402-0822-13LIntroduction to IntegrabilityW6 credits2V + 1UN. Beisert
AbstractThis course gives an introduction to the theory of integrable systems, related symmetry algebras and efficients calculational methods.
ObjectiveIntegrable systems are a special class of physical models that can be solved exactly due to an exceptionally large number of symmetries. Examples of integrable models appear in many different areas of physics, including classical mechanics, condensed matter, 2d quantum field theories and lately in string- and gauge theories. They offer a unique opportunity to gain a deeper understanding of generic phenomena in a simplified, exactly solvable setting. In this course we introduce the various notions of integrability in classical mechanics, quantum mechanics and quantum field theory. We discuss efficient methods for solving such models as well as the underlying enhanced symmetries.

402-0898-00LThe Physics of Electroweak Symmetry Breaking
Does not take place this semester.
W6 credits2V + 1Unot available
AbstractThe aim is to understand the need of physics beyond the Standard Model, the basic techniques of model building in theories BSM and the elements of collider physics required to analyze their phenomenological implications. After an introduction to the SM and alternative theories of electroweak symmetry breaking, we will investigate these issues in the context of models with warped extra dimensions.
ObjectiveAfter the course the student should have a good knowledge of some of the most relevant theories beyond the Standard Model and have the techniques to understand those theories that have not been surveyed in the course. He or she should be able to compute the constraints on any model of new physics, its successes explaining current experimental data and its main phenomenological implications at colliders.

AbstractThis course provides a comprehensive introduction to two advanced topics in Quantum Field Theory: Effective Field Theories (EFTs) and Supersymmetry (SUSY).

A phenomenological discussion of the mechanisms of SUSY breaking and the construction of viable supersymmetric extensions of the Standard Model will also be presented.

402-0863-62LDissipation in Quantum SystemsW6 credits2V + 1UR. Chitra
AbstractThe past decade has seen enormous development in nanophysics and qubit technologies for quantum computing. However, the utility of these systems is strongly limited by their coupling to the omnipresent dissipative bath. The fact that the bath typically destroys the coherence of the small open quantum system highlights the importance of understanding the effects of dissipative baths.
ObjectiveThe principal aim of the course is to give the student an introduction to the field and a better appreciation of the impact of noise and dissipation on small quantum systems.
ContentThe course will basically explore the question, "What are the effects of an external environment on the dynamics of a small system ?" We will start with the simplest cases of classical brownian motion and a classical harmonic oscillator connected to a dissipative bath.
We will discuss the importance of fluctuation-dissipation theorems and discuss various physical examples. We will then discuss the quantum analogs of these systems. In particular, there will be a special focus on small open quantum systems, essentially qubits, where we will study the notions of decoherence and relaxation. We will introduce the concept of density matrices and associated methods like quantum master equations. These are particularly useful for studying the dynamics of qubits which are weakly coupled to a dissipative bath.
We will also briefly explore the notions of entanglement entropy and concurrence in such systems.
Some of these questions are linked to more general questions of thermalsation and relaxation of open quantum systems.
Prerequisites / NoticeThe students are expected to have a working knowledge of advanced quantum mechanics. A knowledge of very basic notions of many body theory
will also be useful.
402-0801-66LMechanical MetamaterialsW4 credits2V + 1US. Huber
AbstractA mechanical metamaterial derives its static or dynamic properties not from its microscopic composition but rather through its clever engineering at larger scales. In this course we introduce the basic principles behind the design of modern mechanical metamaterials such as the use of Bragg scattering, local resonances, topological band-structures, and non-linear effects.
ObjectiveThe students should get acquainted with a modern toolbox in the design of mechanical metamaterials. Equipped with the knowledge of the key design principles, the students will be able to choose the appropriate approach to create a metamaterial with a pre-defined functionality either for dynamic applications such as vibration isolation, wave-guiding, or the design of a heat-diode, or static properties such as stress absorption or the design of mechanisms used in robotics.
Content1.) Wave propagation in continuous systems
2.) Wave properties
3.) Discrete systems
4.) Local resonances
5.) Topology by example
6.) Topological classification
7.) Static systems
8.) Non-linear waves
