2025 Summer Semester
During the 2025 summer semester, the Quantum Information & Quantum Many-Body Physics seminar takes place on Thursdays at 11:30 in the Erwin Schrödinger lecture hall (Boltzmanngasse 5, 5th floor). Occasionally, there might be additional seminars out of schedule, or seminars given online, as announced here.

Ilya Kull (University of Vienna)
Density functional theory
Abstract: This will be an introduction to density functional theory. I will try to cover the basics of its theoretical foundation as well as how it is actually used in practice.

Johannes Wladika (University of Vienna)
The Toric Code and XCube Model as stabilizer codes
Abstract: The XCube model can be used as a toy model for studying fracton models. Some characteristic common features of fracton models are well known, such as the existence of immobile excitations, topology dependent ground state degeneracy and the possibility to grow these systems by coupling lower dimensional models to them. The goal of my talk will be to work out those features in the XCube model using the toric code as a 2D model to ease the understanding of the 3D XCube.

Bram Vanhecke (University of Vienna)
Fixed-point differentiation of Tensor Network methods
Abstract: We will discuss recent work being performed in collaboration with Anna Francuz, Paul Brehmer, and researchers from Ghent University where we aim to differentiate a number of widely used tensor network methods: VUMPS, CTM, and "pulling through".
A slow didactical approach will be taken to introduce the key ideas of fixed-point differentiation and in particular VUMPS will be studied in detail.
