We construct $\alpha$-attractor versions of hybrid inflation models. In these models, the potential inflaton field $\varphi$ is uplifted by second $\chi$. This uplifting ends due to a tachyonic instability with respect $\chi$, which appears when becomes smaller than some critical value $\varphi_{c}$. large $N$ limit, models have standard universal predictions. particular, $n_{s }= 1- {2 \over N...

Several cosmological tensions have emerged in light of recent data, most notably the inferences parameters ${H}_{0}$ and ${\ensuremath{\sigma}}_{8}$. We explore possibility alleviating both these simultaneously by means Albrecht-Skordis ``quintessence'' potential. The field can reduce size sound horizon ${r}_{s}^{*}$ while concurrently suppressing power matter density fluctuations before it com...
