Theoretical Quantum Physics 

Researchers in theoretical quantum physics division study atoms, molecules, clusters, and solids using quantum mechanics, theoretically. They deal with nonlinear optical processes, multi-photon processes, chemical reaction processes, and dielectric, magnetic and superconducting phenomena. Some of them are members of Center for Computational Sciences of University of Tsukuba.
Hino Lab.

We theoretically study photoinduced phenomena in condensed matters (including semiconductor nanostructures, molecular crystals, and so on), caused by irradiation of strong laser. In particular, we explore novel phenomena resulting from interactions between light and materials, from the aspect of non-equilibrium quantum dynamics.


Koizumi Lab. 

The current focus in our research group is the elucidation of the mechanism of copper oxide high temperature superconductors. We have proposed a new theory of electrical conductivity using a spin Berry phase, which is expected to be operative in them.


Shugo Suzuki Lab. 

We study electronic structures and magnetic/optical properties of materials using fully relativistic full-potential LCAO method.


Tong Lab.

We are investigating the dynamical process of atoms, molecules in the external electrical and/or magnetic fields using large scale numerical simulation. Furthermore, we are searching the possible way to control the atomic, molecular dynamics using the external fields. Specifically, we are developing a numerical method to solve the time-dependent Schrodinger equation to study various dynamical processes, such as the nonlinear process in the atom (or molecule) interacting with the intense pulsed laser or the formation of exotic atom when antiprotons collide with atoms. We are also searching the way to control the atomic or molecular structures using oscillating magnetic fields.
