A majority-rule model : real-space renormalization-group solution and finite size scaling
2014 Through a simple majority-rule a statistical geometrical d-dimensional model (d can even be a fractal dimensionality) is formulated which presents a continuous phase transition as a function of a certain independent occupancy probability p. Both critical point pc and « correlation length » exponent 03BD are exactly calculated through real-space renormalization-group (with linear scaling fa...
متن کاملTime-Dependent Real-Space Renormalization Group Method
In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...
متن کاملRenormalization-group theory for finite-size scaling in extreme statistics.
We present a renormalization-group (RG) approach to explain universal features of extreme statistics applied here to independent identically distributed variables. The outlines of the theory have been described in a previous paper, the main result being that finite-size shape corrections to the limit distribution can be obtained from a linearization of the RG transformation near a fixed point, ...
متن کاملFinite-Size Scaling from the non-perturbative Renormalization Group
The phase diagram of QCD at finite temperature and density and the existence of a critical point are currently very actively researched topics. Although tremendous progress has been made, in the case of two light quark flavors even the order of the phase transition at zero density is still under discussion. Finite-size scaling is a powerful method for the analysis of phase transitions in lattic...
