Shear modulus of a body-centered cubic Coulomb crystal of ions is calculated by thermodynamic perturbation theory taking into account ion motion. Classic and quantum regimes of ion motion are considered. The calculations in the classic range of high temperatures agree well with previous Monte Carlo simulations. In this case, the shear modulus is given by a sum of a positive contribution due to ...

The previously formulated surface-enhanced SE Raman optical activity ROA theory is based on a multipole electromagnetic field expansion. The field of molecule and colloid particles is induced by the excitation light. Although this semistatic polarization is not the only enhancement mechanism, it provides a good basis for understanding of the phenomenon. However, the mathematical expressions bec...

We evaluate the effect of ions on the electric response of an insulting liquid by means of the total electric polarization induced in a cell by an external field. The limiting surfaces are assumed blocking and identical and the ions pointike nonpolarizable charged particles. The analysis is limited to the case where the selective ionic adsorption is absent, in such a manner that in the absence ...
