Renormalization Scheme Dependence
The running couplings such as λ(E) depend not only on the energy scale E but also on the specific rules we use to fix the finite parts of δλ(E) and other counterterms. If we change those rules — collectively known as the renormalization scheme — then for the same energy scale E we would get a slightly different running coupling λ(E) 6= λ(E). The difference is due to quantum corrections which us...

متن کاملOn scheme dependence of gravitational dressing of renormalization group functions
It is shown that for 2D field theories only the first order coefficient of the gravitationally dressed RG β-function is scheme independent. This is valid even for matter theories with one dimensionless coupling, where the first two coefficients of the original β-function are scheme independent.
متن کاملRenormalization-group Theory and Universality along the Lambda Line Of
The present status of the renormalization-group (RG) predictions on the superfluid density ρ s and the specific heat C + and C − near the λ-line of 4 He is briefly reviewed. Particular attention is given to universal amplitude ratios related to these quantities. The goals of a new theory project are presented that involves higher-order calculations of the amplitude functions of ρ s , C + and C ...
متن کاملCluster Functional Renormalization Group
Functional renormalization group (FRG) has become a diverse and powerful tool to derive effective low-energy scattering vertices of interacting many-body systems. Starting from a non-interacting expansion point of the action, the flow of the RG parameter Λ allows to trace the evolution of the effective one-particle and two-particle vertices towards low energies by taking into account the vertex...
