Entropy bounds in cosmology and conformal field theories

چکیده
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 Yang-Mills 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 two-dimensional CFTs.

Thermodynamics of Conformal Field Theories and Cosmology

متن کاملConformal Relativity versus Brans-Dicke and Superstring Theories
We show how conformal relativity is related to Brans–Dicke theory and to low-energy-effective superstring theory. Conformal relativity or the Hoyle–Narlikar theory is invariant with respect to conformal transformations of the metric. We show that the conformal relativity action is equivalent to the transformed Brans–Dicke action for ω = −3/2 (which is the border between standard scalar field an...
متن کاملDeSitter Entropy , Quantum Entanglement and AdS / CFT
A deSitter brane-world bounding regions of anti-deSitter space has a macroscopic entropy given by one-quarter the area of the observer horizon. A proposed variant of the AdS/CFT correspondence gives a dual description of this cosmology as conformal field theory coupled to gravity in deSitter space. In the case of two-dimensional deSitter space this provides a microscopic derivation of the entro...
متن کاملCFT , Holography , and Causal Entropy Bound
The causal entropy bound (CEB) is confronted with recent explicit entropy calculations in weakly and strongly coupled conformal field theories (CFTs) in arbitrary dimension D. For CFT’s with a large number of fields, N , the CEB is found to be valid for temperatures not exceeding a value of order MP /N 1 D−2 , in agreement with large N bounds in generic cut-off theories of gravity, and with the...
متن کاملConformal transformations in classical gravitational theories and in cosmology
In recent years, the use of conformal transformation techniques has become widespread in the literature on gravitational theories alternative to general relativity, on cosmology, and on nonminimally coupled scalar fields. Tipically, the transformation to the Einstein frame is generated by a fundamental scalar field already present in the theory. In this context, the problem of which conformal f...
