We present band structure calculations and quantum oscillation measurementson LuRh2Si2, which is an ideal reference to the intensively studied quantumcritical heavy-fermion system YbRh2Si2. Our band structure calculations show astrong sensitivity of the Fermi surface on the position of the silicon atomszSi within the unit cell. Single crystal structure refinement and comparison ofpredicted and observed quantum oscillation frequencies and masses yield zSi =0.379c in good agreement with numerical lattice relaxation. This value of zSiis suggested for future band structure calculations on LuRh2Si2 and YbRh2Si2.LuRh2Si2 with a full f electron shell represents the "small" Fermi surfaceconfiguration of YbRh2Si2. Our experimentally and ab initio derived quantumoscillation frequencies of LuRh2Si2 show strong differences with earliermeasurements on YbRh2Si2. Consequently, our results confirm the contribution ofthe f electrons to the Fermi surface of YbRh2Si2 at high magnetic fields. Yetthe limited agreement with refined fully itinerant local density approximationcalculations highlights the need for more elaborated models to describe theFermi surface of YbRh2Si2.
