模拟引力是基于弯曲时空中的量子场论与某些凝聚态系统中微扰传播之间的数学同一性。但并不是每一个弯曲的时空都可以用这种方式模拟。为了使模拟引力起作用,人们不仅需要一个能产生所需度规张量的凝聚态系统,而且这个系统还必须服从它自己的运动方程。然而,与度规张量的关系通常过度决定了底层凝聚态系统的方程,以至于它们通常不能满足。在这种情况下,所需的度量没有类似物。
Analogue gravity is based on a mathematical identity between quantum field theory in curved space-time and the propagation of perturbations in certain condensed matter systems. But not every curved space-time can be simulated in such a way. For analogue gravity to work, one needs not only a condensed matter system that generates the desired metric tensor, but this system then also has to obey its own equations of motion. However, the relation to the metric tensor usually overdetermines the equations of the underlying condensed matter system, such that they in general cannot be fulfilled. In this case the desired metric does not have an analogue.
