Excess energy fluctuations with applications to deviations from Debye's specific heat
Ralph V. Chamberlin, Sumiyoshi Abe
Measured specific heats often exceed Debye's T^3-law, even in high-purity single crystals. Analogous excess energy fluctuations are found in molecular dynamics (MD) simulations of…
Fokker-Planck approach to non-Gaussian normal diffusion: Hierarchical dynamics for diffusing diffusivity
Sumiyoshi Abe
A theoretical framework is developed for the phenomenon of non-Gaussian normal diffusion that has experimentally been observed in several heterogeneous systems. From the Fokker-Pla…
Tsallis entropy: How unique?
Sumiyoshi Abe
It is shown how, among a class of generalized entropies, the Tsallis entropy can uniquely be identified by the principles of thermodynamics, the concept of stability and the axioma…
General pseudoadditivity of composable entropy prescribed by existence of equilibrium
Sumiyoshi Abe
The concept of composability states that entropy of the total system composed of independent subsystems is a function of entropies of the subsystems. Here, the most general pseudoa…
