For those following along with my Quantum Optics class, here's a bunch of lectures about photons:
- Lecture 7: Commutators, simple harmonic oscillators, creation and annihilation operators, photons.
- Lecture 8: Coherent states of the electromagnetic field.
- Lecture 9: Number-phase uncertainty, squeezed states, interferometry.
- Lecture 10: Photon anti-correlation revisited, beamsplitters and vacuum states.
This material, unsurprisingly, produced the most panicked looks from students to this point. One of the homework problems was also to recapticulate a couple of calculations from a Phys. Rev. A (Castin and Dalibard, PRA 55, 4330 (1997)), which I think is pretty cool, though I'm not sure they appreciate it.
Also, there's a typo in the first lecture, due to copying some of my notes from a paper that uses "natural units" where the frequency is set equal to 1. I haven't bothered fixing the PDF's because, well, that would be a hassle.

The abbreviation here has a double meaning-- both "Open Access" and "Operator Algebra." In my Quantum Optics class yesterday, I was talking about how to describe "coherent states" in the photon number state formalism. Coherent states are the best quantum description of a classical light field--…
Since the previous batch of lecture notes were surprisingly popular, here's the next couple of classes worth:
Lecture 5: Stellar Interferometry, coherence, intensity correlation functions, Hanbury Brown and Twiss experiment.

In the Physics Blogging Request Thread the other day, I got a comment so good I could've planted it myself, from Rachel who asks:
It’s a term I see used a lot but don’t really know what it means – what is a “squeezed state”? What does “squeezing” mean? (in a QM context of course…)
I love this,…
I'm teaching my Quantum Optics class again this term, out of a completely different textbook than last time around-- I'm using Mark Fox's Quantum Optics from the Oxford Master Series in AMO Physics, which is more of a regular textbook. I've got six students-- four junior and senior physics majors,…
