Wave Function Renormalization at Finite Temperature
We present a derivation of the medium dependent wave function renormalization for a spinor eld in presence of a thermal bath. We show that, as already pointed out in literature, projector operators are not multiplicatively renormalized and the e ect involves a non trivial spinor dependence, which disappears in the zero temperature covariant limit. The results, which di er from what already foun...
متن کاملGauge-Invariant Renormalization Group at Finite Temperature
I describe an application of Wilson Renormalization group to the real time formalism of finite temperature field theory. The approach has two nice features: 1) the RG flow equations describe non-perturbatively the effect of thermal fluctuations only, and, 2) the flow is gauge invariant. I then describe the application of the method to the study of the gluon self-energy in SU(N), and present res...
متن کاملRenormalization Group at finite temperature in Quantum Mechanics
We establish the exact renormalization group equation for the potential of a one quantum particle system at finite and zero temperature. As an example we use it to compute the ground state energy of the anharmonic oscillator. We comment on an improvement of the Feynman Kleinert’s variational method by the renormalization group.
متن کاملInheritance principle and Non-renormalization theorems at finite temperature
We show that in the large N limit, a weakly coupled SU(N) gauge theory with adjoint matter on a class of compact manifolds (like S) satisfies an “inheritance principle” in the low temperature phase. Finite temperature correlation functions of gauge invariant single-trace operators are related to those at zero temperature by summing over images of each operator in the Euclidean time direction. T...
متن کاملRenormalization-group approach to anisotropic superconductors at finite temperature.
A renormalization group (RG) analysis of the superconductive instability of an anisotropic fermionic system is developed at a finite temperature. The method appears a natural generalization of Shankar’s approach to interacting fermions and of Weinberg’s discussion about anisotropic superconductors at T = 0. The need of such an extension is fully justified by the effectiveness of the RG at the c...
