physics631	Quantum Optics Tu 14-16, Th 8-10, HS, IAP
	Instructor(s):	F. Vewinger
	Prerequisites:	Optics and Atomic Physics Lectures, Quantum Mechanics
	Contents:	The lecture will deal with the quantized version of the light field. We will discuss the (observable) differences between a classical and a quantum light field, and we will try to shed some light on the concept of a "photon". Special focus will be put on the description of the state of a field. While the density matrix contains all relevant information, it is in many cases infinite in size, and descriptions in phase space are more convenient. Some of them allow to distinguish between classical states (as the thermal Planck radiation) and non-classical states (as squeezed states or Schrödinger cat states). We will also discuss the problem of the interaction between a single atom and a quantized light field, the so-called Jaynes-Cummings model. The lecture is an experimental one, which means we will discuss how the theoretical concepts of quantum optics can be measured in the lab, and what signatures of the quantization are important. The course will cover: - Quantization of the light field - Classical and nonclassical states of the light field - Coherence properties of light fields - Phase-space representations and their measurement - Cavity QED - Schrödinger cat states - Introduction to quantum information theory

physics775	Nuclear Reactor Physics We 10-12, SR I, HISKP
	Instructor(s):	F. Klein
	Prerequisites:
	Contents:	Preamble: This lecture was a part of the regular scheme over decades at the university of Bonn, given in summer terms. After leave of absence of the last lecturer in charge it was removed from the written lecture announcements, but is now again offered for continuation for at least the running term to comply with the relevance of the subject. By dictate of rules following the Corona crises classical lectures in halls are not adequate for the time being. As for all other lectures ways to present the lectures by online transmission are presently investigated and prepared. Corresponding information will be communicated as soon as possible. (Planned) contents: In broad society Nuclear Fission Reactors are mostly known for their role in production of electrical energy. However, their importance goes much beyond: breeding of important radionuclides for medical and technical applications (also of fissionable material for nuclear weapons, unfortunately), sourcing neutrons for fundamental and material research, providing high neutrino fluxes for measurements of neutrino properties and more. The lecture will elaborate on the underlying nuclear physics, basic principles of nuclear reactor operation and control, waste management (storage, transmutation e.g.), analysis of severe accidents and aforementioned applications. The current research, status and perspectives of fusion reactors will also be addressed, tentatively by invitation of an original researcher involved in the projects at Garching and Greifswald.

	Instructor(s):	T. Reiprich
	Prerequisites:	Introductory astronomy course.
	Contents:	X-rays are emitted from regions where the Universe is hot and wild. The lecture will provide an overview of modern X-ray observations of all major X-ray sources. This includes, e.g., comets and planets in our solar system; Galactic systems like extrasolar planets, cool and hot stars, remnants of exploded stars, isolated white dwarfs and neutron stars, cataclysmic variables, close binaries with neutron stars and black holes, hot interstellar medium, and the Galactic center region; extragalactic X-ray sources like spiral and elliptical galaxies, galaxy clusters, intergalactic medium, and active galactic nuclei, i.e., supermassive black holes lurking in the centres of galaxies. The X-ray emission and absorption processes as well as current and future space-based instruments used to carry out such observations will be described, including the eROSITA space telescope to be launched in 2019. In the accompanying lab sessions, the participants will learn how to download, reduce, and analyze professional X-ray data from a satellite observatory.
	Literature:	A script of the lecture notes will be provided.

astro847	Optical Observations Fr 11-13, Raum 0.012, AIfA Exercises: Mo 9
	Instructor(s):	T. Schrabback, M. Tewes
	Prerequisites:	Astronomy introduction classes
	Contents:	Optical CCD and near infrared imaging, conducting and planning observing runs, detectors, data reduction, catalogue handling, astrometry, coordinate systems, photometry, spectroscopy, photometric redshifts, basic weak lensing data analysis, current surveys, ground-based data versus Hubble Space Telescope observations, how to write observing proposals. Practical experience is gained by obtaining and analysing multi-filter CCD imaging observations of galaxy clusters using the 50cm telescope on the AIfA rooftop.
	Literature:	Frederick R. Chromey: To Measure the Sky
	Comments:	The class has a strong focus on hands-on observations and data analysis. It should be particularly useful for students who consider conducting a master's thesis project which involves the analysis of optical imaging data from professional telescopes (e.g. wide-field imaging data or Hubble Space Telescope observations).
astro849	Multiwavelength observations of galaxy clusters Mo 16-17:30, Raum 0.008, AIfA Exercises: 1 hr. by appointment
	Instructor(s):	T. Reiprich, F. Pacaud
	Prerequisites:	Introductory astronomy course.
	Contents:	Aims of the course: To introduce the students into the largest clearly defined structures in the Universe, clusters of galaxies. In modern astronomy, it has been realized that a full understanding of objects cannot be achieved by looking at just one waveband. Different phenomena become apparent only in certain wavebands, e.g., the most massive visible component of galaxy clusters -- the intracluster gas -- cannot be detected with optical telescopes. Moreover, some phenomena, e.g., radio outbursts from supermassive black holes, influence others like the X- ray emission from the intracluster gas. In this course, the students will acquire a synoptic, multiwavelength view of galaxy groups and galaxy clusters. Contents of the course: The lecture covers galaxy cluster observations from all wavebands, radio through gamma-ray, and provides a comprehensive overview of the physical mechanisms at work. Specifically, the following topics will be covered: galaxies and their evolution, physics and chemistry of the hot intracluster gas, relativistic gas, active supermassive black holes, cluster weighing methods, Sunyaev-Zeldovich effect, gravitational lensing, radio halos and relics, tailed radio galaxies, and the most energetic events in the Universe since the big bang: cluster mergers.

astro851	Stellar and solar coronae Th 13-15:15, Raum 0.01, MPIfR Exercises: 1 hr. by appointment
	Instructor(s):	M. Massi
	Prerequisites:
	Contents:	T Tauri (young stellar systems not yet in Main Sequence) and RS CVn systems (evolved stellar systems that already left the Main Sequence), although very diverse systems, have similar flare activities observed at radio and X-ray wavelengths. The flares in both systems are several orders of magnitude stronger than those of the Sun. The origin of this activity, defined "coronal activity", depends on the convective zone, the rotation, the formation and dissipation of magnetic fields. In general terms: This is a mechanism of the same type as on the Sun, but enforced by the binary nature of these systems. In these lectures we will explore a link between the amplification of initial magnetic fields by dynamo action in several rotating systems ( Sun, binary systems and accretion discs around black holes) and the release of magnetic energy into a corona where particles are accelerated. Together with the basic theory there will be as well illustrated the latest progress in the research on stellar coronal emission derived from recent space missions and high-resolution radio observations.
