Mesoscopics and the fundamental properties of space

The so-called mesoscopic systems recently undergoing intensive study in physics occupy in a certain sense an intermediate position between micro- and macroscopic systems. It is possible to establish a connection between the properties of mesoscopic systems and the existence of the additional spinor coordinates of space-time introduced along with $x$, $y$, $z$, $t$ in quantum field theory for the realization of supersymmetry. It actually turns out to be possible to prove the reality of the additional coordinates.
