摘要
在自洽的格林函数理论框架下,讨论了二维Kagome'晶格海森堡模型的基态性质.结果说明系统的基态是自旋液体态,而每个自旋的能量是Eg/NSJ=-0.859,与对应的数值模拟结果符合得极好.
Within the self-consistent Green's function theory, the ground-state property of the two-dimensional Heisenberg antiferromagnet on the Kagome' lattice is discussed. The results show that the ground-state energy per site is which is in very good agreement with the numerical simulations.
