We present a general strategy to simulate a D+1-dimensional quantum system using a D-dimensional one. We analyze in detail a feasible implementation of our scheme using optical lattice technology. The simplest nontrivial realization of a fourth dimension corresponds to the creation of a bi-volume geometry. We also propose single- and many-particle experimental signatures to detect the effects of the extra dimension.
我们提出了一种使用 D 维系统模拟 D+1 维量子系统的通用策略。我们详细分析了使用光学晶格技术实现我们方案的可行性。第四维的最简单非平凡实现对应于创建双体积几何形状。我们还提出了单粒子和多粒子实验特征，以检测额外维度的影响。
