Why does the dispersion curve flattens at high symmetry points which are exactly at the centre between two neighbouring lattices in the k-space?

When we see the dispersion diagram of crystal lattices, we find that the dispersion curve flattens at those high symmetry points which are at the centre between two neighbouring lattices in the...

Reference paper for highest value of permittivity/susceptibility for an infinite SC lattice?

I am looking at a problem related to the Clausius-Mossotti equation. The Clausius-Mossotti equation is given by, chi = (4*pi*n*alpha)/ (1 - 4*pi*n*alpha/3) where, chi: susceptibility n: number...
