Optimal distribution modeling and multifractal analysis of wind speed in the complex terrain of Sichuan Province, China [PDF]

open access: yesScientific Reports
Increasing drought events have threaten electricity supply security in the predominantly hydropower-based Sichuan Province. Wind power has the potential to complement hydropower, yet its complex fluctuations required a systematic assessment. Accordingly,

Are clean energy markets efficient? A multifractal scaling and herding behavior analysis of clean and renewable energy markets before and during the COVID19 pandemic [PDF]

open access: yesHeliyon, 2023
The literature lacks thorough and adequate evidence of the efficiency and herding behavior of clean and renewable energy markets. Therefore, the key objective of this paper is to explore the multifractality and efficiency of six clean energy markets by ...

Quantum logarithmic multifractality

open access: yesPhysical Review Research
Through a combination of rigorous analytical derivations and extensive numerical simulations, this work reports an exotic multifractal behavior, dubbed “logarithmic multifractality,” in effectively infinite-dimensional systems undergoing the Anderson ...

Multifractality without fine-tuning in a Floquet quasiperiodic chain [PDF]

open access: yesSciPost Physics, 2018
Periodically driven, or Floquet, disordered quantum systems have generated many unexpected discoveries of late, such as the anomalous Floquet Anderson insulator and the discrete time crystal.

On Tail Dependence and Multifractality

open access: yesMathematics, 2020
We study whether, and if yes then how, a varying auto-correlation structure in different parts of distributions is reflected in the multifractal properties of a dynamic process.

Research on Efficiency and Multifractality of Gold Market under Major Events

open access: yesFractal and Fractional
(1) Background: As a safe-haven asset, gold attracts a large number of investors during major events. Uncertainties caused by global economic and market conditions lead to increased purchases of gold by investors, which in turn affects the efficiency of ...

Multifractality in critical neural field dynamics

open access: yes
The brain criticality hypothesis has largely only characterized brain dynamics in terms of their self-similarity, although experimental evidence suggests that the brain exhibits significant multifractality. To understand how multifractality may emerge in
