Welcome to Yusuke Iguchi's personal page
Dr. Iguchi received his B.S. in physics at Tokyo University of Science in 2013 and received his Ph.D. in Basic Science from the University of Tokyo in 2018. Since 2018, he has worked at Stanford University with Prof. Kathryn Ann Moler. From 2018-2020, he was JSPS Overseas Fellow in Applied Physics. Since 2020, in addition to conducting his research, he has mentored students and helped to manage the group's operations as a senior research scientist in the Geballe Laboratory for Advanced Materials.
Dr. Iguchi is an experimental physicist in the field of condensed matter physics, with a focus on unconventional superconductors and non-centrosymmetric magnets. His wide-ranging research covers diverse areas, including the exploration of spin dynamics in ferromagnetic insulators and chiral edge currents in topological superconductors. His achievements include the observation of non-reciprocal magnon-propagation in chiral ferromagnets, pioneering electromagnetic control over non-reciprocal microwave propagation in multiferroic materials, uncovering local superconducting states and intrinsic magnetism in candidates for chiral superconductors, the observation of unquantized vortices in multiband superconductors, and the observation of the anomalous superfluid density potentially linked to quantum fluctuations.
Dr. Iguchi received honors and awards, including Overseas
Research Fellowship of JSPS (2018), Journal of Physics Society of Japan Papers
of Editors' Choice (2017), DC2 Research Fellowship of JSPS (2016), and
Outstanding Graduate Student Award from University of Tokyo (2015). In addition,
He founded the Association for Japanese Researchers at Stanford
University. In 2024, he joined UJA and launched the Community Launching Support as the Project Leader.
