Abstract
Conformable derivatives provide a mathematically tractable approach to modeling anomalous relaxation and scaling in complex systems, yet their physical origin remains poorly understood. We address this gap by deriving conformable relaxation dynamics from first principles. Our approach is based on a spatially-resolved Ginzburg–Landau model incorporating quenched disorder and temperature-dependent kinetic coefficients. Applying statistical averaging and transport-theoretic arguments, we demonstrate that spatial heterogeneity and energy barrier distributions generate power-law memory kernels of the form . In the adiabatic limit, these memory effects reduce to a local conformable evolution law . We show that the deformation parameter is directly linked to measurable quantities such as transport coefficients, susceptibility, energy barrier distributions, and the underlying disorder exponent. Furthermore, is related to Tsallis nonextensive entropy via the relation . These results establish a microscopic foundation for conformable dynamics in disordered media, provide a physical interpretation of the deformation parameter, ensure thermodynamic consistency with entropy production, and yield experimentally testable predictions. Observable consequences include specific relaxation spectra and susceptibility decay patterns. Overall, the framework unifies memory effects, nonextensive thermodynamics, and critical phenomena within a coherent and physically grounded description.

Physica A: Statistical Mechanics and its Applications
Recognized by the European Physical Society
Physica A publishes research in the field of statistical mechanics and its applications.
Statistical mechanics sets out to explain the behaviour of macroscopic systems by studying the statistical properties of their microscopic constituents.
Applications of the techniques of statistical mechanics are widespread, and include: applications to physical systems such as solids, liquids and gases; applications to chemical and biological systems (colloids, interfaces, complex fluids, polymers and biopolymers, cell physics); and other interdisciplinary applications to for instance biological, economical and sociological systems.
