Welcome

Since the perfomance of computers have drastically incresed recently, the numerical simulations of dynamics of fluxoid based on TDGL (Time Depended Ginzburg Landau) equation has been frequently reported. This kind of numerical simulation is as important as experimental study. Therefore, it is desired to clarify the availability of TDGL. In addition, the control of the nano structure inside the superconductor such as artifitial pinning centers is one of the hot topics. Hence, the numerical calculation of pinning force from the interaction between nano size pinning center and flux lines becomes important.

For this pourpose, we initiate the new research group in JSAP (Japanese Society of Applied Physics). The aim of our group is opening the discussion group for simulation of flux line-dynamics and complicated phenomenon of superconductor to cotribute to the application of research works of superconductors.

If you have intereted in our group, please contact to us.
