physics612 Accelerator Physics
We, Th 10-12, SR I, HISKP
  Instructor(s): W. Hillert
  Prerequisites: Mechanics, Electrodynamics
  Contents: Die neuere experimentelle Physik basiert zum Teil auf dem Einsatz von Teilchenbeschleunigern, insbesondere im Bereich der Hochenergiephysik, der Materialforschung und der Erforschung der Substruktur der Atomkerne und der Hadronen. Durch die aktuellen wissenschaftlichen Fragestellungen wurden und werden auch weiterhin ständig gesteigerte Herausforderungen an den Betrieb und die Entwicklung von Teilchenbeschleunigern gestellt, was zum Einsatz modernster Technologien aus einer Vielzahl von physikalischen Bereichen führte. Als Beispiele mögen hier der Aufbau des ca. 27 km langen, fast vollständig supraleitenden Large Hadron Colliders (LHC) am CERN / Genf oder des 1 Angström Röntgenlasers (XFEL) am DESY / Hamburg dienen. Im Zuge dieser Entwicklungen und systematischen Untersuchungen der physikalischen Vorgänge in Beschleunigern entstand die Beschleunigerphysik als eigenständiger Fachbereich der angewandten Physik.

Die vorliegende Vorlesung ist eine Einführung in die Beschleunigerphysik. Sie gibt einen Überblick über die verschiedenen Funktionsweisen unterschiedlicher Beschleunigertypen und führt, neben einer physikalischen Behandlung der wichtigsten Subsysteme (Teilchenquellen, Magnete, Hochfrequenzresonatoren), in die transversale und longitudinale Strahldynamik ein.

More recent experimental physics is partly based on the use of particle accelerators, especially in high energy physics, materials research and exploration of the substructure of atomic nuclei and hadrons. Due to the current scientific questions, more and more demanding challenges have been and still are posed to the operation and development of particle accelerators, thus leading to the use of state-of-the-art high technology taken from a multitude of fields in physics. As examples may be cited the construction of the 27 km, almost entirely superconducting Large Hadron Collider (LHC) at CERN / Geneva or the Angström X-ray laser (XFEL) at DESY / Hamburg. In the course of these developments and systematic investigation of the physical processes in particle accelerators, particle accelerator physics emerged as a stand-alone field of applied physics.

The present lecture is meant as an introduction into particle accelerator physics. It provides an overview of the various functional principles of different accelerator types and provides, alongside a physical treatment of the most important subsystems (particle sources, magnets, resonant cavities), an introduction into transversal and longitudinal orbit dynamics.

We plan to replace this course by a module that covers all research areas. Projects in high energy physics will still be possible. For questions, please contact Lecturer E. von Törne, evt@physik.uni-bonn.de.
  Comments: The students join one of the high energy physics groups groups and conduct their own small research project for typically 4 weeks. We recommend to participate in a project during term break (either in spring or summer/ early fall) but projects during the semester are also possible. More information here: http://heplab.physik.uni-bonn.de/
physics719  BCGS intensive week (Statistical and Computational Methods for Experimental Particle Physics at LHC)
  Instructor(s): E. von Törne
  Contents: BCGS Intensive Week, Statistical and Computational Methods for Experimental Particle Physics at LHC
22-26. September, Conference room-II, Physikalisches Institut Bonn

This course will of interest both for students starting their master studies, students who start their master project soon, Ph.D. students from other fields of physics who wish to broaden their horizon. The BCGS intensive week aims at providing a detailed insight of an LHC detector and the experiments that are done with them to address important questions of fundamental physics today.

About half of the course is devoted to hand-on projects. We will offer two topics in parallel:

  • C++ in high energy physics

  • FPGA (hardware-near programming)

What does one need to know to analyse LHC data? While following these lines, particular emphasis is given to
- the scientific and technical requirements of LHC detectors
- the physics of tracking and energy detectors
- the theoretical background of LHC physics (Standard Model + Higgs physics)
- the experimental methods to address these physics questions
Of course, not all topics can be addressed to depth within one week. Thus an effort is made that students will receive an overview and understand the most important mechanisms.
  Comments: see web page http://pi.physik.uni-bonn.de/~evt/teaching/intensiveweek14/
The course is an all-day workshop, starting at September 22 at 9:15. Students from Cologne: There is a regional express train at 8:38 from Köln-Süd that brings you to Bonn in time for the lecture. This train is free with the student ticket.

