Levels of Complexity in Scale-Invariant Neural Signals
Plamen Ch. Ivanov, Jeffrey M. Hausdorff, S. Havlin +5
Many physical and physiological signals exhibit complex scale-invariant features characterized by scaling and long-range power-law correlations, suggesting a possibly common…
Scaling of star polymers: high order results
V. Schulte-Frohlinde, Yu. Holovatch, C. von Ferber +1
We extend existing renormalization group calculations for the exponents describing scaling of star polymers and polymer networks constituted by chains of different species (the so-…
Relation between Magnitude Series Correlations and Multifractal Spectrum Width
Yosef Ashkenazy, Shlomo Havlin, Plamen Ch. Ivanov +3
We study the correlation properties of long-range correlated time series, , with tunable correlation exponent and built-in multifractal properties. For the cases we investigat…
Critical Exponents from Five-Loop Strong-Coupling phi^4-Theory in 4- epsilon Dimensions
Hagen Kleinert, Verena Schulte-Frohlinde
With the help of strong-coupling theory, we calculate the critical exponents of O(N)-symmetric phi^4-theories in 4- epsilon dimensions up to five loops with an accuracy comparable…
Stability of 3D Cubic Fixed Point in Two-Coupling-Constant ϕ^4-Theory
H. Kleinert, S. Thoms, V. Schulte-Frohlinde
For an anisotropic euclidean -theory with two interactions $[u (\sum_{i=1^M ϕ_i^2)^2+v \sum_{i=1}^M ϕ_i^4]$ the -functions are calculated from five-loop perturbation expans…
Five-loop renormalization group functions of -symmetric -theory and $\ep$-expansions of critical exponents up to $\ep^5$
H. Kleinert, J. Neu, V. Schulte-Frohlinde +2
Motivated by the discovery of errors in six of the 135 diagrams in the published five-loop expansions of the -function and the anomalous dimensions of the -symmetric $ϕ^…
