摘要：

Using Majorana fermions to represent spins we reexamine the Kondo lattice model for heavy fermions. The simplest decoupling procedure provides a realization of odd-frequency superconductivity, with resonant pairing and surfaces of gap zeros. Spin and charge coherence factors vanish linearly with the energy on the Fermi surface, predicting a linear specific heat, but a T3 NMR relaxation rate. Possible application to heavy fermions is suggested.
