Lectures: Summer Semester 2021

The 2021 summer semester runs from April 1st 2021 - September 30th 2021. Owing to COVID-19 pandemic restrictions, several courses will take place wholly or partly online. Lectures will run from April 12th-May 21st and then May 31st-July 24th.

The online platform used by TU Dresden is called Opal. If you do not already have an Opal account, you can register for one here. Once you have access you will be able to view the course materials for at least some of the courses listed here.

General lecture: Tensor Networks

lecturer: Jun. Prof. Hong-Hao Tu
time: Monday, Thursdays 14:50-16:20 starting April 12th
location: Via Zoom
content: 

Tensor networks have wide applications in physics and other scientific disciplines. This course will give an introduction to this rapid evolving field, with an emphasis on the analytical and numerical applications of tensor networks in quantum many-body physics. Various important topics, such as matrix product states, density matrix renormalization group, projected entangled-pair states, and tensor renormalization, will be covered.

General lecture: Network Dynamics and Research on Complex Systems

lecturer:Prof. Marc Timme
time:Wednesdays 11:50-16:20; Thursdays 11:10-12:40 starting April 14th
location:Opal
content:Complex Systems are all around us and most of them are dynamic. Many systems show properties of networks, with many units interacting via intricate topologies. Examples include neural networks in the brain, electric power grids, air transportation networks as well as metabolic or gene regulatory networks in the cell. To understand their collective behavior is far from trivial. Here, we learn methods and tools to grasp why physics thinking may contribute substantially to understand collective structural and dynamical phenomena and the mechanisms underlying them, why some systems may be more complex than others and how to approach analyzing, predicting or even controlling multi-dimensional complex dynamical systems. The course will take place online via Zoom with the option for in-person lectures to be discussed during the course and depending on the situation later in the semester. More details are available in the OPAL course.
