B3 Oxford physics course Updated +Created
users.physics.ox.ac.uk/~lvovsky/B3/ contain assorted PDFs from between 2015 and 2019
Syllabus reads:
  • Multi-electron atoms: central field approximation, electron configurations, shell structure, residual electrostatic interaction, spin orbit coupling (fine structure).
  • Spectra and energy levels: Term symbols, selection rules, X-ray notation, Auger transitions.
  • Hyperfine structure; effects of magnetic fields on fine and hyperfine structure. Presumably Zeeman effect.
  • Two level system in a classical light field: Rabi oscillations and Ramsey fringes, decaying states; Einstein
  • A and B coefficients; homogeneous and inhomogeneous broadening of spectral lines; rate equations.
  • Optical absorption and gain: population inversion in 3- and 4-level systems; optical gain cross section; saturated absorption and gain.
Professor in 2000s seems to be
But as of 2023 marked emeritus, so who took over?
Ewart is actually religious:
This dude is pure trouble for Oxford!
History of stimulated emission Updated +Created
First postulated by Einstein in 1917 on his paper Zur Quantentheorie der Strahlung" ("On the Quantum Theory of Radiation") as a more elegant way to rederive Planck's law as part of the Einstein coefficients framework.
At that time there was no other physical evidence supporting the existence of the concept except that it looked more elegant.
