Early Xmas updates!! Our paper "Quasiparticle and fully self-consistent GW methods: An unbiased analysis using Gaussian orbitals" is now published in @PhysRevB Check it out at: journals.aps.org/prb/abstract/1…
Excited to share our new preprint “Discovering topological phases in gray-Tin.” We uncover known and new topological (and trivial) phases in α-Sn using relativistic GW theory and introduce new topological diagnostics for correlated methods. 🔗 arxiv.org/abs/2511.22740
Attended the @OpenACCorg #OpenHackathon last week, hosted by @TACC! Our team The Self-Energized boosted GPU performance of green-phys.org, our first-principles materials code, by 20% 🚀 Thanks to mentors from @NVIDIA and @LBNLscience for the collaboration!

🎈Asthana group🎈 is looking for motivated PhD students, interested in working at the intersection of quantum computing 💻 and quantum chemistry🧪. theasthanagroup.com
The professor and the pendulums. We know what will happen when one pendulum swings. But two? 'Oxford Mathematicians and their Toys', episode three, starring @jon_ox (and the pendulums).
Delighted to share our new preprint on analysis of different self-consistency schemes in the GW method. If you use quantum chemistry methods to study band structures in materials or ionization potentials in molecules, please checkout our work: arxiv.org/abs/2406.18077
A bit about electronic correlations, and a couple of fun links. nanoscale.blogspot.com/2024/04/electr…
Check out the new multi-author review of “GPAW: An Open Python Package for Electronic Structure Calculations," just published in the Journal of Chemical Physics, which includes a description of some future plans for GPAW. 👀 doi.org/10.1063/5.0182…
It took a while, but my article is now out in the April issue of Scientific American. scientificamerican.com/article/quantu…
we investigate the ability to extract qualitative insight from accurate TPSCI wavefunctions. The local representation makes several qualitative features immediately accessible. Nice work Nicole Braunscheidel and @ArnabBachhar! @VTChemDept arxiv.org/abs/2403.06913
Exciting new developments in relativistic GW methods coming from Zgid group. The challenges in this approach are clearly discussed in this paper by @gaurav_harsha @DominikaZgid @vibinabraham22
Check out our latest preprint with @vibinabraham22 and @DominikaZgid where we show that for quantum systems with heavy elements, capturing the interplay of relativity and electron correlation can be pretty challenging, atleast in Green's function methods. arxiv.org/abs/2403.03961
We are hiring! :) Our growing team at UND is looking for a postdoc researcher to collaborate on exciting quantum computing applications in quantum chemistry. Please reach out to us is you or anyone you know may be interested. Retweets are appreciated! linkedin.com/jobs/view/3818…
