摘要：

Very recently, the de Haas-van Alphen effect in the heavy fermion superconductor CeCu2Si2 was observed by M. Hunt et al. We report the band structure calculation and Fermi surface of CeCu2Si2 within the local density approximation. The slender arms of the hole sheet can explain the angular dependence of the measurements. The mass enhancement factor is up to 6 in the measured field.
