S=1/2kagome反铁磁体低能自旋激发的结构因子

Structure factor of low-energy spin excitations in a S=1/2 kagome antiferromagnet

Zhihao Hao, Oleg Tchernyshyov

摘要:

在kagome上S=1/2海森堡反铁磁体的基态可以看作是束缚成小而重的单重对的费米子自旋的集合。这个系统中的低能磁激发对应于将电子对分裂成单个自旋子。本文计算了中子与独立自旋对非弹性散射的结构因子。

英文摘要:

The ground state of the S=1/2 Heisenberg antiferomagnet on kagome can be viewed as a collection of fermionic spinons bound into small, heavy singlet pairs. Low-energy magnetic excitations in this system correspond to breaking the pairs into individual spinons. We calculate the structure factor for inelastic neutron scattering from independent spinon pairs.
