Publicity video about supercomputers (in polish)   05-12-2019

What is a supercomputer? How do scientists use them? What are the most powerful supercomputers today? The answers to these questions can be found in an interview with OtokoClub.

New publication in Phys. Rev. A    16-09-2019

Our article, titled Spin-polarized droplets in the unitary Fermi gas, has been published in Physical Review A. In the article we demonstrate existence of a new type of spatially localized excitation which we dub as ferron.

Our team has been awarded time on Piz Daint    31-03-2019

Our project Investigation of quantum turbulence in strongly interacting Fermi systems submitted within PRACE 18th Call has been awarded. We were granted access to Piz Daint (CSCS) system - presently the fastest European supercomputer.

See here for list of awarded projects

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 INCITE grant.

This year we started new course for students related to supercomputing, titled: Modern computing technologies
