2.Mutual data challenges entropy bounds (arXiv)
Writer : H. Casini
Summary : We think about some formulations of the entropy bounds on the semiclassical stage. The entropy S(V) localized in a area V is divergent in quantum discipline concept (QFT). As a substitute of it we concentrate on the mutual data I(V,W)=S(V)+S(W)-S(Vcup W) between two completely different non-intersecting units V and W. This can be a low power amount, unbiased of the regularization scheme. As well as, the mutual data is bounded above by twice the entropy akin to the units concerned. Calculations of I(V,W) in QFT present that the entropy in empty area can’t be renormalized to zero, and should be really very giant. We discover that this entropy because of the vacuum fluctuations violates the FMW certain in Minkowski area. The mutual data additionally provides a exact, cutoff unbiased that means to the assertion that the variety of levels of freedom will increase with the amount in QFT. If the holographic certain holds, this factors to the important non locality of the bodily cutoff. Violations of the Bousso certain would require conformal theories and huge distances. We speculate that the presence of a small cosmological fixed may stop such a violation
