Phonon focussing patterns: Monte Carlo simulation of the motion of ballistic phonon beams in cubic crystals

Abstract
We present a full end-user version of the program MCFOC which simulates ballistic phonon transport of quasimomentum and energy in crystalline media of cubic symmetry, media which have many important technological applications and are extensively studied. The program produces phonon energy and quasimomentum focussing patterns on an arbitrary oriented lattice plane and for a sample having the form of a perpendicular parallelepiped. The results of simulations can be applied to the analysis of ex...

Nature of problem
During the last decade the spectroscopy of phonon images of crystalline solids has been developed. This spectroscopy provides information about phonon surfaces of constant energy which is not available from the familiar acoustic and neutron scattering measurements. From these phonon images one can infer information about the local geometrical properties of surfaces of constant energy of phonons [1] or knowledge to assist in the testing of the existing models of vibrational dynamics of crystallin ...

摘要
我们提出了程序MCFOC的完整终端用户版本，该程序可模拟立方对称晶体介质中准动量(quasimomentum)与能量的弹道声子(phonon)输运——这类介质拥有诸多重要的技术应用场景，且已被广泛研究。该程序可在任意取向的晶格平面上，以及呈直平行六面体形态的样品中，生成声子能量与准动量聚焦模式。模拟结果可应用于对……

问题本质
近十年来，晶体固体的声子图像光谱学已得到长足发展。该光谱学可提供关于恒定能量声子面的相关信息，而这类信息是常规声学与中子散射测量无法获取的。通过这些声子图像，人们可以推导出声子恒定能量面的局部几何特性信息，或是获得有助于检验现有晶体振动动力学模型的相关知识……
