中文摘要	A series of cerium-based heavy fermion materials is studied using a combination of local density functional theory and the many-body Gutzwiller approximation. Computed orbital-dependent electronic mass enhancement parameters are compared with available experimental data extracted from measured values of the Sommerfeld coefficient. Gutzwiller density functional theory is shown to remarkably follow the trends across a variety of Ce compounds and to give important insights into the phenomenon of orbital-selective mass renormalization which in turn allows for a better understanding of a wide spread of data.
