我们讨论了非相对论共形群(薛定谔群)作为时空对称性的一种实现。我们写下一个玩具模型,在这个模型中,这个几何体是场方程的解。我们讨论了与非相对论全息术有关的各种问题。特别是,我们认为,自由费米子和费米子在幺正对应于相同的散装理论与不同的选择对应的源和一个运营商的期望值的近边界渐近。我们描述了一个扩展版本的非相对论性的一般坐标不变性,这是实现全息。
We discuss a realization of the nonrelativistic conformal group (the Schr\"odinger group) as the symmetry of a spacetime. We write down a toy model in which this geometry is a solution to field equations. We discuss various issues related to nonrelativistic holography. In particular, we argue that free fermions and fermions at unitarity correspond to the same bulk theory with different choices for the near-boundary asymptotics corresponding to the source and the expectation value of one operator. We describe an extended version of nonrelativistic general coordinate invariance which is realized holographically.
