Non-Debye relaxations: The characteristic exponent in the excess wings model

  title={Non-Debye relaxations: The characteristic exponent in the excess wings model},
  author={K. G'orska and A. Horzela and Tibor K. Pog'any},
The characteristic (Laplace or Lévy) exponents uniquely characterize infinitely divisible probability distributions. Although of purely mathematical origin they appear to be uniquely associated with the memory functions present in evolution equations which govern the course of such physical phenomena like non-Debye relaxations or anomalous diffusion. Commonly accepted procedure to mimic memory effects is to make basic equations time smeared, i.e., nonlocal in time. This is modeled either… Expand

Non-Debye relaxations: Smeared time evolution, memory effects, and the Laplace exponents
This work links memory functions with the Laplace (characteristic) exponents of infinitely divisible probability distributions and shows how to relate the latter with experimentally measurable spectral functions characterizing relaxation in the frequency domain, to incorporate phenomenological knowledge into the evolution laws.

Anomalous diffusion approach to non-exponential relaxation in complex physical systems
A direct (one-to-one) relationship between the method of random relaxation rates and the anomalous diffusion approach based on subordination of random processes that are applied for the theory of relaxation phenomena is discovered. Expand
Fox function representation of non-debye relaxation processes
Applying the Liouville-Riemann fractional calculus, we derive and solve a fractional operator relaxation equation. We demonstrate how the exponentΒ of the asymptotic power law decay ∼t−β relates toExpand
The Volterra type equations related to the non-Debye relaxation
Results are shown to be equivalent to those obtained using the stochastic approach to relaxation phenomena merged with integral equations involving kernels given by the Prabhakar functions with the positive upper parameter. Expand
Anomalous relaxation model based on the fractional derivative with a Prabhakar-like kernel
Most disordered dielectrics especially solid dielectrics show non-Debye laws, and many empirical approximation models are proposed to describe these anomalous relaxation processes. FractionalExpand

This analysis is a formulation in terms of coupled Langevin equations which allows in a natural way for the inclusion of external force fields and finds that this result is independent of the presence of weak quenched disorder. Expand
Stochastic tools hidden behind the empirical dielectric relaxation laws.
The paper is devoted to recent advances in stochastic modeling of anomalous kinetic processes observed in dielectric materials which are prominent examples of disordered (complex) systems.Expand
Rheological implications of completely monotone fading memory
In the constitutive equation modeling of a (linear) viscoelastic material, the “fading memory” of the relaxation modulus G(t) is a fundamental concept that dates back to Boltzmann [Ann. Phys. Chem.Expand
