On SU(2) anomaly and Majorana fermions (1402.7283v2)
Published 26 Feb 2014 in physics.gen-ph and cond-mat.str-el
Abstract: In this paper a loophole in the SU(2) gauge anomaly is presented. It is shown that using several topological tools a theory can be designed that implements the quantization of a single Weyl doublet anomaly free while keeping the non-abelian character of the particle in the theory. This opens the perspective for non-Abelian statistics of deconfined particle like objects in 3+1 dimensions and for applications in Quantum Computing. Moreover, if this loophole cannot be closed, old arguments related to anomaly cancelations must be reviewed.
