我们提供了一个介绍,最近的超对称理论,在一个或多个真实的超对称在非零晶格间距不变的晶格配方。这些包括在四维中N=4 SYM的特别有趣的情况。我们讨论的方法的基础上扭曲的超对称性和orbifold解构技术,并显示其等价性的情况下规范理论。精确超对称性的存在减少了,在某些情况下消除了微调的需要,以实现在目标理论的完全超对称性下的连续极限不变。我们讨论开放的问题。
We provide an introduction to recent lattice formulations of supersymmetric theories which are invariant under one or more real supersymmetries at non-zero lattice spacing. These include the especially interesting case of N=4 SYM in four dimensions. We discuss approaches based both on twisted supersymmetry and on orbifold–deconstruction techniques and show their equivalence in the case of gauge theories. The presence of an exact supersymmetry reduces and in some cases eliminates the need for fine-tuning to achieve a continuum limit invariant under the full supersymmetry of the target theory. We discuss open problems.
