Much of the excitement has certainly been generated by the discovery of Bell's inequality [12], a simple mathematical statement about an observable quantity which can be deduced directly from Einstein locality and which is violated by quantum mechanics. Even though the first experimental investigati ...

In Cs2CuCl4 strong scattering continuum is expected because: • low (S=1/2) spin and the frustration lead to a small ordered moment and strong quantum fluctuations • the magnon interaction in non-collinear spin structures induces coupling between transverse and longitudinal spin fluctuations additi ...

... The main reason that unitary operators are employed is that they preserve the norm and hence map states into states. Moreover, the superposition principle, which says that evolutions preserve superpositions, requires that U be linear. Of course, no physical system is really isolated except the univ ...
