DESI results: Hint towards coupled dark matter and dark energy

Chakraborty, Amlan, Chanda, Prolay K., Das, Subinoy et al.

Understand

We investigate a scenario where a dark energy quintessence field $\phi$ with positive kinetic energy is coupled with dark matter.

With two different self-interaction potentials for the field and a particular choice of the coupling function, we show explicitly how the observable effective equation of state parameter $w_{\rm eff}$ for the dark energy field crosses the phantom barrier ($w_{\rm eff} = -1$) while keeping the equation of state of the quintessence field $w_\phi > -1$.
With appropriate choices of parameters, $w_{\rm eff}$ crosses the phantom divide around redshift $z\sim 0.5$, transitioning from $w_{\rm eff} <-1$ in the past to $w_{\rm eff}>-1$ today.
This explains DESI observations well.
