I delivered my lecture, "Multicomponent Superconductivity and Flux Quantization: Insights from Local Magnetic Imaging," in Frontiers of Condensed Matter Physics (FCMP) Columbia 2026 Spring Online Lectures, Columbia University, organized by Prof. Yasutomo J. Uemura.
Welcome to Yusuke Iguchi's personal page
Yusuke Iguchi is an experimental condensed matter physicist specializing in superconductivity, magnetism, and quantum materials. He received his B.S. in physics from Tokyo University of Science in 2013 and his Ph.D. in Basic Science from the University of Tokyo in 2018. From 2018 to 2026, he conducted research in the laboratory of Prof. Kathryn Ann Moler at Stanford University, where he served as a Senior Research Scientist and contributed to the development and operation of advanced scanning SQUID microscopy and cryogenic measurement platform.
His research focuses on the local magnetic imaging of emergent quantum phenomena, including unconventional superconductivity, multicomponent superconductivity, magnetic quantum criticality, and topological magnetic states. His work has led to several notable discoveries, including the observation of unquantized vortices in multiband superconductors, local magnetic signatures of candidate chiral superconductors, anomalous superfluid density associated with quantum fluctuations, and nonreciprocal spin wave propagation in chiral magnets.
Dr. Iguchi has authored more than 20 peer-reviewed publications, including papers in Science, Physical Review Letters, and other leading journals in condensed matter physics. His research has been recognized through several awards, including the UJA Outstanding Paper Award (2024), the JSPS Overseas Research Fellowship (2018), the JSPS DC2 Fellowship (2016), and the Outstanding Graduate Student Award from the University of Tokyo (2015). In addition, his work has been selected multiple times as Editors' Suggestions and Editors' Picks in leading physics journals, including Physical Review Letters, Physical Review B, Physical Review Materials, Applied Physics Letters, and the Journal of the Physical Society of Japan.
Beyond his research, he actively supports the Japanese scientific community in the United States. He co-founded the Association for Japanese Researchers at Stanford University (JASS) and currently serves as a Co-Director of UJAW, a U.S.-based nonprofit organization that supports Japanese researchers and scholars throughout the United States.
