ELECTRONIC STRUCTURE AND FERMI SURFACES OF HEAVY FERMION LuRh2Si2
The electronic properties of LuRh2Si2 are studied by electronic band structure calculation based on the density functional theory within the local density approximation. The Lu-5d and Rh-4d states play important roles for the electronic properties of LuRh2Si2. Those states are located near the Fermi level and hybridize with each other. Our calculation shows that there are three pieces of Fermi surfaces which are bowl, jungle gym and small cylinder types.
