Using previous results and general thermodynamical formalism,an expression is obtained for the specific heat per particle under constant volume of a degenerate non-relativistic electron gas on a 1D lattice.The result is a non-linear function of the temperature,and it could have applications in studies of quasi one-dimensional organic metals.
This is a short review of the methodology of static high pressure exeperiments in diamond anvil cells,and some of their possible applications an astrophysics.As the paper was originally published in 1993.,an addendum hints at some of the recent developements in the field.
Preliminary results of a theoretical determination of the basic parameters of the internal structure of the five Uranian satellies are presented.
Continuing previous work and using a simple change of variables, an analytical equation of state for a degenerate non-relativistic Fermi gas in a magnetic field is proposed.
Using the semiclassical theory of dense matter proposed by P.Savic and R.Kasanin,the mean molecular masses of the Galilean satellites of Jupiter are determined.The calculated values are fitted by plausible combinations of chemical elements,and the results are in good agreement with the observations by "Galileo".Possible cosmogonical explanations are briefly discussed.
We review recent research on the Milky Way galaxy and try to investigate whether its shape is similar to other barred galaxies. The emphasis is given on microlensing research because this method can be useful in determining the shape of the Galaxy with the minimal set of assumptions. By analyzing plots of the microlensing optical depth, $τ$ as a function of galactic coordinates for different values of the axis ratio, $q$ of the galactic halo, we have shown that observations are best described by a flattened halo with $0.2 ^<_\sim q ^<_\sim 0.6$.
In the sixties,the first author and R.Kasanin have started developing a mean field theory of dense matter.This paper presents a short review of the basic ideas of the theory,and discusses some examples of its applications,which range from DAC experiments to modelling of planetary interiors.
An analytical expression for Fermi-Dirac integrals of arbitrary order is presented,and its applicability in obtaining the EOS of a degenerate,non-relativistic,Fermi gas is discussed.
The purpose of this note is to present a possible explanation of the spectral distorsions that could be observed in the CMBR spectrum.We propose that distor- sions of the order of $y \sim 10^{- 6}$ can be interpreted as a consequence of radiative decay of massive tau neutrionos.We have also obtained a constraint on the value of the decaying neutrino mass.
Using the Hubbard model on a 1D lattice and the "memory function" approach,we have calculated the electrical conductivity of a 1D system of correlated electrons on a lattice. We have determined the temperature and frequency profiles of the conductivity. Effects of changes of the band filling on the conductivity were also briefly discussed.The results were compared with experimental data on the Bechgaard salts, and the agreement is satisfactory.
The aim of this contribution is to present expressions for the bulk modulus of a material and its pressure derivative,obtained by using the semiclassical theory of dense matter proposed by P.Savic and R.Kasanin. Some possibilities for the application of these expressions are briefly discussed.
Nine years ago,working within the framework of theoretical dense matter physics,the present author has determined the chemical composition of the Galileian satellites of Jupiter.A few months ago,in the flyby of the GA- LILEO spaceprobe,some of the theoretical predictions were confirmed.
This is a review of the main physical ideas and examples of applicability in astrophysics and pure physics of a semiclassical theory of dense matter proposed by Pavle Savic and Radivoje Kasanin in the early sixties. A hypothesis, advanced by Savic with the aim of solving the problem of the origin of rotation of celestical bodies,will also be discussed. The paper is dedicated to the memory of Pavle Savic, who died recently.
The chemical potential of the electron gas on a one-dimensional lattice is determined within the discrete Hubbard model. The result will have applications in studies of transport properties of quasi one-dimensional organic conductors such as the Bechgaard salts.
