晶格上的超对称破缺：N=1 Wess-Zumino模型
Supersymmetry breaking on the lattice: the N=1 Wess-Zumino model
摘要：
本文利用Wilson费米子和费米子圈公式讨论了N=1 Wess-Zumino模型在二维格点上的自发超对称破缺。在该配方的费米子符号的问题有关的消失的威滕指数可以绕过和模型可以非常有效地模拟使用最近推出的开放费米子弦算法。我们提出了第一个结果的超对称破缺相变和草图的重新规范化的临界耦合在连续极限的初步确定。
英文摘要：
We discuss spontaneous supersymmetry breaking in the N=1 Wess-Zumino model in two dimensions on the lattice using Wilson fermions and the fermion loop formulation. In that formulation the fermion sign problem related to the vanishing of the Witten index can be circumvented and the model can be simulated very efficiently using the recently introduced open fermion string algorithm. We present first results for the supersymmetry breaking phase transition and sketch the preliminary determination of a renormalised critical coupling in the continuum limit.
