Welcome to My Website! :)

I'm Kazuyuki SEKIZAWA, a Nuclear Physicist, working at Institute of Science Tokyo in Japan, as an Assocoate Professor. I'm working on Nuclear Theory and interested in quantum many-body dynamics of various kinds: e.g. collisions of atomic nuclei, superfluid vortices inside neutron stars, ultracold atomic gasses, and so forth.

This is my personal website. For the information about our Nuclear Theory Group at Science Tokyo, see:
