Translational invariance of Coulomb series and symmetric potentials in crystals
Eugene V. Kholopov
It is shown that Coulomb series are to be considered within a special mode of summation so as to describe bulk properties of crystals. The translational invariance is then an expli…

Crystal potentials under invariant periodic boundary conditions at infinity
Eugene V. Kholopov
The definiteness of bulk electrostatic potentials in solids under periodic boundary conditions defined in an invariant manner has been proved in the general case of triclinic symme…
