Yu-Hsuan (Eugene) is a third year Physics PhD student in Professor Joel Moore’s group. Prior to his PhD journey in UC Berkeley, Yu-Hsuan received his BS degree in physics from National Tsing Hua University at Taiwan. He also went through nine years of athletic track training. In his free time, he likes to go to the gym, enjoy classical music, and learn things that are way outside his comfort zone.
Yu-Hsuan’s work focuses on theoretical transport properties of topological materials with magnetic textures. Manipulation and probing of magnetic textures in noncollinear topological antiferromagnets such as Mn3X (X=Sn, Ge,...) are vital for the progress of antiferromagnetic spintronics. He aims to investigate the theory of the chiral Hall effect and spin-orbit torque in Mn3X and develop new experimental techniques to manipulate magnetic textures in such materials. The noncollinearity of magnetic textures in Mn3X adds a high level of complexity to the investigation.
Furthermore, Yu-Hsuan also focuses on developing a general theory of conductivity tensor of an N-spin system. The central issue is to identify a series of order parameters for an N-spin system. It has important application in next - generation memory device since a hierarchy of order parameters provides us a variety of knobs to write-in and read-out an AFM memory device.
