Dr. Xichao Zhang is currently an Assistant Professor at Waseda University, Japan. He is a member of Prof. Masahito Mochizuki’s Theoretical Group and works jointly with Dr. Xiuzhen Yu’s Electronic States Microscopy Research Team at RIKEN. He received his Ph.D. from Shinshu University in 2018, and was a JSPS Postdoctoral Fellow at Shinshu University (2020-2022). He also worked at the Chinese University of Hong Kong, Shenzhen (2016-2020) and the University of Hong Kong (2014-2016). In 2019, he was awarded the Presidential Postdoctoral Fellowship from the Chinese University of Hong Kong, Shenzhen, and he was elected to be an IEEE Senior Member in 2024.
Dr. Zhang’s research interests broadly encompass spintronics, magnetism, and mesoscopic physics, with a focus on the theoretical and computational study of spin textures, spin dynamics, and spintronic devices. He has been exploring different species of topological spin textures since 2013, including skyrmions, antiskyrmions, skyrmioniums, bimerons, and bimeroniums. Some specific systems that Dr. Zhang works on include bulk chiral magnets, thin films with interfacial chiral interactions, synthetic antiferromagnetic and ferrimagnetic multilayers, and frustrated spin systems. He has also been investigating functional applications such as logic computing gates and transistor-like devices that use topological spin textures in magnetic nanostructures. Recently, his research particularly focuses on the complex dynamics of topological spin textures interacting with artificially nanostructured surfaces and interfaces. In addition, he works on interdisciplinary topics that put concepts from biological physics, soft matter, and fluid dynamics in contact with important questions in spintronics, such as the complex flow phenomena of particle-like spin textures and the dynamic interactions between chiral spin textures and chiral flower-like structures.
Dr. Zhang has published 40 first and co-first author papers in peer-reviewed academic journals, including Nature Physics/Electronics/Communications, Physical Review Letters/Applied/B, Nano Letters, and Applied Physics Letters. He has also coauthored over 80 peer-reviewed academic papers through collaboration with experimental and theoretical groups around the world. Besides, he has contributed five invited chapters to three international books published by Taylor & Francis Group, Elsevier, and Springer. His Google Scholar citations are above 10,000 with an h-index of 41 (as of April, 2024).
