RESEARCH

I have focused on magnetism and ferroelectricity in multiferroic materials, especially transition-metal oxides. In this project, I plan to perform first-principles calculations in order to understand the microscopic mechanisms of topological material properties through the bandstructure. It is also planned to search new topological materials by using an evolutionary algorithm.
