Entropy bounds in cosmology and conformal field theories
Abstract
We study the ratio of the entropy to the total energy in conformal field theories at finite temperature. For the free field realizations of N=4 super YangMills theory in D=4 and the (2,0) tensor multiplet in D=6, the ratio is bounded from above. The corresponding bounds are less stringent than the recently proposed Verlinde bound. For strongly coupled CFTs with AdS duals, we show that the ratio obeys the Verlinde bound even in the presence of rotation. For such CFTs, we point out an intriguing resemblance in their thermodynamic formulas with the corresponding ones of twodimensional CFTs. The discussion is based on hepth/0101076.
