physics737 BCGS Intensive Week (Advanced Topics in Photonics and Quantum Optics): Intensive week on topological insulators - Introduction to topological insulators and their implementations in artificial matter setups
13.03.2017 - 17.03.2017, HS, IAP
  Instructor(s): A. Alberti, J. Asbóth, F. Vewinger
  Prerequisites: - The course is recommended for graduate students in the Master program
- Good knowledge of basic quantum mechanics is expected
- Familiarity with basic concepts in condensed matter physics (Bloch theorem, energy bands, etc.) is recommended
- No prior knowledge of topology is assumed
  Contents: The intensive week consists of lectures introducing graduate students to the very active research field of topological insulators. Participants are
required to have good knowledge of basic quantum mechanics and familiarity with basic concepts in condensed matter physics (Bloch theorem,
energy bands, etc.). No prior knowledge of topology is assumed.

The main body of the intensive week is a course held by J. K. Asbóth, based on the lecture notes “A Short Course on Topological Insulators”, freely
available at https://arxiv.org/abs/1509.02295. Through simple one- and two-dimensional model Hamiltonians, participants will acquire a good
physical understanding of the core concepts of topological insulators. Among the questions covered: What is topological in a band insulator? What
are edge states? How is their number given by the so-called bulk-boundary correspondence principle? How and against what are edge states
protected? This is complemented by A. Alberti, presenting a selection of modern experiments demonstrating topological effects in ultracold atoms
and nanophotonics setups. Additionally, guest speakers will give an introduction to “frontier” research topics in this field. The course will be
accompanied by laboratory tours, exercise and interactive discussion sessions in the afternoon.

physics652 Seminar Photonics/Quantum Optics
Mo 14-16, HS, IAP
  Instructor(s): F. Vewinger
  Prerequisites: Bachelor education in physics
  Contents: Modern quantum physics builds on a few key experiments which started a new field or settled a long standing debate. An example for the former is trapping of ions or dark state physics, for the latter one can e.g name Bose-Einstein condensation or Bell experiments. Especially the "newer" experiments are not covered in the Bachelor studies, as they require a broad theoretical background.

The seminar has two goals: To provide in-depth knowledge about selected key experiments in the field of quantum optics, and to provide practical training in preparing and presenting excellent talks. During the first meeting the organizers will present a list of topics from which each active participant of the seminar can select one. The list will also be available prior to the course on ecampus, where early birds can pick a topic in advance.

For each topic literature will be provided. Starting with this material the active participants of the seminar will familiarize themselves with the content. This will be done by discussions as well as by further literature search. Based on the accumulated knowledge an outline for each talk will be made and finally the viewgraphs will be prepared. Then the talk will be presented in the seminar. Typical duration of the talk is 45 minutes. After the talk there will be a discussion about the content. And, as a second part of the discussion, technical issues of the talk will be analyzed. Finally, a short written summary of the talk will be prepared and posted in the internet.

Preparation of the talk is a serious amount of work. It is highly recommended to start already at the beginning of the lecture time to familiarize yourself with the content.

A list of topics is available on ecampus.
  Literature: Will be given in the seminar or on ecampus
  Comments: Early birds can reserve a topic, a list can be found on ecampus.

astro849 Multiwavelength observations of galaxy clusters
Mo 15.30-17, Raum 0.008, AIfA
Exercises: 1 hr. by appointment
  Instructor(s): T. Reiprich
  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.
  Literature: Lecture script and references therein.
astro851 Stellar and solar coronae
Th 13-15:15, Raum 0.01, MPIfR
Exercises: 1 hr. by appointment
  Instructor(s): M. Massi
  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.

astro8504  Lecture on Advanced Topics in Modern Astrophysics: The physics of compact objects
Th 9-11, Raum 0.008, AIfA
Exercises: 1 hr. by appointment
  Instructor(s): T. Tauris
  Prerequisites: BSc in Physics
  Contents: A general introduction to the basic, fascinating physics of compact objects (neutron stars, white dwarfs and
black holes) and their binary interactions. We introduce the theory of degenerate Fermi gases and apply it to
simple equations of state for white dwarfs and neutron stars. We investigate the structure, cooling and
evolution of white dwarfs and neutron stars and compare with observational properties. We analyse the
formation, evolution and detection of X-ray binaries, including the dynamical effects of asymmetric
supernovae. In particular, we discuss the formation of millisecond radio pulsars and also the recent
discoveries associated with the extremely magnetic neutron stars called magnetars. Finally, we learn about
the nature and the detection of gravitational waves which will soon open a new window to the Universe.

  • The course is aimed at starting master students who did not obtain
    a formal education in scientific computing during their Bachelor
    studies. The educational objectives overlap with the Bonn Bachelor
    courses physik130 (Einführung in die EDV) and physik441 (Numerische
    Methoden der Physik). Hence, the course is also suited for students,
    who would like to refresh and to extend their knowledge of these courses.

  • The entire course will be hands-on with each student working and
    performing practical exercises on an own computer.

  • The maximum number of participants for this course is 18 students
