Abstract
A tunneling conductivity between a heavy-fermion metal and a simple metallic point is considered. We show that, at low temperatures, this conductivity can be noticeably dissymmetrical with respect to the change of voltage bias. The dissymmetry can be observed in experiments on heavy-fermion metals whose electronic system has undergone the fermion-condensation quantum phase transition.
