Supercomputing

Most of our studies require usage of top-tier supercomputing systems. Machines that we have or we had access include:

Piz Daint
Summit
Tsubame 3.0
Okeanos
Piz Daint @  Swiss National Supercomputing Centre (Switzerland) - presently the fastest European computing system. Access is granted thanks to PRACE. Summit @ Oak Ridge National Laboratory (USA) - presently the fastest world computing system. Access is granted thanks to INCITE grant. Tsubame3.0 @ Global Scientific Information and Computing Center, Tokyo Institute of Technology (Japan) Okeanos @ Interdisciplinary Centre for Mathematical and Computational Modelling (Poland)

Using this extraordinary technology we are able to study with a fgreat details equilibrium and non equilibrium processes in strongly correlated quantum systems: atomic nuclei and quantum gases. Our codes based on Density Functional Theory are capable of solving millions of coupled non-linear, time-dependent partial differential equations with high accuracy, allowing for studies of a real-time 3D superfluid dynamics without any symmetry restrictions. It makes them the most advanced simulation capability of its kind in the world, suitable to describe processes of nuclear fission/fusion or quantum turbulence.
