Optimal lattice configurations for interacting spatially extended particles
Laurent Bétermin, Hans Knüpfer
We investigate lattice energies for radially symmetric, spatially extended particles interacting via a radial potential and arranged on the sites of a two-dimensional Bravais latti…

On Born's conjecture about optimal distribution of charges for an infinite ionic crystal
Laurent Bétermin, Hans Knüpfer
We study the problem for the optimal charge distribution on the sites of a fixed Bravais lattice. In particular, we prove Born's conjecture about the optimality of the rock-salt al…

Magnetic domains in thin ferromagnetic films with strong perpendicular anisotropy
Hans Knüpfer, Cyrill B. Muratov, Florian Nolte
We investigate the scaling of the ground state energy and optimal domain patterns in thin ferromagnetic films with strong uniaxial anisotropy and the easy axis perpendicular to the…
