Description: The objective of this class is to introduce students to ab initio methods for electronic-structure calculations based on density-functional theory (DFT). The topics will be approached from the viewpoint of condensed-matter physics. In the first part of the semester, theoretical lectures will be accompanied by exercise sessions. The last few weeks of the term will be exclusively dedicated to hand-on tutorials. At the end of this course, participants are expected to be familiar with the theoretical foundation of DFT, to be able to perform a DFT calculation with good control of the given approximations, and to know how to interpret the outcoming results.
The course as a whole (theoretical lectures, exercises, and hands-on tutorials) can be offered in presence, in digital form, or even in a mixed regime, depending on the circumstances and on the students’ needs.
The course is addressed to Master’s students in theoretical physics. However, Master’s students in experimental physics, doctoral students in all specializations, and Bachelor’s students who are interested in (computational) electronic-structure theory are very welcome to participate. Good knowledge of quantum mechanics is the only prerequisite to attend this class.

Zunächst wird das Bose-Hubbard-Dimer als ein einfaches Modellsystem für quantenmechanische Vielteilchensysteme vorgestellt. Die Drehimpulsdarstellung dieses Modells wird diskutiert und sein Spektrum für kleine und große Teilchenzahlen numerisch berechnet. Dann wird der in diesem Modell auftretende "self trapping-Übergang" analytisch und numerisch untersucht und die Güte der mean field-Approximation mit Hilfe exakter numerischer Rechnungen überprüft.
Im zweiten Teil der Veranstaltung wird das Modell um einen zeitperiodischen Antrieb erweitert, so dass die nichtlinearen mean field-Gleichungen chaotische Lösungen besitzen. Die Signaturen der Lösungen der linearen Schrödingergleichung, die dieses Verhalten bedingen, werden numerisch untersucht und mit Hilfe von Husimi-Darstellungen visualisiert.

5.04.4883 - Chaos, catastrophes, and fractals
- Dr. rer. nat. Michael Sinhuber
Monday: 10:15 - 11:45, weekly (from 17/10/22)
The goal of this lecture is to get acquainted with prevalent concepts for dynamic systems. Particular emphasis lies on the interpretation of certain non-linear deterministic systems with respect to their fixed points (stationary or equilibrium solutions) as well as their sensitivity with respect to initial conditions (characterization via Lyapunov exponents). The evolution of fixed point leads to the catastrophe theory. The time evolution of non-stationary and non-linear system leads to chaos. Different routes to chaotic regimes will be discussed and put into the context of applications such as coupled generators in wind energy systems. The concept of fractal measures will be discussed at selected examples (Cantor set, Koch curves, etc.), which serves for the characterisation of chaotic attractors but also for fractal geometries like boarder lines, surfaces, turbulence or boundaries of basins of attraction.
Ziel dieser Vorlesung ist es, gängige Konzepte für dynamische Systeme kennenzulernen. Ein besonderer Schwerpunkt liegt auf der Interpretation bestimmter nichtlinearer deterministischer Systeme hinsichtlich ihrer Fixpunkte (stationäre oder Gleichgewichtslösungen) sowie ihrer Empfindlichkeit gegenüber Anfangsbedingungen (Charakterisierung über Ljapunov-Exponenten). Die Entwicklung von Fixpunkten führt zur Katastrophentheorie. Die zeitliche Entwicklung von nicht-stationären und nicht-linearen Systemen führt zum Chaos. Verschiedene Wege zu chaotischen Regimen werden diskutiert und in den Kontext von Anwendungen gestellt (z. B. gekoppelte Generatoren in Windenergieanlagen). An ausgewählten Beispielen (Cantor-Menge, Koch-Kurven, etc.) wird das Konzept der fraktalen Maße diskutiert, das zur Charakterisierung von chaotischen Attraktoren, aber auch von fraktalen Geometrien wie Grenzlinien, Flächen, Turbulenzen oder Grenzen von Anziehungsgebieten dient.
