# Critical solutions of nonminimally coupled scalar field theory and first-order thermodynamics of gravity

@article{Faraoni2022CriticalSO, title={Critical solutions of nonminimally coupled scalar field theory and first-order thermodynamics of gravity}, author={Valerio Faraoni and Pierre-Antoine Graham and Alexandre Leblanc}, journal={Physical Review D}, year={2022} }

Analytical solutions of nonminimally coupled scalar ﬁeld cosmology corresponding to critical scalar ﬁeld values constitute a potential challenge to the recent ﬁrst-order thermodynamics of scalar-tensor gravity (a formalism picturing general relativity as the zero-temperature equilibrium state for modiﬁed gravity). The critical solutions are unstable with respect to homogeneous perturbations, hence unphysical.
