Tunneling effect by means of the instantons

  1. Apr 8, 2009 #1
    I've recently find out that is possible to describe tunneling effect by means of the instantons.
    Of course there are other methods to compute the transmission probability (WKB for example), but the real utility of this technique is that it can be applied in Quantum Field Theory (and also in condensed matter physics). So I wonder: what exactly can you achieve in QFT by the use of instantons? Do you know any other application of this technique?
    Thanks
