25 March: Ian has a new paper out in which he analyzes the relative positions of half-sided modular inclusions of standard subspaces in a common environment space, a situation commonly encountered in quantum field theory.
From 1 April, Christiaan van de Ven will join us as a PostDoc – Welcome, Chris!

3 February 2025: In the summer term, I will offer a lecture on algebraic quantum field theory and a seminar on Tomita-Takesaki modular theory for students who want to learn more about operator algebras and mathematical physics. See this website for current and upcoming teaching.
31 January 2025: Today Justin Gassner successfully defended his MSc thesis “A Local Modular Quantum Energy Inequality for the Scalar Free Field”.Congratulations! 🥳
13-17 January 2025: This week Ian will speak at RSME’s 7th Congress of Young Researchers in Bilbao and Ricardo and I will go to Quantum groups, tensor categories and quantum field theory in Oslo.
7-9 November 2024: The 49th edition of the Local Quantum Physics Workshop series takes place in Erlangen. Its schedule and the link to registration can be found here.

01 October: From today Ricardo Correa da Silva works as a substitute professor in our department. He will give independent lectures and seminars in the upcoming terms.
30 September – 4 October: I will attend the workshop Operator Algebras in High Energy Physics at Nordita, Stockholm.
16 September 2024: Today Johannes Große successfully defended his MSc thesis “KMS States on Crossed Products by Finite Groups — Twisted KMS Functionals and Operator-Valued States”. Congratulations! 🥳
16 September 2024: In the winter term, we will offer a lecture on operator algebras and operator theory (“functional analysis 2”) that will introduce these subjects to interested students familiar with a typical first course in functional analysis. There are also still some places available in the seminar on functional analysis (Querschnittsmodulseminar). See this website for current and upcoming teaching.
2 August 2024: The final version of our crossing symmetry paper is available at https://arxiv.org/abs/2402.15763. In this paper we begin a systematic study of crossing symmetry from the point of view of modular theory. It will be published in a memorial volume of Reviews in Mathematical Physics dedicated to the memory of Huzihiro Araki.
24-26 July 2024: I will be attending the workshop Exactly Solvable Models at the ESI Vienna held in honour of Harald Grosse.
15-26 July 2024: These two weeks Luca Giorgetti from the University Tor Vergata in Rome will visit us and give a talk on Crossing Symmetry and Fourier Transforms on July 22.
1-6 July 2024: This week Fernando Lledó from the University Carlos III in Madrid will visit us and give a talk on finite-dimensional approximations in C*-algebras on Thursday.
