PHSI 424: Advanced Quantum Mechanics II (PHSI)
Two level atom coupled to a single mode of the Electromagnetic field.
This course presents a treatment of nonrelativistic manybody theory with applications to quantum optics and degenerate quantum gases.
 Prerequisites
 PHSI 423. PHSI 336 strongly recommended.

and search for PHSI 453, 424, 405.
There were a couple of embargoed years. Anything pre 2009 is not immediately relevant (old paper structure).
Exam Format
 2 hours, closed book
 3 questions of equal weight. Choose 2.
Question format
 questions begin with a qualitative/descriptive component, then lead into applications.
 Because it is closed book, and only 2 hours, questions will generally involve quite a bit of "scaffolding", that is, you won't be asked to reproduced a large proof, but rather to work your way through one or two problems, in several parts.
 To avoid early "sudden death", some key steps will be of the form: "show that ..." with the equation given.
 It will be assumed you are very familiar with chapters 2,3.
 For applications, focus on chapters 4,6,7,8,9. Problems could be closely related to an assignment question you have done, to other problems in the notes, or to an example we discussed in lectures.
Key concepts
 Pictures of time evolution
 Simple quantum systems: twolevel atom, simple harmonic oscillator
 Interactions between light and matter
 Fundamentals processes in quantum optics and open quantum systems
 Born approximation and scattering theory
