Holographic Principle in the Closed Universe : a Resolution with Negative Pressure Matter
نویسنده
چکیده
A closed universe containing pressureless dust, more generally perfect fluid matter with pressure-to-density ratio w in the range ( 3 ,− 3 ), violates holographic principle applied according to the Fischler-Susskind proposal. We show, first for a class of two-fluid solutions and then for the general multifluid case, that the closed universe will obey the holographic principle if it also contains matter with w < − 3 , and if the present value of its total density is sufficiently close to the critical density. It is possible that such matter can be realised by some form of ‘quintessence’, much studied recently. PACS numbers: 98.80.Cq, 98.80.Bp

Holography in (2+1)-dimensional cosmological models
The cosmic holographic principle suggested by Fischler and Susskind has been examined in (2+1)-dimensional cosmological models. Analogously to the (3+1)-dimensional counterpart, the holographic principle is satisfied in all flat and open universes. For (2+1)-dimensional closed universes the holographic principle cannot be realized in general. The principle cannot be maintained, neither introduc...
متن کاملHolography and holographic dark energy model
The holographic principle is used to discuss the holographic dark energy model. We find that the Bekenstein-Hawking entropy bound is far from saturation under certain conditions. A more general constraint on the parameter of the holographic dark energy model is also derived.

متن کاملCosmic Holography
A version of holographic principle for the cosmology is proposed, which dictates that the particle entropy within the cosmological apparent horizon should not exceed the gravitational entropy associated with the apparent horizon. It is shown that, in the Friedmann-Robertson-Walker (FRW) cosmology, the open Universe as well as a restricted class of flat cases are compatible with the principle, w...
متن کاملHolographic Principle and Quantum Cosmology
Using the holographic entropy proposal for a closed universe by Verlinde, a bound on equations of state for different stages of the universe is obtained. Further exploring this bound, we find that an inflationary universe naturally emerges in the early universe and today's dark energy is also needed in the quantum cosmological scenario.
متن کاملCrossing the phantom divide line in the Holographic dark energy model in a closed universe
Conditions needed to cross the phantom divide line in an interacting holographic dark energy model in closed FriedmannRobertson-Walker universe are discussed. The probable relationship between this crossing and the coincidence problem is studied.
