Spectroscopy and the Quantum Description of Matter FYST20, Spring Term 2010Welcome to the spring term 2010 homepage of the "Spectroscopy and the Quantum Description of Matter" course. We will start the course with a start meeting on 19th January 2010, 15.15, in H530 at the Department of Physics. The course is intended to show you how one can use spectroscopy methods to gain a quantum mechanical understanding of the properties of different forms of matter. Therefore we will study both certain aspects of the quantum mechanical description of matter as well as different spectroscopy methods. Teachers
Joachim Schnadt, joachim.schnadt@sljus.lu.se, phone: 046  2220469 ScheduleA schedule is available from here. To some extent we will be able to modify it according to the students' needs  we will discuss possible changes during the start meeting. Form of teaching
Lectures: The teacher will typically give a rather brief presentation and then we will discuss both in smaller groups and with the entire course. This requires that you read the material, which is handed out during the preceding lecture, prior to the meeting. Examination
Handin problems (25% of the final grade). Marks

Hähner and the excerpt on XPS from the book by Attard and Barnes. You also may get started with reading the compendium on the interaction of matter and light, even though we will get started with that one not before next week. If you don't understand everything and don't know all the concepts  it doesn't matter. Try instead to focus on understanding what actually is going on! Thursday, 21st January 2010We have discussed xray photoelectron spectroscopy (XPS) and xray absorption spectroscopy (XAS) in groups. The questions on the question sheet were used as a basis for your discussions. In the common discussion we took up XPS using this powerpoint presentation as a guide, and we will continue with discussing XAS next time. Until our next meeting on Tuesday, 26th January 2010, please read the first part of the compendium on the interaction of matter and light (around half of it will do until Tuesday; the rest you will have to read until the meeting on Tuesday, 2nd February 2010). Tuesday, 26th January 2010In the first part of the meeting, Joakim will present the project on the core and valence electronic structure of molecules (see project information above). We will then continue with our discussion of xray absorption spectroscopy. Furthermore we will get started with the interaction of matter and light using the questions on sheet 1 and sheet 2. Tuesday, 2nd February 2010Due to the snow storm no lecture today. Thursday, 4th February 2010We go on with discussing the interaction of light and matter. Tuesday, 9th February 2010We will, finally, finish off our discussion of the interaction of light and matter. We'll then getting started with discussing two methods for quantum mechanical calculations, namely the HartreeFock and Density functional theory (DFT) methods. Reading: a short excerpt from J. M. Hollas: Modern Spectroscopy, pp 199200, who nicely introduces the idea of the HartreeFock method; the section on the Hartree and HartreeFock methods in Haken & Wolf: The Physics of Atoms and Quanta, section 19.4; and the section on DFT in A. Groß: Theoretical Surface Science, section 3.3. Reading instructions can be found here. The questions for our discussion are found on the HF/DFT question sheet. Thursday, 10th February 2010Today, it is time to choose the subject for your project work. Here is a list with suggestions:
We will also talk about how to write a present and prepare and give a presentation. As an example we will use the article on the discovery of the C_{60} fullerene. Instructions for your own report and the project can be found here. The requirements for the report and oral presentation can be found here. If time allows, we will get started with looking at Xray photoelectron spectroscopy on molecules. Reading for this part is as follows:
Tuesday, 16th February 2010Today's subject is chemical bond in molecules. Thursday, 18th February 2010Today's subject is symmetry in molecules. We'll also meet for a couple of XPS measurements at MAXlab. Here you find the handin exercise
on the measurements performed at MAXlab. You also need the following files: Tuesday, 23rd February 2010
Thursday, 25th February 2010, Thursday, 4th March 2010
The topic of the two meetings is photoelectron spectroscopy  or rather various aspects relevant to photoelectron
spectroscopy. The questions for our discussion as well as reading instructions are provided on the
Discussion questions sheet (it is from last years  sorry,
I didn't have the time to prepare a new question sheet).
After that we'll continue with the discussion of XAS, which we started on 2nd March (see below, actually). Relevant reading is Georg Hähner's review article on XAS. Tuesday, 2nd March 2010Denis introduces the basics of xray absorption spectroscopy (XAS). Tuesday, 9th March 2010Today we'll finish the discussion of XAS by briefly comparing three methods, which provide information on the unoccupied states of a sample: XAS, 2PPES, and IPES. Then we get started on angleresolved ultraviolet photoemission. Relevant reading is the following:
Thursday, 11th March 2010After finishing the discussion of ARUPS we'll have a look at Scanning tunneling microscopy (STM). Prior to the lecture please read the article by A. D. Gottlieb and L. Wesoloski in Nanotechnology.
