Summer Semester 2019
The 20192020 winter lecture courses run from October 14th  December 21st 2019 and from January 6th  February 8th 2020. The following lectures are offered:
General lecture: Selected Analytic Tools for Quantum Manybody Physics
lecturer:  Prof. Dr. Jan Budich  
time:  Tuesdays 14:5016:20; Wednesdays 14:5016:20  
location:  Tuesdays: REC/B214; Wednesdays: REC/C213  
content:  In this lecture, analytical tools for quantum manybody physics will be theoretically discussed and practically applied. We will cover manybody perturbation theory both in thermal equilibrium and out of equilibrium, as well as methods for the exact solution of correlated lowdimensional systems, such as bosonization. The participants will be guided by accompanying exercises towards independently solving interesting quantum manybody problems using the aforementioned methods.

General lecture: TimeSeries Analysis
lecturer:  Prof. H Kantz (MPIPKS)  
time:  Mondays: 14:5016:20; first lecture October 28th  
location:  MPIPKS Seminar Room 3  
content:  The course will present concepts for the statistical analysis of data with a particular focus on time series data, i.e., data, where the sequence in which they occur contains part of the information. After basic concepts for the characterization of distributions (mean value, standard deviation, higher moments) and some introduction into statistical inference, different aspects of time dependence will be discussed. A central message will be that with a finite amount of data one can never prove anything, and that data analysis therefore is done in term of hypothesis testing and rejection of a null. 
Special lecture: Open Quantum System Dynamics
lecturer:  K. Luoma  
time:  Wednesdays 16:4018:10.  
location:  BZW/A120  
content:  An open quantum system is a quantum system interacting with its surroundings. They are frequently encountered since no quantum system can be consider completely isolated from it's environment. Typically the coupling of the open system to it's external environment leads to decoherence and dissipation which is detrimental to quantum properties such as entanglement. During the last few decades incredible technological advances have made it possible to even experimentally study open quantum system dynamics. In this course we give an introduction to the theory of open quantum systems focusing on stochastic descriptions of the dynamics. These, so called quantum trajectory unravellings of the dynamical map describing the open system dynamics provide additional physical insight to decoherence, continuous quantum measurements etc. We start by first reviewing the basics of Hilbert space quantum mechanics, quantum measurements and stochastic processes. Then we discuss Markovian and nonMarkovian open quantum system dynamics and their stochastic descriptions. Throughout the course we will highlight the concepts with relevant physical examples. 
Special lecture: Concepts of Molecular Modelling
lecturer:  Prof. Dr. G. Cuniberti, Dr. R. Gutierrez  
time:  Tuesdays 09:2010:50.

time:  Wednesdays 14:5016:20  
location:  REC/D016  
content:  The goal of the lecture is to present modern spectroscopic methods with examples (e. g. in the area of magnetism). The methods presented are: photoelectron spectroscopy, xray spectroscopy, neutron scattering, magnetic resonance techniques, Mössbauer spectroscopy, optical spectroscopy, ion beam analysis, mass spectroscopy, tunnel spectroscopy 
Special lecture: Nonequilibrium Field Theory
lecturer:  Francesco Piazza and Steffen Rulands  
time:  Tuesdays 16:4018:10  
location:  MPI PKS Seminar Room 3  
content:  Nonequilibrium systems rely on an influx of energy from the environment to build and maintain complex spatiotemporal structures, prime examples of which are found in biological systems, financial markets and driven quantum systems. In this lecture, we will introduce field theoretic concepts for the description of manyparticle systems far from thermal equilibrium. To begin, we will illustrate under which conditions a stochastic classical description emerges from the microscopic description of open quantum manybody systems. Guided by examples from various fields of science we will then introduce field theoretic methods for nonequilibrium manyparticle systems and discuss critical and universal dynamics in such systems. By highlighting the mathematical similarities between quantum and classical manyparticle systems we will elucidate the close relationship between condensed and living matter systems.
