We held a debate on What is art? in Palau Macaya (Barcelona) on June 14th and 15th, 2023 (in Catalan). A curated extract of the debate can be found here and the entire debate here. A monograph was published in La Maleta de Portbou, Nr. 61 (2023).
My Habilitation (submitted in 2022) sheds some (metaphorical) light on some aspects of quantum theory: on relating the whole to the parts, on quantum magic squares, and on shadows of infinity. The theme from the whole to the parts revolves around eight questions, whose main actresses are non-commutativity, the tensor product, positive elements and complex numbers.
Notes for a 4h crash course into Quantum Information for Physics Master students
An invitation to quantum magic squares and the finding that some cannot be dilated to quantum permutation matrices. Some conceptual consequences are explored in this book chapter.
I tried to share some of the magic of quantum theory, of magic squares and of quantum magic squares here. How beautiful is this sculpture (by Subirachs) at the Sagrada Familia? Not to speak of the Sagrada Familia itself... I should translate the article soon.

Notes for a 1.5 hour crash course on "Computational complexity for physicists", including the solution to a seminar where we showed that the ground state energy problem of the Ising model is NP-hard.
TEDx Talk (June 2021) where I tried to explain in 14 minutes the things that I'm trying to understand myself... PS: the talk was recorded on a stage without an audience :)

An article of "Der Standard" about my work and some personal stuff, with the title "Universal systems: Why is everything so complicated?" That's a good title, I think.
