Multifractality and its role in anomalous transport in the disordered XXZ spin-chain [PDF]

open access: yes, 2020
The disordered XXZ model is a prototype model of the many-body localization transition (MBL). Despite numerous studies of this model, the available numerical evidence of multifractality of its eigenstates is not very conclusive due severe finite size ...

Multifractal Variation Measures and Multifractal Density Theorems

open access: yesReal Analysis Exchange, 2003
For \(E\subseteq {\mathbf R}^d, q, t\in {\mathbf R} \) and \(\delta >0\), \(\mathcal H_\mu^{q,t}\) and \(\mathcal P_\mu^{q,t}\) denote, respectively, the multifractal Hausdorff measure and multifractal packing measure introduced by Olsen and Peyrière.

Pre-freezing of multifractal exponents in Random Energy Models with logarithmically correlated potential [PDF]

open access: yes, 2009
Boltzmann-Gibbs measures generated by logarithmically correlated random potentials are multifractal. We investigate the abrupt change ("pre-freezing") of multifractality exponents extracted from the averaged moments of the measure - the so-called inverse

Two scenarios for quantum multifractality breakdown [PDF]

open access: yes, 2014
We expose two scenarios for the breakdown of quantum multifractality under the effect of perturbations. In the first scenario, multifractality survives below a certain scale of the quantum fluctuations.

Multifractal analysis of stress time series during ultrathin lubricant film melting [PDF]

open access: yes, 2010
Melting of an ultrathin lubricant film confined between two atomically flat surfaces is we studied using the rheological model for viscoelastic matter approximation. Phase diagram with domains, corresponding to sliding, dry, and two types of $stick-slip$

Multifractal Analysis of Charged Particle Multiplicity Distribution in the Framework of Renyi Entropy

open access: yesAdvances in High Energy Physics, 2018
A study of multifractality and multifractal specific heat has been carried out for the produced shower particles in nuclear emulsion detector for 16O-AgBr, 28Si-AgBr, and 32S-AgBr interactions at 4.5AGeV/c in the framework of Renyi entropy.

Multifractal detrended fluctuation analysis of nonstationary time series [PDF]

open access: yes, 2002
We develop a method for the multifractal characterization of nonstationary time series, which is based on a generalization of the detrended fluctuation analysis (DFA).

Decomposing Multifractal Crossovers [PDF]

open access: yesFrontiers in Physiology, 2017
Physiological processes-such as, the brain's resting-state electrical activity or hemodynamic fluctuations-exhibit scale-free temporal structuring. However, impacts common in biological systems such as, noise, multiple signal generators, or filtering by transport function, result in multimodal scaling that cannot be reliably assessed by standard ...
