Quantum optics + Atom optics Quantum optics + Atom optics Introduction: Light Atom (light up the beginning of life) (Smallest particle) Understanding + exploring light The most important two aspects in (thermal light Laser) modern physics Classical optics QED Quantum optics Study quantum statistics What ? (EM radiation (light) quantum nature) + Interaction of EM with matter After laser was invented, scientists Why ? faced these questions: What is the nature of radiation (light)? How many types of states does light have? How does light matter? How ? I hope that the course will tell you something! Theoretical methods Experimental study Where to start ? Back to 1900-1930 (golden time for physics) Several problems haunting around physics: 1) Blackbody radiation spectrum (1889-1901?) Eν Rayleigh-Jeans T (classical theory) prism Experiment E Rayleigh-Jeans wien ν Classical wien Theory Fails ! plank λ 2) Photoelectric effect ν Experiment (H. Hertz, 1888)
