◆Research Interests
Quantum many-body theory and Massive Parallel Simulations
As an expert team on the numerical many-body electron theory using Diffusion Monte Carlo technique (CASINO, QMCPack and TurboRVB), we've worked on the topics on the foundation of ab initio methods, such as the origin of the magnetic moments, the Hund rule, electronic correlations and phonons, Casimir-Polder interactions, Exciton-Mott transitions etc. We've published in such journals as JACS(IF=13.858)/Angewande(IF=11.709)/Phys.Rev.Lett.(7.435)/JCTC(5.39)/Sci.Rep.(5.228)/Inorg.Chem.(4.857)/Phys.Rev.B(3.767)/J.Chem.Phys.(3.164)/J.Comput.Chem.(3.84)/Appl.Phys.Lett.(3.794)
