I am currently on full-time parental leave (please don't send me review requests!). Previously, I was a researcher in the quantum information theory group of Renato Renner at ETH Zurich. I did my PhD in Jens Eisert's group at FU Berlin. I am interested both in abstract quantum information theory and in using ideas and tools from (quantum) information theory to obtain interesting and rigorous results in other areas, in particular in the theory of quantum many-body systems and statistical physics.
I am always happy to receive e-mails regarding my work, so please feel invited to send any questions or comments. My CV is available on request.
Most of my publications can be found on the arXiv.
- APS Physics selected our paper on (re-)discovering physical concepts using neural networks as one of the highlights of the year 2020.
- APS Physics published a viewpoint featuring our paper on equilibration in entanglement-ergodic quantum systems. Pro-physik.de published a similar piece (in German).
- APS Physics published a viewpoint on our paper on using neural networks to (re-)discover physical concepts in simply toy models. NZZ also published an article in German. Before that, Nature published an article in the News section. This piece was followed up by a piece in unite.ai and at bigthink.com. MIT Technology Review previously published a similar piece. Nautilus published a piece criticizing the reporting about our and other papers.
- The IQOQI Vienna issued a press release on our paper "von Neumann entropy from unitarity" published in PRL. In the paper we formulate the "catalytic entropy conjecture", which is now problem 45 on the list of open problems inquantum information theory. Update: In this preprint I provide an affirmative solution to the catalytic entropy conjecture.
- Our paper on "Statistical Ensembles without Typicality" published in Nature Communications was featured at ProPhysik (German). The FU Berlin also issued a press release (German).
