Cosmological time crystal: Cyclic universe with a small cosmological constant in a toy model approach
Cosmological time crystal: Cyclic universe with a small cosmological constant in a toy model approach
A new form time crystal has been proposed, and some of its consequences have been studied. The model is a generalization of the Friedmann-Robertson-Walker (FRW) cosmology endowed with noncommutative geometry corrections. In the minisuperspace approach, the scale factor undergoes the time periodic behavior, or Sisyphus dynamics, which allows us to …
