Fermionic renormalization group method based on the smooth Feshbach map
with d ∈ N and s a non-negative half integer, and denote the creation and annihilation operators by b∗(k), b(k), which formally obey the canonical anticommutation relations, {b(k), b∗(k̃)} = δl,l̃δ(k− k̃), {b(k), b(k̃)} = {b ∗(k), b∗(k̃)} = 0, k = (k, l), k = (k̃, l̃) ∈ M ≡ R × L. If the Hamiltonian HS has a discrete eigenvalue E the free Hamiltonian H0 of the total system has the same eigenvalue E, w...
متن کاملOperator renormalization group.
We introduce a novel operator renormalization group method. This is a new and more powerful variant of the t-expansion combining that method with the real space renormalization group approach. The aim is to extract infinite volume. physics at t + oo from calculations of only a few powers of t. Good results are obtained for the 1 + 1 dimensional Iking model. The method readily generalizes to hig...
متن کاملOperator-theoretic renormalization group and aspects of the infrared problem in non-relativistic QED
One of the key difficulties in the study of non-relativistic QED is the appearance of infrared singularities in the computation of many fundamentally important quantities, such as scattering amplitudes (if computed naively), which originate from the fact that the photon has no mass. The link between zero photon mass, and the infrared pathologies can be explained as follows. By Planck’s law, the...
متن کاملPhenomenological Renormalization Group Methods
Some renormalization group approaches have been proposed during the last few years which are close in spirit to the Nightingale phenomenological procedure. In essence, by exploiting the finite size scaling hypothesis, the approximate critical behavior of the model on infinite lattice is obtained through the exact computation of some thermal quantities of the model on finite clusters. In this wo...
متن کاملOperator Product Expansion , Renormalization Group and Weak Decays ∗ Andrzej
A non-technical description of the Operator Product Expansion and Renormalization Group techniques as applied to weak decays of mesons is presented. We use this opportunity to summarize briefly the present status of the next-to-leading QCD corrections to weak decays and their implications for the unitarity triangle, the ratio ε/ε, the radiative decay B → Xsγ, and the rare decays K+ → π+νν̄ and K...
