The critical exponent functions [PDF]

open access: yesComptes Rendus. Mathématique, 2022
The critical exponent of a finite or infinite word w over a given alphabet is the supremum of the reals α for which w contains an α-power. We study the maps associating to every real in the unit interval the inverse of the critical exponent of its base-n expansion. We strengthen a combinatorial result by J.D. Currie and N.

Critical behavior of quasi-two-dimensional semiconducting ferromagnet CrGeTe$_3$ [PDF]

open access: yes, 1927
The critical properties of the single-crystalline semiconducting ferromagnet CrGeTe$_3$ were investigated by bulk dc magnetization around the paramagnetic to ferromagnetic phase transition.

Disorder-induced critical exponents near a ferromagnetic quantum critical point in Mn1−xCrxSi [PDF]

open access: yes, 2020
We report the observation of critical behavior in Mn1−xCrxSi (0≤x≤1) close to a T = 0 K quantum critical point, consistent with the Belitz-Kirkpatrick-Vojta (BKV) theory of disordered metallic ferromagnets.

Critical exponents without β-function [PDF]

open access: yesPhysics Letters B, 1999
We point out that the recently developed strong-coupling theory enables us to calculate the three main critical exponents nu, eta, omega, from the knowledge of only the two renormalization constants Z_phi of wave function and Z_m of mass. The renormalization constant of the coupling strength is superfluous, and with it also the beta-function, the ...

Scale-Free Chaos in the 2D Harmonically Confined Vicsek Model

open access: yesEntropy, 2023
Animal motion and flocking are ubiquitous nonequilibrium phenomena that are often studied within active matter. In examples such as insect swarms, macroscopic quantities exhibit power laws with measurable critical exponents and ideas from phase ...

Critical exponents for diluted resistor networks [PDF]

open access: yesPhysical Review E, 1999
An approach by Stephen is used to investigate the critical properties of randomly diluted resistor networks near the percolation threshold by means of renormalized field theory. We reformulate an existing field theory by Harris and Lubensky. By a decomposition of the principal Feynman diagrams we obtain a type of diagrams which again can be interpreted

Critical exponents and where to find them

open access: yesBruno Pini Mathematical Analysis Seminar, 2018
In this expository paper we present a list of different semilinear wave-type problems with time-variable coefficients. The aim of this work is to understand the influence of such coefficients on the critical exponents for polynomial nonlinearities ...
