Fluctuations in the Ginzburg-Landau Theory of Dark Energy: internal (in-)consistencies in PLANCK data set

Understand

In this work, predictions of the Ginzburg-Landau theory of dark energy (GLT) for CMB lensing are studied.

• We find that the time and scale dependence of the dark energy fluctuations in this semi-phenomenological model is favored by data in several ways.
• Firstly, unlike $\Lambda$CDM, $\ell\leq801$ and $\ell>801$ ranges of the CMB angular power spectrum are consistent in this framework.
• Secondly, the lensing amplitude $A_L$ is completely consistent with unity when GLT is confronted with CMB data, even without including CMB lensing data.
