论文摘要
键 - 纽个状态既有磁性四极杆的远距离顺序，又具有典型的自旋液体的高纠缠，因此可以将其视为旋转液体晶体。找到这样一种状态的最有前途的材料之一是BACDVO（po $ _4 $）$ _ 2 $，其中在磁性有序的低场相和高场极化相之间发现了磁性无声相。在这里，我研究了BACDVO的磁性汉密尔顿（PO $ _4 $）$ _ 2 $，对于由适合非弹性中子中子散射实验确定的汉密尔顿 - 参数，表明磁蛋白从极化状态凝结为绑定对。这是对饱和场以下键 - 纽态存在的直接理论支持。
The bond-nematic state has both long-range ordering of magnetic quadrupoles and the high entanglement typical of spin liquids, and as such can be thought of as a spin liquid crystal. One of the most promising materials in which to find such a state is BaCdVO(PO$_4$)$_2$, in which a magnetically silent phase has been found between a magnetically ordered low-field phase and the high-field polarised phase. Here I study the magnetic Hamiltonian of BaCdVO(PO$_4$)$_2$, and, for the Hamiltonian-parameters determined by fits to inelastic neutron scattering experiments, show that magnons condense out of the polarised state as bound pairs. This is direct theoretical support for the existence of a bond-nematic state just below the saturation field.
