Beyond the Isotropic Lifshitz Endpoint
Tom T. S. Chang
The puzzle of the disappearance of isotropic Lifshitz points in condensed matter physics is explained from the point of view of the Wilsonian renormalization group. In analogy to t…
Complexity Induced Sporadic Localized Multifractal Antiscreening in Gravitational Evolution at Large Scales
Tom T. S. Chang
It has been suggested that antiscreening effects due to the running of the gravitational constant G might provide a partial solution to the dark matter mystery. It has also been hy…
Complexity Phenomena and ROMA of the Magnetospheric Cusp, Hydrodynamic Turbulence, and the Cosmic Web
Tom Chang, Cheng-chin Wu, Marius Echim +4
Dynamic Complexity is a phenomenon exhibited by a nonlinearly interacting system within which multitudes of different sizes of large scale coherent structures emerge, resulting in…
ROMA (Rank-Ordered Multifractal Analysis) for intermittent fluctuations with global crossover behavior
Sunny W. Y. Tam, Tom Chang, Paul M. Kintner +1
Rank-Ordered Multifractal Analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one parameter scaling of monofractals, has the cap…
Rank-ordered Multifractal Spectrum for Intermittent Fluctuations
Tom Chang, Cheng-chin Wu
We describe a new method that is both physically explicable and quantitatively accurate in describing the multifractal characteristics of intermittent events based on groupings of…
Dynamical Complexity, Intermittent Turbulence, Coarse-Grained Dissipation, Criticality and Multifractal Processes
Tom Chang, Cheng-chin Wu
The ideas of dynamical complexity induced intermittent turbulence by sporadic localized interactions of coherent structures are discussed. In particular, we address the phenomenon…
