iiinova — where your digital self keeps evolving

Writing software is a big part of experimental physics. Even a moderately complex experiment involves several instruments that need to talk and stay synchronised. To solve that problem I released mesoscopy, a modular experiment runner written with python and Qt. julienbarrier.eu/blog/2026/10...

Welcome to Dr. Julien Barrier! The main quest in Julien's group is to combine the nanofabrication of graphene structures, nanophotonic probes and quantum transport at ultra-low temperatures to induce, control and explore strong electron interactions in one- and two-dimensional systems.

In the next edition of #CondensedMatterPioneers we would like to highlight the career of Pierre-Gilles de Gennes (1932-2007), a French physicist renowned for his extensive contributions to condensed matter physics, particularly in the study of soft matter.🧵

I’m excited to be invited to the GEFES meeting (Condensed Matter Physics group of the Royal Society of Spain). I’ll be sharing my work on Coulomb screening in twisted graphene on Thursday afternoon, and I’m looking forward to catch up with everyone

There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research. A Place of Joy.

‘A place of joy’: why scientists are joining the rush to Bluesky
Researchers say the social-media platform — an alternative to X — offers more control over the content they see and the people they engage with.: https://www.nature.com/articles/d41586-024-03784-6

Prof. Dorothy Bishop has resigned from the Royal Society over Elon Musk's fellowship. Women make up only around 12% of Royal Society fellows, and now they have lost a good one for the sake of keeping a man who is responsible for widely spreading misinformation about science.

This is obviously a (funny) joke, but I have seen so many over-achieving students fly through University with very high marks and then crash when they started their PhD because they had no idea how to deal with a question nobody know the answer to.

My paper "One-dimensional proximity superconductivity in the quantum Hall regime" has been published in Nature! Here we introduce a new 1D electronic system in which we induce superconductivity. Check it out at rdcu.be/dFD1t

One-dimensional proximity superconductivity in the quantum Hall regime

Nature - We show that domain walls in minimally twisted bilayer graphene support exceptionally robust proximity superconductivity in the quantum Hall regime.
