Current Interest

Lectures and publications

I am making some lecture videos public. Please see the ist of my online lectures.
The lecture series in 2021 on "Symmetry-protected topological (SPT) phases and topological indices in quantum spin chains" may be useful to some.

For my scientific papers, see my Google Scholar page.

The following is the list of my books in English.

Research Topics (obsolete!)

One of the aims of physics is to elicit "universal" properties from the world we observe (in various manners), and truly "understand" them. I have been mostly interested in various physical problems in which many (or infinitely many) degrees of freedom generate nontrivial physics, and worked on problems from such fields as statistical physics, condensed matter physics, and field theories. I have been trying to prove mathematically rigorous results which are at the same time important and enlightening from physicists' point of view.

Main topics and their detais follow. There is also a list of selected publications.
