简历: I am a theoretical/computational condensed matter physicist. I received my Ph. D in physics in 2011 in the University of Tokyo under supervision of Prof. Naoki Kawashima. Then, I became a postdoc in Los Alamos National Laboratory in 2011. After 3 years in the US, I moved back to Japan in 2014 and worked in RIKEN for my second postdoc, until I joined Shanghai Jiao Tong University (SJTU) in Dec. 2018 as a tenure-track associate professor.
Very broadly, I am interested in physics of so-called emergent states of matter in condensed matter systems. Examples of emergent states include quantum spin liquids, exotic magnetic order in frustrated spin systems, multiferroic states, and topological insulators and superconductors. Especially, exploring topological nature of excitations has been an interesting research direction to uncover new physics, such as spinons in quantum spin liquids and edge/surface states in topological matters.
Highlights of my research include a theory of magnetic vortex crystals in quantum magnets, a theory of novel multiferroics, a quantum Monte Carlo study of Z2 spin liquids, a theory of strongly-correlated magnons in a frustrated magnet, and so on (see the selected publication list for details). Quantum Monte Carlo methods are one of my specialties, while I also use analytical methods such as large-N and large-S expansions. In addition, I have collaborations with both theoretical and experimental researchers in University of Tennessee, Oak Ridge National Laboratory, Los Alamos National Laboratory, the University of Tokyo, and, last but not the least, SJTU.
In SJTU, Prof. Xiaoqun Wang, Prof. Mingpu Qin, Prof. Zi Cai, and myself form a loosely-connecting research group sharing the common interest of studying strongly correlated systems by using a variety of numerical methods.
