Ruppeiner geometry and 2D dilaton gravity in the thermodynamics of black holes
Yun Soo Myung, Yong-Wan Kim, Young-Jai Park
We resolve the controversial issue of the geometric approach to the black hole thermodynamics. The geometric description of the equilibrium thermodynamics comes from Ruppeiner geom…

Phase transition for black holes with scalar hair and topological black holes
Yun Soo Myung
We study phase transitions between black holes with scalar hair and topological black holes in asymptotically anti-de Sitter spacetimes. As the ground state solutions, we introduce…

New attractor mechanism for spherically symmetric extremal black holes
Yun Soo Myung, Yong-Wan Kim, Young-Jai Park
We introduce a new attractor mechanism to find the entropy for spherically symmetric extremal black holes. The key ingredient is to find a two-dimensional (2D) dilaton gravity with…
