Mermin wagner hohenberg theorem

Web17 sep. 2015 · The Mermin–Wagner (–Hohenberg) theorem says that, in two spatial dimensions at nonzero temperature, there can be no symmetry-breaking transition where a continuous symmetry is broken. The symmetry broken in a superconductor is phase-rotation symmetry: a nonzero Ψ implies a certain complex phase. – Stephen Powell Sep 17, … Web那就是说,二维和三维系统的分别,就是二维没有稳定的非对称相。. 我们如何理解?. 其实,可以理解成二维的偶合项可以做成对非对称项足够大的破坏,因为二维的偶合只作用在两个方向上,但三维的足够小的偶合不足以破坏,因为偶合有三个方向的作用 ...