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 are discussed. The lecture also covers important research applications of spectroscopy, for example 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.
  Literature: Original literature will be given in the lecture. Some useful textbooks include the follwing:

physics742 Ultracold Atomic Gases: Experiment and Theory
Tu 14-16, Th 12-14, HS, IAP
  Instructor(s): M. Köhl, C. Kollath
  Prerequisites: Atomic physics (e.g. phys411); Quantum mechanics (e.g. phys420)
  Contents: Almost hundred years ago, in 1924, A. Einstein and S.N. Bose predicted the
existence of a new state of matter, the so-called Bose-Einstein condensate.
It took 70 years to successfully realize this macroscopic quantum state in
the lab using ultracold atomic gases (Nobel prize 2001). The main challenge
was to achieve cooling to Nanokelvin temperatures, the coolest temperatures
ever reached by mankind.
Nowadays, ultracold gases are exciting systems to study a broad range of
quantum phenomena. These phenomena range from the direct observation of
quantum matter waves and superfluidity over the creation of artificial
crystal structures as analogous to solids, to the realization of complex
quantum phase transitions of interacting atoms, e.g. the formation of a
bosonic Mott-insulator or the BCS superconducting state for Fermions. In
this lecture we will discuss both the experimental and theoretical concepts
of ultra-cold atomic gases.
Outline: Introduction and revision of basic concepts, Fundamentals of atom-
laser interaction
Laser cooling & trapping, Bose-Einstein condensation of atomic gases.
Dynamics of Bose-Einstein condensates
Optical lattices: strongly interacting atomic gases and quantum phase
The crossover of Fermi-gases between a BCS superconducting state and a Bose-
Einstein condensate of molecules.

physics774  Electronics for Physicists
Tu 14-16, Th 12, HS, HISKP
  Instructor(s): P.-D. Eversheim
  Prerequisites: Practical course in electronics
  Contents: One of the "classic" abilities of an experimentalist is to build those instruments himself he needs but can not get otherwise. In this context the knowledge of electronics - in view of the growing electronics aided acquisition and control of experiments - becomes a key skill of an experimentalist.
The intention of this lecture is to enable the students by means of exemplary experiments to work out concepts to solutions for given problems. A focus of this lecture is to show that many of these solutions or concepts to solutions, respectively, are used in other fields of physics too (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
properties of systems.

physics651 Higgs ... and now? - Seminar on current forefront research in particle physics
Do 16-18, Konferenzraum II, PI 1.049, PI
  Instructor(s): I. Brock, K. Desch, J. Dingfelder, N. Wermes
  Prerequisites: Required: Introductory particle physics course Physik511 (Physik V).
Useful: Physics611 (Particle Physics) can be attended in parallel.
  Contents: In 2012, the ATLAS and CMS experiments at CERN announced the discovery of a new particle consistent
with a Higgs boson. However, several further studies are still needed to determine whether all properties of
the observed boson are exactly as predicted in the Standard Model. Will these studies
turn out to be a window to new physics? And is there only one or maybe several Higgs bosons?
In this seminar, we will discuss a variety of analyses (incl. experimental techniques) that will help pin down
the exact nature of the observed boson as well as ongoing and future searches for new physics at the LHC
and future colliders.

Some possible topics for the seminar are:

physics654 Seminar on computational physics:
How to simulate the physical world?
Mo 14-16, SR II, HISKP
  Instructor(s): C. Kollath
  Prerequisites: Quantum Mechanics (no knowledge of programming is required, but you will have to try it.)
  Contents: n the field of physics, computational tools are widely employed as for the analysis of experimental data as well for the description and simulation of physical systems. The motivation to use computational tools is to explore the complex physical world better than otherwise possible with analytical tools. The seminar will cover some of the most commonly used computational methods to simulate physical phenomena. Each student is suppose to understand an algorithm, to apply it to a physical situation mostly from quantum physics and to present the results in a presentation.

The subjects will reach from:
* Time-evolution of Schrödinger equations (e.g. Runge-Kutta and Crank-Nicolson,
split step methods). Physical examples are two-level atoms excited by a light field, a single particle moving in a time-dependent external potential, or the evolution of a Bose-Einstein condensate after an excitation.

* Variational methods and exact solutions for quantum many body systems
The solution of eigenvalue problems lies at the heart of the description of quantum mechanical systems. We will introduce the variational principle and show how this can be applied to describe, e.g., the hydrogen atom. More complicated variational ansaetze as the Gutzwiller ansatz, for bosonic atoms in a periodic potential
can be introduced and the quantum phase transition between a superfluid and a Mott-insulator demonstrated. This is an example of the attractive field of ultracold quantum gases.

* Quantum Monte-Carlo methods
Stochastic methods as the quantum Monte-Carlo method are indispensable to treat systems with a large number of coupled degrees of freedom. Examples are the simulation of quantum gases or classical spin systems. Thereby
we focus the discussion on critical phenomena and the calculation of statistical averages.
