Ground states of a classical triangular lattice

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The energies and displacements of a triangular lattice with nearest and next-nearest neighbor interaction are calculated for the groundstates. A nonlinear onsite potential acts perpendicular to the plane. Structures with low periodicity determine the various states in the parameter space. The stability of the different phases is investigated.
