The Wilson-Polchinski Renormalization Group Equation in the Planar Limit
We derive the Wilson-Polchinski RG equation in the planar limit. We explain that the equation necessarily involves also non-planar amplitudes with sphere topology, which represent multi-trace contributions to the effective action. The resulting RG equation turns out to be of the Hamilton-Jacobi type since loop effects manifest themselves through terms which are linear in first order derivatives...
متن کاملLimit Cycles in the Renormalization Group
This paper will review the consequences of having limit cycles in the renormalization group. Characteristics such as discrete symmetry invariance and log periodic behavior of observables are expected in systems that exhibit limit cycles in their renormalization group. Some realizations of limit cycles will be explained. Specifically limit cycles in RG flows will be used to explain the Efimov ef...
متن کاملThe Wilson-Polchinski exact renormalization group equation
The critical exponent η is not well accounted for in the Polchinski exact formulation of the renormalization group (RG). With a particular emphasis laid on the introduction of the critical exponent η, I re-establish (after Golner, hep-th/9801124) the explicit relation between the early Wilson exact RG equation, constructed with the incomplete integration as cutoff procedure, and the formulation...
متن کاملRenormalization group improved BFKL equation ∗
The calculation of next-to-leading log x corrections to the BFKL equation was completed last year [1,2] after several years of theoretical effort. The results, for both anomalous dimension and hard Pomeron, show however signs of instability due to both the size and the (negative) sign of corrections, possibly leading to problems with positivity also [3]. If we write the eigenvalue equation corr...
متن کاملRegularized Quantum Master Equation in the Wilsonian Renormalization Group
Using the Pauli-Villars regularization, we make a perturbative analysis of the quantum master equation (QME), Σ = 0, for the Wilsonian effective action. It is found that the QME for the UV action determines whether exact gauge symmetry is realized along the renormalization group (RG) flow. The basic task of solving the QME can be reduced to compute the Troost-van Niuwenhuizen-Van Proyen jacobia...
