402-0521-66LModern Aspects in Surface Science Research: Techniques and ApplicationsW6 KP2V + 1UO. Gürlü
KurzbeschreibungThe Course will treat the subjects of the crystal structure of bulk and surfaces, imaging surfaces with electrons and ions, general scanning probe microscopy methods, Scanning Tunnelling Microscopy, Atomic force microscopy, Electronic structure of the bulk and surfaces, Photoelectric emission, STM and AFM spectroscopy. The various techniques will be illustrated with examples from modern research.
LernzielIt is the aim of this course to provide a review of modern aspects in surface science research.
InhaltCourse description
The course will start with an overview of the fundamentals of bulk crystals and a reminder on the x-ray diffraction from crystals. We will continue with the extension of the alphabet of bulk crystal structure to surfaces and the nomenclature of surface reconstructions and interesting structures like moiré patterns will be introduced. Following the two introductory weeks, we will dwell in to the realm of imaging the surfaces. We will start with electron beam based imaging and analysis techniques of surfaces. Scanning Electron Microscopy (SEM), Low Energy Electron Diffraction (LEED) and Low Energy Electron Microscopy (LEEM) will be discussed. Imaging with ion beam based techniques like Low Energy Ion Scattering (LEIS) and He-ion microscopy will be touched upon. Following these, probe microscopy techniques will be explored starting with the topografiner and continuing with Scanning Tunnelling Microscopy (STM). Basics of Atomic Force Microscopy (AFM) will follow. Imaging is a fundamental part of efforts on understanding surfaces. Yet, a through understanding and capability of generating and manipulating novel surface and interface systems can only be achieved by studying the electronic structure of surfaces. In order to investigate the electronic structure of surface and interface systems, a basic knowledge of the bulk electronic structure is necessary. So, introductory concepts on the electronic structure of the bulk and low dimensional systems will be discussed. Then, the basics of photoelectron emission form surfaces will be given. In the final two weeks of the course an overview of the spectroscopic modes of scanning probes and atomic scale electron spectroscopy will be introduced.

- Magnetism in solids (mechanisms producing inter-atomic exchange interaction in solids, crystal field).
- Magnetic order at finite temperatures (Ising and Heisenberg models, mean-field approximation, low-dimensional magnetism)
- Dipolar interaction in ferromagnets (shape anisotropy, frustration and modulated phases of magnetic domains)
- Spin physics in the time domain (Larmor precession, resonance phenomena, Bloch equation, Landau-Lifshitz-Gilbert equation, superparamagnetism)
SkriptLecture notes and slides are made available during the course, through the Moodle portal.
Voraussetzungen / BesonderesThe former title of this course unit was "Fundamental Aspects of Magnetism". This lecture insists on the fundamental aspects -- quantum physics and statistical physics of magnetism.
Applications to nanoscale magnetism will be considered from the perspective of basic underlying principles.

402-0715-00LLow Energy Particle PhysicsW6 KP2V + 1UA. S. Antognini, P. A. Schmidt-Wellenburg
KurzbeschreibungLow energy particle physics provides complementary information to high energy physics with colliders. In this lecture, we will concentrate on selected experiments, using mainly neutrons and muons, which have significantly improved our understanding of particle physics today.
LernzielThe course aims to provide an introduction to selected advanced topics in low energy particle physics with neutrons and muons.
InhaltLow energy particle physics provides complementary information to high energy physics with colliders. At the Large Hadron Collider one directly searches for new particles at energies up to the TeV range. In a complementary way, low energy particle physics indirectly probes the existence of such particles and provides constraints for "new physics", making use of precision and high intensities.

Besides the sensitivity to effects related with new physics (e.g. lepton flavor violation, symmetry violations, CPT tests, search for electric dipole moments, new low mass exchange bosons etc.), low energy physics provides the best test of QED (electron g-2), the best tests of bound-state QED (atomic physics and exotic atoms), precise determinations of fundamental constants, information about the CKM matrix, precise information on the weak and strong force even in the non-perturbative regime etc.

In this lecture, we will concentrate on selected experiments, using mainly neutrons and muons, which have significantly improved our understanding of particle physics today. Starting from a general introduction on high intensity/high precision particle physics and the main characteristics of muons and neutrons and their production, we will then focus on the discussion of fundamental problems and ground-breaking experiments:

- Production and characteristics of muon and neutron beams
- Ultracold neutron production
- Measurement of the neutron lifetime and electric dipole moment
- The neutron in the gravitational field and its electric charge
- Muon and neutron decay correlations
- Lepton flavour violations with muons to search for new physics
- What atomic physics can do for particle physics and vice versa
- Laser experiments at accelerators
- From myonic hydrogen to the proton structure and bound-state QED
- From pionic hydrogen to the strong interaction and effective field theories
- etc.

402-0822-13LIntroduction to IntegrabilityW6 KP2V + 1UN. Beisert
KurzbeschreibungThis course gives an introduction to the theory of integrable systems, related symmetry algebras and efficients calculational methods.
LernzielIntegrable 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 various notions of integrability in classical mechanics, quantum mechanics and quantum field theory. We discuss efficient methods for solving such models as well as the underlying enhanced symmetries.
