  Recent progresses using state-of-the-art experimental techniques have
motivated a number of new insights on heavy fermion physics. This article gives
a brief summary of the author's research along this direction. We discuss five
major topics including: (1) Development of phase coherence and two-stage
hybridization; (2) Two-fluid behavior and hidden universal scaling; (3) Quantum
phase transitions and fractionalized heavy fermion liquid; (4) Quantum critical
superconductivity; (5) Material-specific properties. These cover the most
essential parts of heavy fermion physics and lead to an emerging global picture
beyond conventional theories based on mean-field or local approximations.
