比如Ising model( O(1) ), ϕ 和−ϕ 是等价的,经典的Heisenberg model( O(3)),把 ϕ 转任何角度都是等价的,对于这类模型,重要的只有 ϕ 的大小,因此展开应该只有偶次项,于是: F[ϕ]=∫dDr (r2ϕ2+u4!ϕ4+κ2(∇ϕ)2+⋯) 其中r,u,κ 某些待确定的温度的函数。 好的,接...

Landau-Ginzburg Modelsdoi:10.1007/1-4020-4522-0_295The action for a super Landau Ginzburg model of n chiral superfields Φ i ( i = 1,..., n) with superpotential W(Φ) is given byDuplij, StevenDuplij, Steven
For a het- erotic Landau-Ginzburg model [1–7], the nonlinear sigma model possesses only (0, 2) su- persymmetry and the superpotential is a Grassmann-odd function of the superfields which may or may not be holomorphic. These heterotic models have field content consisting of (0, 2) ...

We consider a well-known thermo-diffusive model for the propagation of a premixed, adiabatic flame front in the large-activation-energy limit. That model depends only on one nondimensional parameter β, the reduced Lewis number. Near the... CA Pereira,JM Vega - 《European Journal of Applied ...
It is argued that the presence of a nonanalytic term in the effective potential of the Ginzburg-Landau model is immaterial as far as the order of the superconductor-normal phase transition is concerned. To achieve agreement with the renormalization group, the effective potential has to be extended...
