Velocity-position correlation experiment

In velocity-change NMR the variables q and q 2 replace the axes ki and kz in Fig. 5.4.5, and ui and V2 replace r and r2 (Fig. 5.4.12). In a coordinate frame rotated by 45° the difference coordinate corresponds to acceleration a and the other to velocity v, so that this exchange experiment can be read as a velocity-acceleration correlation experiment. Following the coordinate transformations (5.4.21) for position-change spectroscopy, the following coordinate transformations apply for velocity-change spectroscopy. 

For instance, in Classical Mechanics, we can take as X the initial positions and velocities...). Moreover, in a situation involving two correlated measurements onto two separated subsystems. Quantum Mechanics will very seldom predict a violation of Bell s Inequalities. Without being exhaustive, we can point out to important necessary conditions for a sensitive experiment (according to Quantum Mechanics) ...
