Quantum oscillations in non-Fermi-liquid metals

The temperature dependence of de Haas van Alphen (dHvA) and other quantum oscillations is governed in a Fermi liquid by the Lifshitz-Kosevich (LK) equation\footnote{see e.g. D.\ Shoenberg, {\em Magnetic Oscillations in Metals}, CUP 1984}. Several authors \footnote{e.g. A.\ Wasserman and M.\ Springford, Adv.\ Phys.{\bf 45} (1996) 471, and references therein.} have extended the LK theory to non-Fermi-liquid metals, but these treatments tend to be very technical. We will give a simple interpretation of the non-Fermi-liquid effects that arise in these theories, and will briefly discuss the possible observation of non-Fermi-liquid temperature dependence in dHvA oscillations in CeCoIn$_5$.
