Non-extensive thermostatistics approach to metal melting entropy

Abstract: A generalized Mott relation of metal melting entropy is derived by means of non-extensive solid and liquid quantum entropy that we calculate from grand partition functions of localized ordered quantum solid and of disordered quantum Boltzmann liquid. For each of the 18 elements considered the entropic parameter q m , depending on particle correlations, is deduced such that a better agreement is obtained between calculated non-extensive metal melting entropy and available experimental data. The non-extensive en… Show more

“…We propose that negative entropy, in particular the negative contribution to entropy arising from two-and many-body correlations, has a great effect on the rates of nuclear fusions. The role of generalized statistics and energy-momentum quantum uncertainties was already explored elsewhere [8][9][10]; without the concept of negentropy, the role of correlations' negative entropy was described in our study on metal melting [11]. Other applications of negentropy are to be found in the study of black holes [12], in microbial life [13], in the field of the quantum mechanics information [14] and, finally, in the study of nanoparticles [15].…”

“…
The Comments are explicitly related to contents of two published papers: actual [1] and [2]. A third paper [3], where the measured screening potential liquid-solid difference is explained using the correlation entropy S − , should also be considered.

The mechanism described in the published paper [1] that increases the kinetic energy of light nuclei undergoing nuclear fusion, usually low energy deuterons accelerated against a host environment with implanted deuterons, does not substitute the electronic screening mechanism (as the standard Salpeter screening, the adiabatic or other proposed stationary or dynamic versions).
