Superluminal communications have been proposed to solve the Einstein, Podolsky and Rosen (EPR) paradox. So far, no evidence for these superluminal communications has been obtained and only lower bounds for the superluminal velocities have been establ

As shown in the \emph{EPR} paper (Einstein, Podolsky e Rosen, 1935), Quantum Mechanics is a non-local Theory. The Bell theorem and the successive experiments ruled out the possibility of explaining quantum correlations using only local hidden variabl

An EPR experiment with polarized entangled photons is performed to test the Eberhard model. According to the Eberhard model, quantum correlations between space-like separated events are due to a superluminal communication signal propagating in a pref

The azimuthal anchoring energy at the interface between the nematic liquid crystal 5CB and a photosensitive polymer(para-PVCN-F)is measured using a high accuracy reflectometric method. The anchoring well is represented by the Rapini-Papoular function

A new transmitted light method has been used to measure the azimuthal anchoring energy coefficientWat the interface between the nematic liquid crystal 5CB and a rubbed polyimide substrate. This method overcomes the typical drawbacks of the transmitte

The elastic free energy Fel of nematic liquid crystals is a truncated power expansion of the free energy F in the gradients of the director field n(r) . In principle, the cut-off distortion length for Fel could be estimated from the direct comparison

In this paper we report an accurate optical method for measuring the azimuthal director angle and the azimuthal anchoring energy for a nematic liquid crystal. The method is fully automated and provides a direct measurement of the azimuthal angle. The

We investigate the existence of a surface static friction torque τF on nematic liquid crystal molecules at a solid substrate. We find the upper limit τF = 1.2 × 10−6 erg/cm2.

We analyze the spatially inhomogeneous dynamic behaviour of a +~/2 twisted NLC layer in a magnetic field. When a magnetic field H is applied in the layer plane at a suitable angle fl with respect to the easy axis on the first surface, the relaxation
