晶体缺陷的弹道特性
Ballistic properties of crystalline defects
摘要：
我们介绍了一个领域理论的形式主义，使直接研究的位错和间隙动力学。给出了这种缺陷的能量的显式表达式。我们提供链接到早期的数值，离散弹性，时间相关的金斯堡-朗道，和其他方法所寻求的许多作者的缺陷动力学问题。本文中介绍的形式主义可以扩展到处理许多其他系统。除了在位错介导的晶体熔化中大量研究的作用外，缺陷动力学最近由于其在各种电子和当前感兴趣的其他系统中的可行作用而获得了很大的兴趣。这些系统包括但不限于量子霍尔液体的条纹相、解决各种掺杂氧化物（包括高温铜酸盐超导体、镍酸盐和锰酸盐）中条纹相熔化的理论、超固体中的缺陷以及胶体晶体。
英文摘要：
We introduce a field theoretic formalism enabling the direct study of dislocation and interstitial dynamics. Explicit expressions for the energies of such defects are given. We provide links to earlier numerical, discrete elastic, time dependent Ginzburg Landau, and other approaches sought by numerous authors for the problem of defect dynamics. The formalism introduced in this article may be extended to address many other systems. Apart from their heavily studied role in dislocation mediated crystal melting, defect dynamics recently gained much interest due to their viable role in various electronic and other systems of current interest. These systems include, yet are not limited to, stripe phases of Quantum Hall liquids, theories addressing the melting of stripe phases in various doped oxides (including the high temperature cuprate superconductors, the nickelates, and manganates), defects in supersolids, as well as colloidal crystals.
