physics635 Laser Spectroscopy
Tu 8-10, Th 14-16, HS, IAP
Exercises: 1 hr in groups included
VEXP, WPVEXP
  Instructor(s): F. Vewinger
  For term nos.: ab 5. Semester
  Hours per week: 3+1
  Prerequisites: Optics, Atomic physics, Knowledge in Laser physics is helpful
  Contents: The lecture gives an introduction in the field of optical spectroscopy, covering fundamental concepts as well as applications of spectroscopy.
On the fundamental side, the lecture focusses on the physical principles of atomic and molecular spectra, as well as the principles of different spectroscopy techniques. Here both the fields of low and high resolution spectroscopy is discussed. Important research applications of spectroscopy lie in the determination of fundamental constants and their possible time variation.
The "real-world" applications discussed in the lecture include topics such as trace gas analysis, optical clocks and lasers in medicine.

    Exercises: 1 hr in groups
      Instructor(s): F. Vewinger
      For term nos.: Master of Physics
      Hours per week: 2+1
      Prerequisites: Basic knowledge in optics, atomic physics and laser physics
      Contents: The lecture gives an overview on different techniques for the generation, amplification and the characterization of ultrashort pulses, i.e. optical pulses with a pulse length below 10 picoseconds. These pulses have gained much interest in recent years, as they allow the time-resolved observation of many different processes, e.g. the vibration of molecules, the dynamics within solids, the breaking and formation of chemical bonds, and very recently, the release of a single electron from an atom. Some of these applications will be discussed in the lecture.
    Another interesting feature of short pulses that will be discussed in the elcture is their enormous bandwidth, which e.g. for an visible pulse of a few femtoseconds length spans a few ten nanometers. This lead to the development of optical frequency combs, which allows the precise measurement of (absolute) frequencies by bridging the gap from the cesium clock transition to the visible/UV regime. The broad bandwidth also allows for the shaping of the pulses, which has become a widely used tool in physical chemistry.

    physics774  Electronics for Physicists
    Tu 10-12, Th 12, HS, HISKP
    Exercises: 1 hr in groups
      Dozent(en): P.-D. Eversheim
      Fachsemester: 5
      Wochenstundenzahl: 3+1
      Erforderliche Vorkenntnisse:  
      Inhalt: Zu den "klassischen" Fähigkeiten eines Experimentalphysikers gehört es, gegebenenfalls die Experimentiergeräte selbst zu bauen, die er benötigt. Mit Blick auf die wachsende elektronisch gestützte Ansteuerung und Auslese der Experimente nehmen Kenntnisse in Elektronik mittlerweile die Rolle einer Schlüsselfertigkeit für einen Experimentalphysiker ein.
    Das Ziel dieser Vorlesung ist es die Studierenden insbesondere anhand beispielgebender Experimente zu befähigen, Lösungskonzepte zu vorgegebenen Problemstellungen zu erarbeiten. Ein Schwerpunkt der Vorlesung besteht darin zu zeigen, dass viele Lösungen bzw. Lösungskonzepte aus anderen Gebieten der Physik bekannt sind (Quantenmechanik, Optik, Mechanik, Akustik, . . .).
    Am Ende der Vorlesung sollte der Studierende:
    i) einen Überblick haben über die gängigsten Bauelemente in der Elektronik.
    ii) ein Bewußtsein besitzen für Probleme im Umgang mit elektronischen Bauelementen und Baugruppen.
    iii) Konzepte verstehen, die eine Analyse und Synthese des dynamischen Verhaltens von Systemen gestatten.

    One of the "classic" abilities of an experimentalist is to build himself the instruments he needs, if necessary. In view of the growing electronics aided control and acquisition of experiments the knowledge of electronics becomes meanwhile a key skill of an experimentalist.
    The intention of this lecture is to enable students by means of exemplary experiments to work out solutions for given problems. A focus of this lecture is to show that many of these solutions are known from other fields of physics (quantum mechanics, optics, mechanics, acoustics, . . .).
    At the end of this lecture, the student should:
    i) have an overview over the most common parts in electronics.
    ii) be concious about the problems of handling electronic parts and assemblies.
    iii) understand the concepts that allow an analysis and synthesis of the dynamic behavior of systems.

    physics652 Seminar on Recent Topics in Nanophotonics and Nonlinear Optics
    Tu 14-16, HS, IAP
    SEXP, WPSEXP
      Instructor(s): S. Linden, D. Haertle, T. Lottermoser
      For term nos.: 5. and higher
      Hours per week: 2
      Prerequisites: Physics courses of the 1.-4. semesters
      Contents: Die Nanophotonik beschäftigt sich mit der Wechselwirkung von Licht mit Materialien, die auf einer (Sub-)Wellenlängen-Skala strukturiert sind. Durch geeignetes Design und durch den Einsatz moderner Fabrikationsmethoden lassen sich Nanostrukturen erstellen, die völlig neuartige optische Eigenschaften besitzen. Zum Beispiel kann ein Photonischer Kristall (eine periodische dielektrische Struktur) wie ein perfekter Spiegel wirken obwohl die zugrunde liegenden dielektrischen Materialien transparent sind. Andere Beispiele sind lokalisierte „Hot Spots“ in plasmonischen Materialien oder photonische Metamaterialien die einen negativen Brechungsindex aufweisen.
    Die nichtlineare Optik beschäftigt sich mit der Wechselwirkung von Licht und Materie bei sehr hohen Lichtintensitäten. Über einen nichtlinear optischen Effekt kann z. B. die Wellenlänge von Laserlicht verändert werden. Dies geschieht besonders effizient mit ultrakurzen Laserpulsen (weil die Spitzenintensität des Lichts sehr hoch ist) und in Kristallen, die keine Inversionssymmetrie besitzen.
    Das Seminar behandelt verschiedene theoretische und experimentelle Aspekte nanophotonischer und nichtlinear optischer Materialien und gibt einen Einblick in den derzeitigen Stand der Forschung.

