Abstract  In condensed matter physics, “ultrafast” refers to dynamics on the picosecond and femtosecond time scales, the time scales where atoms vibrate and electronic spins flip. Measuring realtime dynamics on these time scales is key to understanding materials in nonequilibrium states. This course offers an overview and understanding of the methods used to accomplish this in modern research laboratories.  
Objective  The goal of the course is to enable students to identify and evaluate experimental methods to manipulate and measure the electronic, magnetic and structural properties of solids on the fastest possible time scales. This offers new fundamental insights on the couplings that bind solidstate systems together. It also opens the door to new technological applications in data storage and processing involving metastable states that can be reached only by driving systems far from equilibrium. This course offers an overview of ultrafast methods as applied to condensed matter physics. Students will learn which methods are appropriate for studying relevant scientific questions, and will be able to describe their relative advantages and limitations.

Abstract  This course covers the physics of trapped ions at the quantum level described as harmonic oscillators coupled to spin systems, for which the 2012 Nobel prize was awarded. Trappedion systems have achieved an extraordinary level of control and provide leading technologies for quantum information processing and quantum metrology.  
Objective  The objective is to provide a basis for understanding the wide range of research currently being performed with trapped ion systems: fundamental quantum mechanics with spinspring systems, quantum information processing and quantum metrology. During the course students would expect to gain an understanding of the current frontier of research in these areas, and the challenges which must be overcome to make further advances. This should provide a solid background for tackling recently published research in these fields, including experimental realisations of quantum information processing using trapped ions.

In all experimental settings the role of decoherence and the quantumclassical transition is of great importance, and this will therefore form one of the key components of the course. The topics of the course were cited in the Nobel prize which was awarded to David Wineland in 2012. Topics which will be covered include:  Fundamental working principles of ion traps and modern trap geometries, quantum description of motion of trapped ions  Electronic structure of atomic ions, manipulation of the electronic state, Rabi and Ramseytechniques, principle of an atomic clock  Quantum description of the coupling of electronic and motional degrees of freedom  Laser cooling  Quantum state engineering of coherent, squeezed, cat, grid and entangled states  Trapped ion quantum information processing basics and scaling, current challenges  Quantum metrology with trapped ions: quantum logic spectroscopy, optical clocks, search for physics beyond the standard model using highprecision spectroscopy

Abstract  In this course, we will review the status of physics with exotic atoms including the new exciting advances such as antihydrogen 1S2S spectroscopy and measurements of the hyperfine splitting and the puzzling results of the muonichydrogen experiment for the determination of the proton charge radius.  
Objective  The course will give an introduction on the physics of exotic atoms covering both theoretical and experimental aspects. The focus will be set on the systems which are currently a subject of research in Switzerland: positronium at ETHZ, antihydrogen at CERN and muonium, muonicH and muonicHe at PSI. The course will enable the students to follow recent publications in this field.  
Content  Review of the theory of hydrogen and hydrogenlike atoms Interaction of atoms with radiation Hyperfine splitting theory and experiments: Positronium (Ps), Muonium (Mu) and antihydrogen (Hbar) High precision spectroscopy: Ps, Mu and Hbar Lamb shift in muonicH and muonicHe the proton radius puzzle Weak and strong interaction tests with exotic atoms Antimatter and gravitation Applications of antimatter

402073800L  Statistical Methods and Analysis Techniques in Experimental Physics  W  10 credits  5G  M. Donegà  
Abstract  This lecture gives an introduction to the statistical methods and the various analysis techniques applied in experimental particle physics. The exercises treat problems of general statistical topics; they also include handson analysis projects, where students perform independent analyses on their computer, based on real data from actual particle physics experiments.  
Objective  Students will learn the most important statistical methods used in experimental particle physics. They will acquire the necessary skills to analyse large data records in a statistically correct manner. Learning how to present scientific results in a professional manner and how to discuss them.  
Content  Topics include:  modern methods of statistical data analysis  probability distributions, error analysis, simulation methos, hypothesis testing, confidence intervals, setting limits and introduction to multivariate methods.  most examples are taken from particle physics. Methodology:  lectures about the statistical topics;  common discussions of examples;  exercises: specific exercises to practise the topics of the lectures;  all students perform statistical calculations on (their) computers;  students complete a full data analysis in teams (of two) over the second half of the course, using real data taken from particle physics experiments;  at the end of the course, the students present their analysis results in a scientific presentation;  all students are directly tutored by assistants in the classroom.  
Lecture notes   Copies of all lectures are available on the website of the course.  A scriptum of the lectures is also available to all students of the course.

402070300L  Phenomenology of Physics Beyond the Standard Model  W  6 credits  2V + 1U  M. Spira, A. de Cosa  
Abstract  After a short introduction to the theoretical foundations and experimental tests of the standard model, grand unified theories, supersymmetry, leptoquarks, and hidden valley models will be treated among other topics. Thereby the phenomenological aspects, i.e. the search for new particles and interactions at existing and future particle accelerators will play a significant role.  
Objective  The goal of the lecture is the introduction into several theoretical concepts that provide solutions for the open questions of the Standard Model of particle physics and thus lead to physics beyond the Standard Model. Besides the theoretical concepts the phenomenological aspects are discussed, i.e. the search for new particles and interactions at the existing and future particle accelerators.
