The non-Debye decay length of ionic solutions (κ) is analyzed combining the dressed ion theory route with a new version of the modified mean spherical approximation (MMSA) [Varela et al., J. Chem. Phys. 109, 1930 (1998)]. Seeking formal consistency, the MMSA short-range direct correlation...

Microcanonical equations for some of the most usual thermodynamic properties of a system, suitable for molecular dynamics simulations, are derived from the Tsallis entropy functional using both the usual definition of temperature as a derivative of entropy and a modified physical one introduced...
