Abstract | Many-body quantum physics rests on symmetry considerations that lead to two kinds of particles, fermions and bosons. Formal techniques include Hartree-Fock theory and second-quantization techniques, as well as quantum statistics with ensembles. Few- and many-body systems include atoms, molecules, the Fermi sea, elastic chains, radiation and its interaction with matter, and ideal quantum gases. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Learning objective | Basic command of few- and many-particle physics for fermions and bosons, including second quantisation and quantum statistical techniques. Understanding of elementary many-body systems such as atoms, molecules, the Fermi sea, electromagnetic radiation and its interaction with matter, ideal quantum gases and relativistic theories. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Content | The description of indistinguishable particles leads us to (exchange-) symmetrized wave functions for fermions and bosons. We discuss simple few-body problems (Helium atoms, hydrogen molecule) und proceed with a systematic description of fermionic many body problems (Hartree-Fock approximation, screening, correlations with applications on atomes and the Fermi sea). The second quantisation formalism allows for the compact description of the Fermi gas, of elastic strings (phonons), and the radiation field (photons). We study the interaction of radiation and matter and the associated phenomena of radiative decay, light scattering, and the Lamb shift. Quantum statistical description of ideal Bose and Fermi gases at finite temperatures concludes the program. If time permits, we will touch upon of relativistic one particle physics, the Klein-Gordon equation for spin-0 bosons and the Dirac equation describing spin-1/2 fermions. | |||||||||||||||||||||||||||||||||||||||||||||||||||||

402-0822-13L | Introduction to Integrability | W | 6 credits | 2V + 1U | N. Beisert | |||||||||||||||||||||||||||||||||||||||||||||||||
Abstract | This course gives an introduction to the theory of integrable systems, related symmetry algebras and efficients calculational methods. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Learning objective | Integrable systems are a special class of physical models that can be solved exactly due to an exceptionally large number of symmetries. Examples of integrable models appear in many different areas of physics including classical mechanics, condensed matter, 2d quantum field theories and lately in string- and gauge theories. They offer a unique opportunity to gain a deeper understanding of generic phenomena in a simplified, exactly solvable setting. In this course we introduce the notion and formulation of integrability in classical and quantum mechanics. We discuss various efficient methods for constructing solutions and eigenstates in these models. Finally, we elaborate on the enhanced symmetries that underly integrable models. | |||||||||||||||||||||||||||||||||||||||||||||||||||||

401-4816-22L | Geometric Methods in Mathematical Physics | W | 4 credits | 2V | M. Schiavina | |||||||||||||||||||||||||||||||||||||||||||||||||
Abstract | The course will cover selected topics in mathematical physics, focusing on their geometric underpinning. The main common denominator will be the notion of quantisation and the course material will range through several techniques to make sense of it from a mathematical standpoint. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
Learning objective | The objective of this course is to expose master and graduate students in mathematics and physics to a number of successful geometric techniques in mathematical physics. The course will provide a foundation to essential topics in symplectic and Poisson geometry and its application to fundamental questions in classical and quantum physics. It is aimed at mathematics/physics masters and graduate students with an interest but no previous background in symplectic geometry, and students who want to focus on more formal aspects of classical and quantum physics. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
