abstract = {We study holographic entanglement entropy and revisit thermodynamics and
confnement in the dilaton-gravity system. Our analysis focuses on a solvable class of
backgrounds that includes AdS and linear dilaton spacetimes as particular cases, with some
results extended to general warped metrics. A general lesson is that the behavior of the
holographic theory is tied to the bulk curvature singularities. We fnd that a singular
background is confning if and only if i) the singularity coincides with a boundary or ii) it
is the linear dilaton. In the former case, for which the singularity cuts of spacetime, we
demonstrate that both entanglement entropy and thermodynamics exhibit a frst order phase
transition. In the linear dilaton case we fnd instead that both entanglement entropy and
thermal phase transitions are of second order. Additionally, along the process we thoroughly
derive the radion efective action at quadratic order.},
