格点上Leibniz规则的No-Go定理与超对称性

No-Go Theorem of Leibniz Rule and Supersymmetry on the Lattice

Mitsuhiro Kato, Makoto Sakamoto, Hiroto So

摘要:

在晶格上实现超对称性的一个障碍是莱布尼茨规则的破缺。本文证明了一个不可行定理,即在无限格体中,不可能用任何非平凡场积和差分算子构造格场论,而这些场积和差分算子必须满足下列三个性质:(i)平移不变性,(ii)局部性和(iii)Leibniz规则.然后,我们提出了一种方法来逃避不去定理通过引入无限的口味,并提出了一个格子模型的N=2超对称量子力学配备了全精确超对称。

英文摘要:

An obstacle to realize supersymmetry on a lattice is the breakdown of Leibniz rule. We give a proof of a no-go theorem that it is impossible to construct a lattice field theory in an infinite lattice volume with any nontrivial field products and difference operators that satisfy the following three properties: (i) translation invariance, (ii) locality and (iii) Leibniz rule. We then propose a way to escape from the no-go theorem by introducing infinite flavors, and present a lattice model of N=2 supersymmetric quantum mechanics equipped with the full exact supersymmetry.
