Dear group, This is a follow up to Patrick's e-mail about the series on energy transfer. We will try to organize it in such a way that the series is self-contained without assume your profounds knowledge of quantum mechanics from undergraduate studies. We will try to follow Mukamel from the end of chapter 2 and onwards. Undergraduates are welcome too. Just one pre-requisite. Please send me an e-mail by this Wednesday if you are interested in seriously attending and I will plan the calendar accordingly and times accordingly. I will start with a short review of time-dependent quantum mechanics, green functions, line-shape, density matrices, Liouville space and projection methods. Patrick we will follow up with electrodynamics review, and chapter 4 of Mukamel. The continuation will be with Chapter 5 and 6 and if you feel you want to contribute and present, you are more than welcome, otherwise, you will have to stick with Patrick and I, until the end of the karma :). Second quick thing. I am in need of my Tannor book, and it seems someone borrowed it from the desk in the aquarium. So, if you took it please give a call to my cell 857-9982355 and we can arrange delivery. Last thing, the series will start next week (the week of May 4 after Alan is back from Mexico). Enjoy the weekend. -Alejandro
