Viscosity bound and causality violation.
In recent work we showed that, for a class of conformal field theories (CFT) with Gauss-Bonnet gravity dual, the shear viscosity to entropy density ratio, eta/s, could violate the conjectured Kovtun-Starinets-Son viscosity bound, eta/s > or = 1/4 pi. In this Letter we argue, in the context of the same model, that tuning eta/s below (16/25)(1/4 pi) induces microcausality violation in the CFT, re...
متن کاملCausality versus true-concurrency
Category theory has been successfully employed to structure the confusing setup of models and equivalences for concurrency: Winskel and Nielsen have related the standard models via adjunctions and (co)reflections while Joyal et al. have defined an abstract notion of equivalence, known as open map bisimilarity. One model has not been integrated into this framework: the causal trees of Darondeau ...
متن کاملCausal Pluralism versus Epistemic Causality
It is tempting to analyse causality in terms of just one of the indicators of causal relationships, e.g., mechanisms, probabilistic dependencies or independencies, counterfactual conditionals or agency considerations. While such an analysis will surely shed light on some aspect of our concept of cause, it will fail to capture the whole, rather multifarious, notion. So one might instead plump fo...
متن کاملVertebroplasty--high viscosity cement versus low viscosity cement.
The patients with intensive pain caused by the vertebra body fracture were treated by application of low viscosity cement (LVC), (Vertebroplastic, DePuy) and high viscosity cement (HVC), (Confidence, DePuy,) into the body, by means of diascopy through unilateral transpendicular approach. Application of LVC was made in 75 patients, on 109 vertebrae, and HVC was applied in 12 patients on 14 verte...
متن کاملSpace Time relaying versus Information Causality
We investigate the connection between causality and Information Theory. We show that a simple reading of Information Theory makes that quantum entanglement allows super-luminal information transfer. We show that introducing the concept of space-time information relaying partially solves the paradox of non causal information transfer. Surprisingly information causality is only dependent on the q...
