Possible Realization of Odd Frequency Pairing in Heavy Fermion Compounds

Using Majorana Fermions to represent spins we re-examine 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 $T^3$ NMR relaxation rate. Possible application to heavy fermions is suggested.
