Shankar renormalization group
Webbis included. 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. WebbThe contractor renormalization group (CORE) method, a new approach to solving Hamiltonian lattice systems, is introduced. The method combines contraction and variational techniques with the real-space renormalization group approach. It applies to lattice systems of infinite extent and is ideal for studying phase structure and critical …

Webb3 apr. 2024 · Leonhard et al. analyzed all orthorhombic groups and concluded that for this group there are two such planes, defined by the conditions k x = π/a and k y = π/b, respectively, and two lines, Z–T and Z–U. Degenerate planes generate nodal lines on the Fermi surface, which in CoTe 2 form two closed loops (shown in Figure 1b as red loops) … Webb7 juli 1993 · Renormalization Group Approach to Interacting Fermions.
