TL;DR: In this article, it was shown that due to frequency dispersion of the dielectric permittivity, an optical system can have symmetry at isolated frequency points only, and that the ideal symmetry-breaking transition cannot be observed by simply varying the frequency.
Abstract: We discuss phase transitions in $\mathcal{PT}$-symmetric optical systems. We show that, due to frequency dispersion of the dielectric permittivity, an optical system can have $\mathcal{PT}$ symmetry at isolated frequency points only. An assumption of the existence of a $\mathcal{PT}$-symmetric system in a continuous frequency interval violates the causality principle. Therefore, the ideal symmetry-breaking transition cannot be observed by simply varying the frequency.

TL;DR: In this paper, it was shown that lensing of the CMB anisotropies by the large-scale structure gives strong extra constraints on this model, limiting the fraction as $Fl8%$ at 2σ confidence level.
Abstract: It has been recently suggested [Z. Berezhiani, A. D. Dolgov, and I. I. Tkachev, Phys. Rev. D 92, 061303 (2015)] that emerging tension between cosmological parameter values derived in high-redshift (CMB anisotropy) and low-redshift (cluster counts, Hubble constant) measurements can be reconciled in a model which contains a subdominant fraction of dark matter decaying after recombination. We check the model against the CMB Planck data. We find that lensing of the CMB anisotropies by the large-scale structure gives strong extra constraints on this model, limiting the fraction as $Fl8%$ at $2\ensuremath{\sigma}$ confidence level. However, investigating the combined data set of the CMB and conflicting low-$z$ measurements, we obtain that the model with $F\ensuremath{\approx}2%\char21{}5%$ exhibits better fit (by $1.5\char21{}3\ensuremath{\sigma}$ depending on the lensing priors) compared to that of the concordance $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ cosmological model.
