  The non-local effects induced by Majorana fermions in field theories for
condensed matter systems are deeply related to the fermion charge
fractionalization discovered by Roman Jackiw in relativistic field theories. We
show how the presence of Majorana fermions may be mimicked in pertinent
networks of spin chains inducing a spin analogue of the multi-channel Kondo
effect. The relevance of this spin analogue of the Kondo effect for networks of
Josephson arrays and Tonks-Girardeau gases is highlighted.
