Critical exponents from optimised renormalisation group flows
Within the exact renormalisation group, the scaling solutions for O(N) symmetric scalar field theories are studied to leading order in the derivative expansion. The Gaussian fixed point is examined for d > 2 dimensions and arbitrary infrared regularisation. The Wilson-Fisher fixed point in d = 3 is studied using an optimised flow. We compute critical exponents and subleading corrections-to-scal...
متن کاملIsing exponents from the functional renormalisation group
We study the 3d Ising universality class using the functional renormalisation group. With the help of background fields and a derivative expansion up to fourth order we compute the leading index, the subleading symmetric and anti-symmetric corrections to scaling, the anomalous dimension, the scaling solution, and the eigenperturbations at criticality. We also study the cross-correlations of sca...
متن کاملEffective Critical Exponents from Finite Temperature Renormalization Group
Effective critical exponents for the λφ4 scalar field theory are calculated as a function of the renormalization group block size k−1 o and inverse critical temperature βc. Exact renormalization group equations are presented up to first order in the derivative expansion and numerical solutions are obtained with and without polynomial expansion of the blocked potential. For a finite temperature ...
متن کاملHolographic renormalisation group flows and renormalisation from a Wilsonian perspective
From the Wilsonian point of view, renormalisable theories are understood as submanifolds in theory space emanating from a particular fixed point under renormalisation group evolution. We show how this picture precisely applies to their gravity duals. We investigate the Hamilton-Jacobi equation satisfied by the Wilson action and find the corresponding fixed points and their eigendeformations, wh...
متن کاملThe density matrix renormalisation group and critical phenomena
We adapt White’s density matrix renormalisation group (DMRG) to the direct study of critical phenomena. We use the DMRG to generate transformations in the space of coupling constants. We postulate that a study of density matrix eigenvalues leads to a natural identification of renormalised blocks, operators and Hamiltonians. We apply the scheme to the phase transition in the anisotropic spin-1/2...
