Abstract

Two-dimensional (2D2D) Lifshitz-like black holes in special F(R)F(R) gravity cases are extracted. We indicate an essential singularity at r=0r=0, covered with an event horizon. Then conserved and thermodynamic quantities such as temperature, mass, entropy, and the heat capacity of 2D2D Lifshitz-like black holes in F(R)F(R) gravity are evaluated. Our analysis shows that 2D2D Lifshitz-like black hole solutions can be physical solutions, provided that the cosmological constant is negative (Λ<0\Lambda<0). Indeed, there is a phase transition between stable and unstable cases by increasing the radius of AdS black holes. In other words, the 2D2D Lifshitz-like AdS black holes with large radii are physical and enjoy thermal stability. The obtained 2D2D Lifshitz-like AdS-black holes in F(R)F(R) gravity turn to the well-known 2D2D Schwarzschild AdS-black holes when the Lifshitz-like parameter is zero (s=0s=0). Also, correspondence between these black hole solutions and the 2D2D rotating black hole solutions is found by adjusting the Lifshitz-like parameter.
