摘要我们用有效的二聚体模型研究了Pd（dmit）2盐的基态性质。该模型描述了两带Hubbard模型的低能激发，并通过强耦合展开得到。通过取代阳离子同时控制费米面、态密度奇异性和二聚体模型中的磁阻挫。
Abstract We have studied the ground state properties of Pd(dmit)2 salts using an effective dimer model. This model describes low-energy excitations of the two-band Hubbard model and is derived by a strong coupling expansion. Dimensionality of the Fermi surface, density-of-states singularity, and magnetic frustration in the dimer model are simultaneously controlled by substituting the cation.
