Lecture Notes Dump

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… Continue reading Lecture Notes Dump

The String Theory Diet

Are you unhappy with the way you look? Feel like you’re carrying around some large extra dimensions? Want to compactify your manifold before the summer conference season gets here? If you answered “Yes!” to any of those questions, then you’re ready for the String Theory Diet! Each rich, satisfying meals of eleven-dimensional noodles, and watch… Continue reading The String Theory Diet

And the Problem is… What, Exactly?

The usual suspects are all upset about John Barrow’s crack about Richard Dawkins: When Selfish Gene author Richard Dawkins challenged physicist John Barrow on his formulation of the constants of nature at last summer’s Templeton-Cambridge Journalism Fellowship lectures, Barrow laughed and said, “You have a problem with these ideas, Richard, because you’re not really a… Continue reading And the Problem is… What, Exactly?

Lecture Notes Dump

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. Lecture 6: Non-classical light, photon anti-bunching, single-photon interference. Sadly, this exhausts the notes I had written in advance (what with one thing and another, I… Continue reading Lecture Notes Dump
