掺空穴的一维自旋液体的基态和激发态

Ground state and excited state of 1D spin-liquid doped with holes

基于P.Tavan的含t激发态的自旋液体模型,本文提出了描述掺有空穴的一维自旋液体的哈密顿和状态矢,并用变分法计算了基态和激发态能量,得出了能隙△与掺空穴指数δ的依赖关系。对所得结果与高Tc超导的联系作了讨论。

Based on the notion of the spin-liquid model with triplet excitations developed by P. Tavan, the reduced Hamiltonian and state vector for doped Spin -liquid is proposed in order to make a variatiOnal calculation for the ground and excited states. The dependence of the energy gap (or Tc ) on dopinq is obtained) and some discussion on the results and the superconductivity of the system are made also.
