二维Lindemann熔化判据
Lindemann melting criterion in two dimensions
摘要:
它表明,林德曼的熔化标准可以制定为二维经典固体使用统计力学参数。用这个公式表示,熔化温度的表达式在三维和二维中是等效的。此外,在二维林德曼的熔化标准基本上符合Berezinskiii-Kosterlitz-Thouless-Halperin-Nelson-Young熔化条件的位错解约束。
英文摘要:
It is demonstrated that the Lindemann's criterion of melting can be formulated for two-dimensional classical solids using statistical mechanics arguments. With this formulation the expressions for the melting temperature are equivalent in three and two dimensions. Moreover, in two dimensions the Lindemann's melting criterion essentially coincides with the Berezinskii-Kosterlitz-Thouless-Halperin-Nelson-Young melting condition of dislocation unbinding.
