Density oscillations in multi-component molecular mixtures
M. Apostol
The excitation spectrum of the density collective oscillations is computed for multi-component molecular mixtures both with Coulomb and (repulsive) short-range interactions. Distin…

Density oscillations in a model of water and other similar liquids
M. Apostol, E. Preoteasa
It is suggested that the dynamics of liquid water has a component consisting of O^{-2z} (oxygen) anions and H^{+z} (hydrogen) cations, where z is a (small) reduced effective electr…

On defects in solids
M. Apostol
The thermodynamical potential for dilute solutions is rederived, generalized and applied to defects in solids. It is shown that there are always defects in solids, i.e. there is no…

On the low-dimensional solids and their melting
M. Apostol
It is shown that the one- and two-dimensional solids may exist and melt
