Wigner固体平均势的计算

Calculating the average potential of a Wigner solid

修正了Callaway J计算Wigner固体的平均势理论中出现的错误。以单原子的bcc和fcc结构的金属为例,建立了计算Wigner固体的平均势的理论。理论结果表明:金属晶体的平均势与晶体的晶格常数a的倒数1/a成正比。对一些常用的bcc和fcc结构的金属晶体的平均势进行了数值计算,获得了大量具有应用价值的计算结果。

A few errors occurring in the calculations of Callaway J on the average potential of a Wigner solid are corrected. With respect to the monoatomic bee and fee metals, a theory of calculating the average potentials of them is established, and the theoretical results demonstrate that the average potential is directly proportional to 1/α （α is the lattice constant of the crystal）. Moreover, a great deal of calculations of the average potentials of various bee and fcc metals are performed, and a lot of numerical results which are valuable for applications are obtained.
