Title: Functional-renormalization-group aided density functional theory
Time/Date: 13:45-, October 25, 2019
Place: Meeting Room B, Center for Computational Sciences (1F), University of Tsukuba
Abstract: The functional-renormalization-group aided density functional theory (FRG-DFT) is an attempt to microscopically formulate the density functional theory borrowing ideas from the functional renormalization group. This method is expected to become a powerful approach for the fundamental problems of the density functional theory such as the microscopic determination of the energy density functional and the analyses of excited states involving the large-amplitude collective dynamics.
In this talk, I will introduce the FRG-DFT and present our works, which includes the formulation for continuum homogeneous matters [1], the analysis of the ground and excited states of a one-dimensional fermionic matter [1, 2], and the application to the two-dimensional homogeneous electron gas [3]. I may also discuss our recent works on the application to systems with arbitrary spin polarization and superfluidity.
