Thematic program on “Quantum and Kinetic Problems: Modeling, Analysis, Numerics and Applications” at the National University of Singapore
Xavier Antoine and Yong Zhang were invited in September 2019 at the Thematic Program on Quantum and Kinetic Problems: Modeling, analysis, numerics and applications at the Institute for Mathematical Sciences (IMS), National University of Singapore. They presented our recent efforts (some related to BEC2HPC) concerning the numerical solution to nonlocal…
Meeting at Sichuan University
Xavier Antoine spent 1 month at Sichuan University in August 2019. We worked first with Qinglin Tang and Christophe Geuzaine on a paper on PMLs for the Gross-Pitaevskii equation (GPE). The paper has been submitted at Journal of Computational Physics and is under review. In addition, we worked a lot…
Meeting in Nancy
Qinglin Tang visited Xavier Antoine in Nancy for 10 days in July 2019, while Emmanuel Lorin (Carleton University, Canada) was also in Nancy for collaborating two weeks with us on HPC solutions for quantum mechanical problems as well as on Perfectly Matched Layers (PML).
SciCADE 2019
SciCADE, the International Conference on Scientific Computation and Differential Equations, will be hosted by the University of Innsbruck, Austria, July 22 – 26, 2019. Several members of the BEC2HPC associate team will attend the conference. In particular, Xavier Antoine and Qinglin Tang were invited to organize a mini-symposium on “Computational…
