For the comprehension of this phenomenon, self-consistent microscopic calculations combined with the band theory is strongly desired. This trend just started from 2005[1][2], and there is still a lot of room for progress and improvement.
In our research, we realized the Time-Dependent Density Functional Theory (TDDFT) extended for superfluid systems (TDSLDA) combined with the band theory, and calculations were performed for 1 dimensional (slab) crystalline structures, imposing β equilibrium condition[3]. In this presentation, we will first show the scheme and formulation of our calculations. We then discuss the results obtained for the slab phases and present possible progress towards further applications.
