Course objectives
Quantum theory provides a fascinating picture of the behavior of particles. In addition, however, it allows one to understand why and how the electrons and the nuclei form atoms, and why and how atoms form molecules and extended systems (solids, liquids, clusters). Knowledge of the atomic composition and the geometrical structure then allows one to understand various properties of extended systems. This is not merely an understanding ``in principle'' but an understanding that allows to obtain the structure of extended systems and subsequently many properties of these systems at the qualitative and semiquantitative level (using physically transparent and mathematically relatively simple approaches) or with a fairly high precision (using sophisticated ,,ab-initio'' methods, where the only input parameters are the numbers of electrons, protons, and neutrons). Both physically transparent and simple models and some elements of rigorous quantum mechanical theory of many-electron atoms will be presented. Illustrative examples from the world of atoms, molecules, traditional solid state materials, and modern materials, that are currently under intense research, will also be given.
Learning outcomes
At the end of the course students should be able to understand the basic concepts of this field of physics, apply them in solving simple related problems, compare the results of model calculations with experimental data and/or analyze the data in terms of the models.
Syllabus
  • I. Atoms.
  • 1. Hydrogen atom: summary of the quantum mechanical description and relativistic corrections. 2. Helium atom and the concept of electron correlation. 3. Many-electron atoms. (a) Heuristic approach: Hartree equation and screening of the interaction between the nucleus and the electrons. (b) Rigorous approach using symmetry arguments and the variation principle. 4. Periodic table: explanation of the main trends.
  • II. Molecules.
  • 1. Elements of the theory of molecules: the adiabatic approximation, the Hellman-Feynman theorem and the virial theorem. 2. Quantum-mechanical description of the simplest molecules and the nature of the covalent bond.
  • III. Extended systems.
  • Two starting points. 1. Extended system as a giant molecule. 2. Extended system as a Fermi see of electrons on the background of the nuclei, justification and generalization of the Sommerfeld model. 3. Qualitative aspects of the Coulomb interaction in many-electron systems. 4. Qualitative explanation of the crystal structure of elements and of selected simple compounds.
  • IV. Basic ideas of the modern ab-initio methods, in particular the density-functional theory.

Teaching methods
Lectures and class exercises, where solutions of typical problems are presented and discussed. Illustrative examples from the world of atoms, molecules, traditional solid state materials, and modern materials, that are currently under intense research, will also be given.
Assessment methods
The examination consists of a written part (test) and an oral part. The written part is evaluated according to the number of questions answered correctly; at least one half of the questions must be answered correctly for the student to pass the examination. During the oral part, students are requested to answer 3-5 questions concerning the topic of the course. The final evaluation reflects the degree of understanding the basic concepts and applications thereof. Active presence at the class exercises, including solution of a certain amount of problems (2-3) by the students, is required.
