用中子散射获得的固体体性质的量子关联
Quantum correlations in bulk properties of solids obtained from neutron scattering
摘要：
我们证明，非弹性中子散射技术可以用来间接检测和测量量子磁性材料VODPO 4中的纠缠和不和谐量化的宏观量子关联。1天20分。通过分析孤立的V4+自旋二聚体中磁激发的中子散射数据，获得了量子关联的量2。我们的定量分析表明，这种材料的临界温度可达Tc = 82.5 K，此时量子纠缠降为零。值得注意的是，量子不和谐甚至可以在Tc = 300 K下存活，并且可以用于室温量子器件。考虑到自旋-轨道（SO）耦合，我们还从理论上预测了纠缠度会随着自旋-轨道耦合的增强而显著增强，并且临界温度Tc也随着自旋-轨道耦合的增强而增大.
英文摘要：
We demonstrate that inelastic neutron scattering technique can be used to indirectly detect and measure the macroscopic quantum correlations quantified by both entanglement and discord in a quantum magnetic material, VODPO4 . 1D2O. The amount of quantum correlations is obtained 2 by analyzing the neutron scattering data of magnetic excitations in isolated V4+ spin dimers. Our quantitative analysis shows that the critical temperature of this material can reach as high as Tc = 82.5 K, where quantum entanglement drops to zero. Significantly, quantum discord can even survive at Tc = 300 K and may be used in room temperature quantum devices. Taking into account the spin-orbit (SO) coupling, we also predict theoretically that entanglement can be significantly enhanced and the critical temperature Tc increases with the strength of spin-orbit coupling.
