论文摘要
在这封信中，我们表明，固体中位错动态模式的分散关系对晶格对称性很敏感。特别是，我们表明，在IR中，不喜欢的分散关系在大约各向同性晶格中对动量产生了对数的依赖性，而对于非异端晶格而言，线性项主导。对于各向同性和各向异性晶格而言，脱位张力的重新归一化组流量与众不同。
In this letter we show that the dispersion relation for the dynamical modes of dislocations ("dislons") in solids is sensitive to the lattice symmetries. In particular, we show that in the IR, the dislon dispersion relation develops a logarithmic dependence on momenta for approximately isotropic lattices whereas for non-isotropic lattices, the linear term dominates. The renormalization group flows for dislocation tension are shown to be distinct for isotropic and anisotropic lattices.
