Quintessence background for $5D$ Einstein-Gauss-Bonnet black holes
  As we know that the Lovelock theory is an extension of the general relativity to the higher-dimensions, in this theory the first and the second order terms correspond to the general relativity and the Einstein-Gauss-Bonnet gravity, respectively. We obtain a $5D$ black hole solution in Einstein-Gauss-Bonnet gravity surrounded by the quintessence matter, and also analyze their thermodynamical properties. Owing to the quintessence corrected black hole, the thermodynamic quantities have also been corrected except for the black hole entropy, and phase transition is achievable. The phase transition for the thermodynamic stability, is characterized by a discontinuity in the specific heat at $r=r_C$, with the stable (unstable) branch for $r < (>) r_C$.
