    Singular Fermi Liquid Low Energy Collective Fluctuation
    (Addis Ababa University, 2005-07) Yimer, Seid; Bedassa, Tesgera (PhD)
    Landau’s Fermi liquid theory is analyzed theoretically. The explanation for singularity which arise due to break-down of the theory in one dimension is considered. In particular , the low energy collective fluctuations is emphasized by using the method of static and dynamic screening. The transverse conductivity is deduced by making the use of macroscopic transport equation taking in-to account electron-electron interaction
