经典二维Wigner晶体的熔化

The melting of the classical two dimensional Wigner crystal

Martial Mazars

摘要:

本文用Monte-Carlo方法研究了点粒子通过$1/r$ -Coulomb势相互作用时经典二维Wigner晶体的熔化。在足够大的体系中发现六方相。利用多重直方图方法和有限尺寸标度理论,我们证明了流体/六角晶系的相变是弱一级相变。没有一组临界指数,符合一个Kosterlitz无相变和有限尺寸标度分析,这种转变,已被发现。

英文摘要:

We report an extensive Monte-Carlo study of the melting of the classical two dimensional Wigner crystal for a system of point particles interacting via the $1/r$-Coulomb potential. A hexatic phase is found in systems large enough. With the multiple histograms method and the finite size scaling theory, we show that the fluid/hexatic phase transition is weakly first order. No set of critical exponents, consistent with a Kosterlitz-Thouless transition and the finite size scaling analysis for this transition, have been found.
