报告摘要:
In this talk I will first review briefly the concept of Landau-Fermi liquid, the instability of the Landau-Fermi liquid, and then turn to the strongly correlated systems where there may be competing instabilities. Next, I introduce the idea of functional renormalization group, and show how it could be applied to treat the competing instabilities of the correlated manybody system reliably on equal footing, by, e.g., the singular-mode expansion of the 4-point interaction vertices, a truncation scheme which we call the singular-mode functional renormalization group (SM-FRG). I then show some interesting states of matter, some of them topological in nature, obtained by SM-FRG in some particular systems of correlated electrons.
