SUMMARY

The discussion centers on the scattering and emission processes involving a two-level atom subjected to light. When the atom transitions from the ground state to the excited state and subsequently emits a photon, this phenomenon is classified as a scattering process. If the emitted photon has the same frequency as the incident light, it is identified as Rayleigh (elastic) scattering. Conversely, if the emitted photon has a different frequency, the process is termed Raman (inelastic) scattering.

PREREQUISITES
  • Understanding of two-level atomic systems
  • Knowledge of photon emission and absorption
  • Familiarity with Rayleigh and Raman scattering concepts
  • Basic principles of quantum mechanics
NEXT STEPS
  • Study the principles of two-level atomic transitions
  • Explore the mathematical framework of Rayleigh scattering
  • Investigate the mechanisms of Raman scattering
  • Learn about quantum optics and its applications
USEFUL FOR

Physicists, quantum mechanics students, and researchers in optical sciences will benefit from this discussion, particularly those focusing on atomic interactions with light.

Suppose I have a two-level atom trapped in a certain area, initially in ground state. I have a light shining on it, the atom jump from ground state to the excited state and emission a photon spontaneously. Can I say this is a scattering process?

Yes. In the case of re-emission of the same frequency it's Rayleigh (elastic) scattering and if it's a different one (inelelastic) then it's Raman scattering.
