Pairing in a system of a few attractive fermions in a harmonic trap
... fig. 3) the off-diagonal correlation falls down as expected, i.e. according to the power law g2 (x) ∼ xκ . Exponent κ depends on the interaction constant g (inset of fig. 4). The dependence on interactions is rather weak. This can be understood by noticing a small contribution of the Cooperlike pairs ...

Daniel Dennett`s Compatibilism
... Indeterministic events are unpredictable. Consequently, if any such probabilistic events occur, as Dennett admits, Laplace’s demon cannot predict the future. Information cosmology provides a second reason why such a demon is impossible. There was little or no information at the start of the universe ...

A relevant two qubit Bell inequality inequivalent to the CHSH
... We are interested in the faces of the convex set in this reduced space. These are ‘tight’ inequalities. There are of course other inequalities which are satisfied by all the points inside the past-generated set, but such inequalities are less useful for detecting non-local correlations. An inequalit ...
