摘要:

确定了具有局域两格点相互作用和周期边界条件的一维哈密顿量的能谱的精确解。二格点哈密顿量与二面体群D_3的Drinfeld二重化D(D_3)给出的对称代数可换。因此,该模型描述了非阿贝尔任意子之间的局部相互作用,融合规则由D(D_3)的不可约表示的张量积分解给出。利用一组相互交换的转移矩阵所满足的函数关系,得到了求精确解的Bethe不等式。

英文摘要:

The exact solution for the energy spectrum of a one-dimensional Hamiltonian with local two-site interactions and periodic boundary conditions is determined. The two-site Hamiltonians commute with the symmetry algebra given by the Drinfeld double D(D_3) of the dihedral group D_3. As such the model describes local interactions between non-Abelian anyons, with fusion rules given by the tensor product decompositions of the irreducible representations of D(D_3). The Bethe ansatz equations which characterise the exact solution are found through the use of functional relations satisfied by a set of mutually commuting transfer matrices.
