Our article Spin-polarized vortices with reversed circulation has been published in Phys. Rev. A. The work demonstrates that in spin imbalanced superfluid Fermi gases quantum vortices can have very exotic structures: their cores can rotate in opposite direction from the rest of the fluid.
Our article, titled Local energy density functional for superfluid Fermi gases from effective field theory, has been published in Physical Review A. In this article, we construct SLDAE energy density functional that can be applied to ultracold atoms in BCS-UFG crossover. It is the first paper where we provide a reproducibility pack of W-SLDA Toolkit.
Our article, titled Pairing dynamics and solitonic excitations in collisions of medium-mass, identical nuclei, has been published in Physical Review C. In this paper, we show that pairing field leads to qualitatively different dynamics at the Coulomb barrier like a slower evolution of deformation towards a compact shape or oscillations of pairing field and bears similarity to the pairing Higgs mechanism
Our project Turbulent dynamics in superfluid Fermi systems has been accepted for Pilot Phase realized on LUMI system. The system is expected to start production in 2022 and be then one of the world’s best supercomputers. The Pilot Phase will allow tuning W-SLDA Toolkit towards a new architecture. The project will be executed in collabortion with ICM at University of Warsaw and ELPA Team.
