    "abstract": "We make a novel observation about the decoherence phenomenon of the fermion\nin the Witten\u0027s supersymmetric (SUSY) quantum mechanical model. It is shown\nthat, when the bosonic partner in the SUNY model is unobservable in a certain\nenergy scale, the quantum coherence meant by the superposition of fermion\nstates can not be preserved for a long time due to the quantum decoherence\ninduced by the overlooked boson. This refers to a supercharge superselection\nrule similar to the charge superselection. We numerically calculate the\ndecoherence factor characterizing the extent of decoherence . The obtained\nresult shows the periodic decoherence with finite quantum jump. Some analytic\nresults under the harmonic approximation for the superpotential can be obtained\nto confirm the numerical calculations.",
