Cutting-decimation Renormalization for Diiusive and Vibrational Dynamics on Fractals

چکیده

Recently, we pointed out that on a class on non exactly decimable frac-tals two diierent parameters are required to describe diiusive and vibra-tional dynamics. This phenomenon we call dynamical dimension splitting is related to the lack of exact decimation invariance for these structures, which turn out to be invariant under a more complex cutting-decimation transform. In this paper we study in details the dynamical dimension splitting on these fractals analyzing the mathematical properties of the cutting-decimation transform. Our results clarify how the splitting arises from the cutting transform and show that the dynamical dimension de-generation is a very peculiar consequence of exact decimability.

Instability of Renormalization-Group Pathologies under decimation

We investigate the stability and instability of pathologies of renormalization group transformations for lattice spin systems under decimation. In particular we show that, even if the original renormalization group transformation gives rise to a non Gibbsian measure, Gibbsiannes may be restored by applying an extra decimation trasformation. This fact is illustrated in details for the block spin...

Data Compression of Cutting Plane

We propose an efficient algorithm for compressing cutting plane of three dimensional Computational Fluid Dynamics (CFD) data set. Observing the cutting planes of large 3D CFD data set is an important method for examination of simulation result, and efficient compression algorithm of these cutting planes is important for good performance of visualization when the simulation is running in a remot...

Renormalization-group Investigation of the S = 1 Random Antiferromagnetic Heisenberg Chain

We introduce variants of the Ma-Dasgupta renormalization-group (RG) approach for random quantum spin chains, in which the energy-scale is reduced by decimation built on either perturbative or non-perturbative principles. In one non-perturbative version of the method, we require the exact invariance of the lowest gaps, while in a second class of perturbative Ma-Dasgupta techniques, different dec...

Real Space Renormalization Group for Langevin Dynamics in Absence of Translational Invariance

A novel exact dynamical real space renormalization group for a Langevin equation derivable from a Euclidean Gaussian action is presented. It is demonstrated rigorously that an algebraic temporal law holds for the Green function on arbitrary structures of infinite extent. In the case of fractals it is shown on specific examples that two different fixed points are found at variance with periodic ...
