Cardy-Verlinde Formula and entropy bounds in Kerr-Newman-AdS4/dS4 black holes backgrounds
The Cardy-Verlinde formula is further verified by using the Kerr-NewmanAdS4 and Kerr-Newman-dS4 black holes. In the Kerr-Newman-AdS4 spacetime, we find that, for strongly coupled CFTs with AdS duals, to cast the entropy of the CFT into the Cardy-Verlinde formula the Casimir energy must contains the terms −n ( JΩH + QΦ 2 + QΦ0 2 ) , which associate with rotational and electric potential energies...
متن کاملCardy-Verlinde Formula and Kerr-Newman-AdS4 and two rotation parameters Kerr-AdS5 black holes
The Cardy-Verlinde formula, which expresses the entropy of the conformal field theory in terms of its total energy (or the extensive energy), Casimir energy and radius of the unit sphere S, is further verified by using the Kerr-Newman-AdS4 and the two rotation parameters Kerr-AdS5 black holes. For the Kerr-Newman-AdS4 black hole we find that to cast the entropy of the conformal field theory int...

متن کاملThe Entropy Function for the extremal Kerr-(anti-)de Sitter Black Holes
Based on the entropy function formalism, we consider the extremal Kerr(anti-)de Sitter black holes in 4-dimensions. Solving differential equations exactly, which are obtained by extremizing the entropy function, we find agreement of the result with Bekenstein-Hawking entropy. Concerning the higher derivative corrections, we extend the computation to the case with Gauss-Bonnet term.
متن کاملNonthermal nature of extremal Kerr black holes
Liberati, Rothman and Sonego have recently showed that objects collapsing into extremal Reissner-Nordström black holes do not behave as thermal objects at any time in their history. In particular, a temperature, and hence thermodynamic entropy, are undefined for them. I demonstrate that the analysis goes through essentially unchanged for bodies collapsing into extremal Kerr black holes. PACS: 0...
