SoSe 21: Stochastics, Correlations and Memory in Physics
Roland Netz
Comments
Theoretical concepts to deal with stochastic, correlation and memory effects in nanoscale- and bio-physics systems (liquids, proteins, organisms) will be introduced and discussed. These concepts will be applied to experiments that probe the motion of particles or organisms, the structure and spectroscopic properties of liquids and chemical or conformational transitions. Concepts will be explained in the lectures, detailed theoretical derivations will be presented in handouts that will be discussed in the tutorial. Analytical theory will be compared with numerical approaches and simulations. The exam will take place in terms of a homework that can be chosen from the different topics covered in class.
