Description

  1. What is the Jaynes-Cummings (JC) model between a two-level system and quantized photons? What is the difference between JC and the semi-classical atom-light interaction?
  2. How does the physical system studied in the paper map to the JC model (what are the "atom" and "photon cavity")?
  3. How is the frequency of the "atom" tuned to match that of the "cavity"? How does the measured response change?
  4. What is the definition of the strong coupling regime?
  5. What is the Hamiltonian in the dispersive limit $\Delta\gg g$? Describe the transformation from the JC model to the dispersive limit?
  6. What is the physical meaning of the $\kappa$ and $\gamma$ parameters, how are they related to the measured cavity transmission and phase response in figure 2?
  7. Why is it important to achieve strong coupling regime?
  8. Which of the measurement results indicates the onset of strong coupling?
