Our team has been granted access to LUMI    10-09-2020

Our project Supersolidity in ultracold Fermi gashas been accepted for Pilot Phase realized on LUMI system. The system is expected to start production in 2022 and being then one of the world’s best supercomputers. The Pilot Phase will allow tuning W-SLDA Toolkit towards a new architecture.

New publication in Phys. Rev. A    02-09-2021

Our article, titled Dynamics of spin-polarized impurity in ultracold Fermi gas, has been published in Physical Review A. Here, we investigate the dynamical properties of polarized droplets, called ferrons, like their effective mass or stability properties with respect to the flow.

Presently studied problems

My scientific interests concern theoretical study of various phenomena in strongly correlated many-body Fermi systems (nuclear systems, ultra-cold atoms), in particular: 

  • superconducting/superfluid properties
  • thermodynamic equilibrium and non-equilibrium properties,
  • phase transitions
  • transport properties
  • dynamics of superfluid and superconducting systems

Quantum turbulence

Under some conditions dynamics of quantum vortices may become chaotic and leads to a new type of behavior called quantum turbulence. Aim of these studies is to better understand  the dynamics in strongly interacting Fermi systems.

Quantum vortices in neutron stars

Despite 40 years of studies of neutron stars, detailed mechanism for glitches remains a puzzle. Together with researchers from CAMK we try to construct reliable model of this mysterious astrophysical phenomena.

Superfluid effects in nuclear reactions

Recently, we have reported a novel role of pairing in low-energy heavy ion reactions at energies above the Coulomb barrier, which may have a detectable impact on reaction outcomes. The effect is under further investigation.

See our paper with simple explanation of the effect

... and Supercomputing

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

Check Top500 for present ranking of supercomputers

Piz Daint Swiss National Supercomputing Centre (Switzerland) - presently the fastest European computing system. Access is granted thanks to PRACE.

See article at CSCS webpage

Summit @ Oak Ridge National Laboratory (USA) - presently the fastest world computing system. Access is granted thanks to ASCR program.

My group develops W-SLDA Toolkit: a self-consistent solver of mathematical problems which have structure formally equivalent to Bogoliubov-de Gennes equations. The toolkit is designed to solve problems related to fermnic superfluidity
