Extension of W-SLDA Toolkit to Fermi-Fermi systems

[Ongoing] Aim is this project is to extend W-SLDA Toolkit towards Fermi-Fermi mixtures, and implementing BSk functional for modeling nuclear matter.

The main goal of the project is to extend the existing HPC W-SLDA (Warsaw - Superfluid Local Density Approximation) code for atomic gases to nuclear systems (proton-neutron matter) and publication of the package. W-SLDA code solves static and dynamic Hartree-Fock-Bogoliubov (HFB) equations, which describe the phenomenon of superconductivity or superfluidity in fermionic systems. Superfluidity/superconductivity is a general feature of many quantum systems at low temperatures. It has been confirmed experimentally in condensed matter systems: in metals and alloys, in liquid helium 3He and 4He; in cold atomic gases; in nuclear systems, including neutron stars; it is also predicted to exist in dense quark matter. Solution of HFB equations in realistic cases is a complex computational problem requiring the usage of supercomputers. Within the project we will add to the modular software the functionality of description of superfluid fermion mixtures in three dimensions (3D). As a result we will be able to describe superfluid nuclear matter within the framework of density functional theory (DFT). The codes will be scalable and able to efficiently use the capabilities of computer systems of a peta scale or greater.

Project is lead by Gabriel Wlazłowski (Warsaw University of Technology, Faculty of Physics).
