Triangular Trimers on the Triangular Lattice: An Exact Solution
Triangular Trimers on the Triangular Lattice: An Exact Solution
A model is presented consisting of triangular trimers on the triangular lattice. In analogy to the dimer problem, these particles cover the lattice completely without overlap. The model has a honeycomb structure of hexagonal cells separated by rigid domain walls. The transfer matrix can be diagonalised by a Bethe Ansatz …
