Utrecht University Utrecht University in the Netherlands has withdrawn itself from the World University ranking World University Rankings provided by Times Higher Education. As this has generated quite some reactions - praise, questions, some doubts, I want to provide some context. Hence a thread 🧵1/16

Like me, you're a chemist and you've always been a bit scared about Green's functions? Fear no more... Antoine Marie and Abdallah Amar will get you through this formalism with detailed derivations, nice figures, and numerical examples! Laboratoire de Chimie et Physique Quantiques PTEROSOR TREX-EU #compchem

📢'The World Is Your Oyster' is for those who are born in global north countries--don't experience visa bureaucracy & emotional burden that non-white global south scholars do. Citizenship is a privilege that we need to recognize in the academe. 1/n nature.com/articles/d4158…

Stochastic electronic structure methods are useful for simulating large systems. However, they come with some statistical errors. Here, we develop and test methods based on low-rank approximations of Coulomb integrals to accelerate error convergence. arxiv.org/abs/2404.12508

PAPER ALERT! Bexcitonics: Quasiparticle approach to open quantum dynamics tinyurl.com/2e9p7796 In this The Journal of Chemical Physics contribution, Xinxian Chen mapped the open quantum dynamics into that of the system in interaction with a few collective bath excitations or bexcitons!

Now available in JCTC Papers, we combine deterministic (low-rank) and stochastic approaches to accelerate the error convergence in stochastic electronic structure computations! We tested the method for simulating excited states using Green's Functions pubs.acs.org/doi/abs/10.102…

"Among 2800 postdocs working in the US, those holding temporary visas received lower pay and less career support than U.S. citizens and permanent residents", "It’s so common to say, ‘I won’t process your visa paperwork until you finish this paper’” 😑👇🏽 science.org/content/articl…