    -------------------------------------------------

    Nanophotonics deals with the interaction of light with materials which are structured on a (sub-) wavelength scale. Proper design and fabrication of nanostructures can result in optical properties which are not available from the corresponding bulk materials. For instance, a Photonic Crystal, i.e., a periodic dielectric nanostructure, can act as perfect mirror even though the Photonic Crystal’s constituent materials are perfectly transparent. Other examples are localized “hot spots” in plasmonic materials or photonic metamaterials which exhibit a negative index of refraction.
    Nonlinear optics deals with the interaction of light and matter at very large light intensities. For example, a nonlinear optical effect can change the frequency of laser light. This works very efficiently with ultrashort laser pulses, since the peak intensity of these pulses is so large, and with a special category of crystals, which do not possess the inversion symmetry.
    The seminar covers different theoretical and experimental aspects of nanophotonic and nonlinear optical materials and gives an overview on the current status of these fascinating fields of research

    6859  Engineering and characterization of nanostructures by photons, ion beam and nuclear methods
    Blockkurs Mai 2010
      Dozent(en): R. Vianden und Dozenten des ERASMUS Intensive Programme
      Fachsemester: 7+
      Wochenstundenzahl: 2
      Erforderliche Vorkenntnisse: Basic knowledge in nuclear and solid state physics
      Inhalt: This ERASMUS Intensive programme offers a unique opportunity for physicists to work together in a multinational group on methods used in the fascinating world of nanoscale science. The continuous shrinking of device dimensions introduces fundamental challenges with respect to the synthesis, characterization and physical properties of low-dimensional systems. This Erasmus Intensive Programme covers essential and advanced techniques applied to nanostructures. The topics which are discussed include hyperfine interactions, ion-solid interactions, Rutherford backscattering/Channeling, neutron diffraction/reflectivity, muon spin rotation, nuclear resonant scattering of synchrotron radiation, nuclear reaction analysis...

    The level of the courses is such that they are accessible for Master students, but still remain challenging for Post-docs. Typically, two lectures are scheduled in the morning, with tutorials in the afternoon which allow a more thorough discussion and problem solving. These tutorials help the participants to understand the theoretical concepts and apply them to practical situations. A visit to the Ion- and Molecular Beam Laboratory of the Nuclear Solid State Physics Group of the Katholieke Universiteit Leuven will demonstrate the use of several of the techniques discussed in real-time.

    Exercises: 1 hr. by appointment
      Instructor(s): M. Massi
      For term nos.: 5
      Hours per week: 2+1
      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.

    6940 Gravitational lensing
    Di 10-12, HS Astronomie
    Exercises: 1 hr. by appointment
      Instructor(s): P. Schneider, O. Wucknitz
      For term nos.: 8th
      Hours per week: 2 + 1
      Prerequisites:  
      Contents: Aims of the course:

    After learning the basics of gravitational lensing followed by the main applications of strong and weak lensing, the students will acquire knowledge about the theoretical and observational tools and methods, as well as about the current state of the art in lensing research. Strong emphasis lies on weak lensing as a primary tool to study the properties of the dark-matter distribution and the equation of state of dark energy



    Contents of the course:



    The detection of the deflection of light in a gravitational field was not only one of the crucial tests of Einstein's Theory of General Relativity, but has become in the past two decades a highly valuable tool for astronomers and cosmologists. It is ideally suited for studying the mass distribution of distant objects, search for compact objects as a potential constituent of the Galactic dark matter, provide powerful (and cheap) 'natural telescopes' to take a deeper look into the distant Universe, to measure the mass distribution in clusters and on larger spatial scales, and to study the relation between luminous and dark matter in the Universe. Principles and methods are described in detail and the applications will be presented.

    6942  Multiwavelength observations of galaxy clusters
    Mo 15.30-17, MPIfR, HS 0.01
      Instructor(s): T. Reiprich, Y. Zhang, H. Andernach
      For term nos.: 5 or higher
      Hours per week: 2
      Prerequisites: Introductory Astronomy lectures.
      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 intracuster 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, mulitwavelength 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, and active supermassive black holes; cluster weighing methods, Sunyaev-Zeldovich effect, gravitational lensing, radio halos and relics, and the most energetic events in the Universe since the big bang: cluster mergers.
