Recent news and media coverage
- Our work on embezzlement of entanglement from quantum fields was accepted in PRL.
- On November 18th 2024, I was invited to give the Zurich Theoretical Physics Colloquium with an overview talk on entanglement in the thermodynamic limit.
- Niklas Galke presented our joint work on sufficiency of Rényi divergences (31) at TQC 2024. A recoding can be watched here.
- I presented our work on the classification of von Neumanna algebras and embezzlement of entanglement at the International Congress of Mathematical Physics (ICMP) 2024 in Strasbourg.
- Our Review of Modern Physics on catalysis in quantum information theory (32) is finally out and featured in APS Physics.
- IEEE Transactions in Information Theory published our work on sufficiency of Rényi divergences.
- Our long plenary talk at QIP '24 on embezzlement of entanglement can be watched here. An updated version of the talk by Alexander Stottmeister can also be seen in the IAMP online seminar.
- Nature Communications published our demonstration of reviving product states in the paradigmatic model for many-body localization.
- Quantum published my proof of the exact catalytic entropy conjecture.
- PRL published my proof of the approximate catalytic entropy conjecture.
- 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. Neue Züricher Zeitung 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.
