Non-positive curvature is a fundamental aspect of geometry appearing in Euclidean spaces, hyperbolic spaces, trees, buildings and many more spaces. We study it with the general but powerful tool of CA
This course introduces the elementary topological concepts and tools that recently spread from condensed matter physics to various quantum and classical wave systems.
Series of lectures covering the use of electron spectroscopy for the study of the electronic and atomic structure of surfaces, nanostructures, and quantum materials. Special attention is given to vari
