准二聚自旋梯中的基态能量标度

On the ground state energy scaling in quasi-rung-dimerized spin ladders

P. N. Bibikov

摘要:

在周期性边界条件下,微扰地研究了梯级二聚化轻微破坏的自旋梯的基态能量密度和气体参数的大N(N为梯级数)渐近性.精确的梯级二聚自旋梯被视为参考模型。对于三种特殊的自旋梯,得到了显式的微扰公式。

英文摘要:

On the basis of periodic boundary conditions we study perturbatively a large N asymptotics (N is the number of rungs) for the ground state energy density and gas parameter of a spin ladder with slightly destroyed rung-dimerization. Exactly rung-dimerized spin ladder is treated as the reference model. Explicit perturbative formulas are obtained for three special classes of spin ladders.
