Stealths on $(1+1)$-dimensional dilatonic gravity

We study gravitational stealth configurations emerging on a charged dilatonic $(1+1)$-D black hole spacetime. We accomplish this by considering the coupling of a non-minimally scalar field $ϕ$ and a self-interacting scalar field $Ψ$ living in a $(1+1)$-D charged black hole background. In addition, the self-interacting potential for $Ψ$ is obtained which exhibits transitions for some specific values of the non-minimal parameter. Atypically, we found that the solutions for these stealth scalar fields do not have a dependence on the temporal coordinate.
