Core: inter-particle: improve example: Hexagonal lattices with basis: choose other correlation length, and explain things
|Status:||Backlog||Start date:||31 Jul 2019|
The current correlation length is extremely small (1R). This is unrealistic; it obscures the Bragg rods from the 2D lattice; and it exacerbates the unphysical symmetry breaking. Let's choose a larger correlation length.Expand the header comment to explain:
- that there is an unphysical symmetry breaking, and where it comes from;
- that there is a finite correlation length, what it is meant to represent, why it is needed, and what effects and problems are to be expected when smaller or larger values are chosen.
