Measures of critical exponents in the four-dimensional site percolation [PDF]

, 1997
Using finite-size scaling methods we measure the thermal and magnetic exponents of the site percolation in four dimensions, obtaining a value for the anomalous dimension very different from the results found in the literature.

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

Entropy, 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 ...

Crossover of critical behavior and magnetocaloric effect in FePd2Te2 with one-dimensional Fe chains [PDF]

APL Materials
Recently, a two-dimensional ferromagnet FePd2Te2 exhibiting easy-plane anisotropy with a quasi-one-dimensional spin system has been discovered. We report the magnetic critical behavior and magnetocaloric effect of FePd2Te2 single crystals with magnetic ...

Thermodynamic Derivation of Scaling at the Liquid–Vapor Critical Point

Entropy, 2021
With the use of thermodynamics and general equilibrium conditions only, we study the entropy of a fluid in the vicinity of the critical point of the liquid–vapor phase transition.

Exponent-critical groups

Journal of Group Theory
Abstract We define and investigate the property of being “exponent-critical” for a finite group. A finite group is said to be exponent-critical if its exponent is not the least common multiple of the exponents of its proper non-abelian subgroups. We explore properties of exponent-critical groups and give a characterization of such groups.

Investigation of critical slowing down in a bistable S-SEED [PDF]

, 2003
A simulation of S-SEED switching based upon experimental data is developed that includes the effect of critical slowing down. The simulation's accuracy is demonstrated by close agreement with the results from experimental S-SEED switching. The simulation

The Critical Exponent of Nuclear Fragmentation

Acta Physica Hungarica A) Heavy Ion Physics, 2003
Nuclei colliding at energies in the MeV’s break into fragments in a process that resembles a liquid-to-gas phase transition of the excited nuclear matter. If this is the case, phase changes occurring near the critical point should yield a “droplet” mass distribution of the form ≈A −T, with T (a critical exponent universal to ...

The Critical Exponent is Computable for Automatic Sequences [PDF]

Electronic Proceedings in Theoretical Computer Science, 2011
The critical exponent of an infinite word is defined to be the supremum of the exponent of each of its factors. For k-automatic sequences, we show that this critical exponent is always either a rational number or infinite, and its value is computable. Our results also apply to variants of the critical exponent, such as the initial critical exponent of ...
