| Abstract: | An analytic expression for the normal_state retarded electronic self_energy in a phenomenological Nearly Antiferromagnetic Fermi Liquid (NAFL) has been derived in the one_loop approximation. In the low_temperature and low_frequency limit, it has been found that the self_energy approaches to that in a canonical Fermi liquid. Using the calculated self_energy, the spectral distribution of the quasiparticles is briefly discussed. |
| Keywords: | nearly antiferromagnetic Fermi liquid electronic self_energy spectral distribution |
