Analytic Expressions for Debye Functions and the Heat Capacity of a Solid

open access: yesMathematics, 2022
Analytic expressions for the N-dimensional Debye function are obtained by the method of brackets. The new expressions are suitable for the study of heat capacity of solids and the analysis of the asymptotic behavior of this function, both in the high and

Nonequilibrium heat capacity [PDF]

open access: yesPhysical Review E, 2013
Development of steady state thermodynamics and statistical mechanics depends crucially on our ability to develop notions of equilibrium thermodynamics for nonequilibrium steady states (NESS). The present paper considers the development of heat capacity.

Thermal properties of representative soils of the Czech Republic

open access: yesSoil and Water Research, 2013
Knowledge of soil thermal properties is essential when assessing heat transport in soils. Thermal regime of soils is associated with many other soil processes (water evaporation and diffusion, plant transpiration, contaminants behaviour etc.).

Markovian heat sources with the smallest heat capacity

open access: yesNew Journal of Physics, 2018
Thermal Markovian dynamics is typically obtained by coupling a system to a sufficiently hot bath with a large heat capacity. Here we present a scheme for inducing Markovian dynamics using an arbitrarily small and cold heat bath.
