Research Abstract

In this study, we have mainly performed three topics of research as follows:
(1)Dynamical CDFT: On the basis of the Hamiltonian which explicitly includes the internal electromagnetic field, we developed the dynamical CDFT. Concerning the exchange-correlation energy functional that is contained in the resultant single-particle equation of the dynamical CDFT, we also proposed adiabatic approximation called AVEA. (2)Tight-binding method for solids immersed in a magnetic field: We developed the relativistic tight-binding method for solids immersed in an external magnetic field. We also applied this method to the crystalline silicon immersed in an external magnetic field. (3)Static CDFT for superconductors immersed in a magnetic field: We developed the static CDFT for superconductors immersed in a magnetic field. This theory can reproduce the superconducting order parameter which has various spin symmetry and dependence of the center of mass coordinate.
