Inflation without inflaton: A model for dark energy
The interaction between two initially causally disconnected regions of the Universe is studied using analogies of noncommutative quantum mechanics and the deformation of Poisson manifolds. These causally disconnect regions are governed by two independent Friedmann-Lema\^{\i}tre-Robertson-Walker (FLRW) metrics with scale factors $a$ and $b$ and cosmological constants ${\mathrm{\ensuremath{\Lambda}}}_{a}$ and ${\mathrm{\ensuremath{\Lambda}}}_{b}$, respectively. …
