In this talk, I will review recent theoretical studies on multipolar orders in CeB6, PrOs4Sb12, and NpO2. Their characteristic phase diagrams originating from (quasi-)quartet crystal field levels are shown to provide a good opportunity to study orbital degrees of freedom of f electrons. The important role of some experiments in studying hidden multipoles and their dynamic fluctuations is discussed.
