physics774  Electronics for Physicists Tu 9, Th 1012, HS, HISKP 

Instructor(s):  P.D. Eversheim, C. Honisch  
Prerequisites:  Elektronikpraktikum  
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 and demonstrations 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 conscious 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.  
Literature:  1) The Art of Electronics by Paul Horowitz and Winfield Hill, Cambridge University Press  ”The practitioners bible”  2) Elektronik für Physiker by K.H. Rohe, Teubner Studienbücher  A short review in analogue electronics  3) Laplace Transformation by Murray R.

physics652  Seminar on Precision Measurements with Atoms, Ions, and Molecules Mo 1416, HS, IAP First meeting: 08.10.2018 

Instructor(s):  S. Stellmer  
Prerequisites:  Bachelor education in physics Lectures on Quantum Physics (basic, advanced) would be helpful.  
Contents:  Constructing models, making predictions, and comparing an experiment to theory: this is the essence of research in physics, and this concept has proven to be very successful. This is especially true for precision measurements, which allows us to test our models with a ridiculous uncertainty sometimes approaching 20 digits. This seminar was triggered by a recent determination of the hyperfine structure constant to alpha = 1/137.035999046(27), an improvement by a factor of 5 (Science 360, 191 (2018)). As with most highprecision measurements, this work not only improves a numerical factor, but constrains the parameter ranges available for beyondstandardmodel theories. The seminar has two goals: To provide indepth knowledge about selected key experiments in the field of precision measurements, and to provide practical training in the presentation of a scientific talk. A list of topics will be available on ecampus before the start of the course; further suggestions are welcome. Each topic typically consists of a seminal publication, possibly accompanied by technical papers that explain some of the details. Topics include:
Each topic will be prepared by one or two participants, including literature search and preparation of a 45minute presentation. In each seminar, there will be a presentation, a scientific discussion, and an evaluation of the presentation skills. A short summary of the talk will be written afterwards.  
Literature:  Will be available on ecampus.  
Comments:  Topics will be assigned at the first seminar. Preparation of the talk is a serious amount of work and shall begin as early as possible.
