A remark on the use of Bell inequalities. (arXiv:0912.0235v1 [physics.gen-ph])

02.12.2009 01:47    arxiv.org
In the present paper it is demonstrated that Bell's expression for localhidden variable correlation allows one to derive the quantum correlation. Thisraises questions about the use of Bell inequalities in experiments. In thepaper a CHSH violating example is given based

We demonstrate the operation of a quantum ratchet in the absence ofdissipative processes within the observation time (Hamiltonian regime). Anatomic rubidium Bose-Einstein condensate is exposed to a sawtooth-like opticallattice potential, whose amplitude is periodically modulated in time. Theratchet transport arises

Network communities help the functional organization and evolution of complexnetworks. However, the development of a method, which is both fast andaccurate, provides modular overlaps and partitions of a heterogeneous network,was rather difficult.
