关于超对称Lifshitz场论

On Supersymmetric Lifshitz Field Theories

Shira Chapman, Yaron Oz, Avia Raviv-Moshe

摘要:

我们考虑场论,表现出一个超对称的Lifshitz标度与两个真正的超荷。这些理论可以用随机量子化的语言来表述。本文构造了任意维中偶动力学指数为$z=2k$的具有旋转单重费米子的自由场超对称代数。我们分析了$2+1$和$3+1$时空维中的经典和量子$z=2$超对称相互作用,揭示了一个保持超对称的量子图解相消。随机量子化表明,在$(3+1)$维量子理论中,Lifshitz标度不变性被破坏.

英文摘要:

We consider field theories that exhibit a supersymmetric Lifshitz scaling with two real supercharges. The theories can be formulated in the language of stochastic quantization. We construct the free field supersymmetry algebra with rotation singlet fermions for an even dynamical exponent $z=2k$ in an arbitrary dimension. We analyze the classical and quantum $z=2$ supersymmetric interactions in $2+1$ and $3+1$ spacetime dimensions and reveal a supersymmetry preserving quantum diagrammatic cancellation. Stochastic quantization indicates that Lifshitz scale invariance is broken in the $(3+1)$-dimensional quantum theory.
