固体中的多量子NMR作为确定Wigner-Yanase偏斜信息的方法

Multiple quantum NMR in solids as a method of determination of Wigner-Yanase skew information

S. I. Doronin, E. B. Fel'dman, I. D. Lazarev

摘要:

在固体多量子核磁共振实验中,考虑了在不同温度和不同偶极-偶极相互作用下核自旋演化时间下,Wigner-Yanase倾斜信息与多量子核磁共振相干性的关系.结果表明,在温度$T$下的Wigner-Yanase偏斜信息等于在任何演化时间下双温度下MQ NMR谱的双二阶矩。比较了用Wigner-Yanase信息和Fisher信息得到的多自旋纠缠。

英文摘要:

A connection of the Wigner-Yanase skew information and multiple quantum (MQ) NMR coherences is considered at different temperatures and evolution times of nuclear spins with dipole-dipole interactions in MQ NMR experiments in solids. It is shown that the Wigner-Yanase skew information at temperature $T$ is equal to the double second moment of the MQ NMR spectrum at the double temperature for any evolution times. A comparison of the many-spin entanglement obtained with the Wigner-Yanase information and the Fisher information is conducted.
