摘要：

We address the question whether a medium featuring p + rho = 0, dubbed Lambda-medium, has to be necessarily a cosmological constant. By using effective field theory, we show that this is not the case for a class of media comprising perfect fluids, solids and special super solids, providing an explicit construction. The low energy excitations are non trivial and lensing, the growth of large scale structures can be used to clearly distinguish Lambda-media from a cosmological constant.
