In this Letter, we shall investigate whether there are Bell-type inequalities for systems of N qubits which are violated by all inseparable states. It can be shown that there is such a Bell-type inequality and violating it is equivalent to being inse

Bell's inequality violation is related to the breakdown of symmetry of photonic field states. The states allowing the violation are characterized by a parameter γ associated with the interaction of the nonlinear medium and radiation. The violation i

We identify all states of two particles which lead to maximal violation of Bell's inequality. They are straightforward extensions of the singlet state of two spinors.

We show that Bell's inequality will be violated by a general class of mixed states. We examine the role of the Schmidt decomposition in determining whether pairs of systems from a three-system state will violate the Bell theorem.

We prove that any non-product state of two-particle systems violates a Bell inequality.

We consider a general globally hyperbolic universe uniformly populated with stable light leptons and derive limits on neutrino masses by analysing its large-scale properties.

This paper develops a quantitative model version of Mugur-Schachter's “reflection” model of Bell's experiment. We show that his nonlocal, but Einstein-separable, model leads to violations of Bell's inequality similar to those predicted by quantum

A violation of Bell's inequality is predicted in the system of correlated electromagnetic field modes present in an optical 8-port homodyne detector. In this system all of the field modes are of the same polarization, and the correlated field modes a

We consider two models which can violate Bell's inequality. In a local model violation of Bell's inequality is a proof that the probability scheme must contain a nondistributive sublattice. In a distributive scheme violation is a proof that the model

We have discussed some schemes for measuring the diffusion coefficient for positive muons in metals, using diffusion over macroscopic distances. The method offers some promise of yielding diffusion information over wider temperature ranges and a grea
