Shankar renormalization group
Webb21 maj 2024 · The renormalization group is (mainly) a way to effectively deal with theories where there is some large separation between scales. Often the UV (high energy) degrees of freedom are irrelevant for low energy physics and an effective description can be found by imposing that that the system is invariant under coarse-graining. Webbincluded. The renormalization group is developed and applied to critical phenomena, Fermi liquid theory and the renormalization of field theories. Next, the book explores bosonization and its applications to one-dimensional fermionic systems and the correlation functions of homogeneous and random-bond Ising models.

Degenerate planes generate nodal lines on the Fermi surface, which in CoTe 2 form two closed loops (shown in Figure 1b as red loops) … WebbP.O.
