中文简介:
中子散射和晶格动力学具有悠久的历史,特别是使用实验数据来改善原子间力常数。如今,实验和模拟之间仍然存在很强的协同作用,不同之处在于,从头算计算方法现在经常用于分析复杂系统的非弹性散射数据。此外,abinitio方法可以获得电子和磁性结构,后者可以通过中子散射技术直接探测。
课程简介: Neutron scattering and lattice dynamics have a long history, in particular with experimental data being used to refine inter-atomic force constants. Nowadays there is still a strong synergy between experiment and simulation, with the difference that ab initio computational methods are often now used to analyse inelastic scattering data from complex systems. In addition, abinitio methods give access to electronic and magnetic structure, the latter being directly probed by neutron scattering techniques.
关 键 词: 中子散射; 晶格动力学; 原子间力常数的实验数据; 非弹性散射数
