متن کاملExact renormalization group study of fermionic theories
The exact renormalization group approach (ERG) is developed for the case of pure fermionic theories by deriving a Grassmann version of the ERG equation and applying it to the study of fixed point solutions and critical exponents of the two-dimensional chiral Gross-Neveu model. An approximation based on the derivative expansion and a further truncation in the number of fields is used. Two soluti...
متن کاملHolographic Renormalization Group and Fermionic Boundary Data
We discuss Holographic Renormalization Group equations in the presence of fermions and form fields in the bulk. The existence of a holographically dual quantum field theory for a given bulk gravity theory imposes consistency conditions on the ranks of the form fields, the fermion form field couplings, and leads to a novel Ward identity.
متن کاملFermionic Functional Integrals and the Renormalization Group
The Renormalization Group is the name given to a technique for analyzing the qualitative behaviour of a class of physical systems by iterating a map on the vector space of interactions for the class. In a typical non-rigorous application of this technique one assumes, based on one’s physical intuition, that only a certain finite dimensional subspace (usually of dimension three or less) is impor...
متن کاملRenormalization-group Calculation of Color-Coulomb Potential
We report here on the application of the perturbative renormalization-group to the Coulomb gauge in QCD. We use it to determine the high-momentum asymptotic form of the instantaneous color-Coulomb potential V (~k) and of the vacuum polarization P (~k, k4). These quantities are renormalization-group invariants, in the sense that they are independent of the renormalization scheme. A scheme-indepe...
