Hyperscaling Violating Solution in Coupled Dilaton-Squared Curvature   Gravity
  Considering a model with Coupled Dilaton-Squared Curvature terms and a dilatonic potential which replace the cosmological constant, we present an analytic hyperscaling violating solution which is the generalization of arXiv:1305.3279 for non zero $\theta$. We show that a specific coupling between dilaton and the squared curvature terms produces a simple logarithmic behavior for the dilaton. By imposing the null energy condition and stability constraints, we investigate the allowed regions for the parameters of this model. We then study the perturbations around $\mathrm{AdS_4} $ in the UV and $\mathrm{\mathrm{AdS}_2\times \mathbb{R}^2} $ in the IR of the Einstein-Weyl gravity which can support an intermediate hyperscaling violating solution in order to resolve the $\mathrm{IR} $ singularity of the metric in 4d.
