to topological properties. Professor Arita has made significant contributions through first-principles theoretical calculations, providing interpretations of experimental results and offering valuable insights to experimental researchers. His work includes numerous achievements such as the discovery of novel physical properties arising from complex spin structures and theoretical predictions of new high-temperature superconducting materials based on precise theoretical modeling of superconducting transition temperatures.

Professor Nakatsuji, utilizing advanced materials synthesis and state-of-the-art physical property measurement techniques, has discovered a wide range of novel thermomagnetic properties, strong correlation phenomena, and unconventional superconductivity in materials such as magnetic multipoles and Dirac and Weyl semimetals with topological electronic structures. He is also actively engaged in applying these findings to the field of spintronics.

Research on materials with topological electronic states, which has attracted increasing attention over the past two decades, has generated a major wave that significantly expands conventional concepts in condensed matter physics. Including efforts toward practical device applications, Professors Arita and Nakatsuji continue to play leading roles in driving this rapidly evolving field forward.
