Abstract
In this work, we study a particle creation mechanism at the expense of the energy stored in an extra dimension with the respective process of compactification, and hence the emergence of 4D space. The spacetime resulting can be the Friedmann–Robertson–Walker (FRW) type, but also can be the cosmological term plus cold dark matter (ΛCDM) type, depending on the model’s parameters. Concurrent with the compactification process we have also the homogenization process, since initially the spacetime is anisotropic.
