New publication in Phys. Rev. Research    03-10-2024

In our paper, Phys. Rev. Research 6, L042003 (2024), we have shown that the unitary Fermi gas is a pure quantum many-body system with no classical limit, relevant to the physics of neutron stars, nuclei, cold atoms and condensed matter systems, in which quantum turbulence and non-Markovian dynamics coexist and there is an unexpected slow rate of eigenstate thermalization.

New publication in Eur. Phys. J. A    16-09-2024

A review article about quantum vortices in fermionic superfluids has been published in EPJ A. It presents similarities and differences between vortices in ultracold atomic gases and neutron stars.

New publication in PNAS Nexus    15-04-2024

Our new article devoted to quantum turbulence in Fermi superfluids has been published in PNAS Nexus. For the computation, we have used a LUMI supercomputer.

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,
  • dynamics of superfluid and superconducting systems
  • quantum turbulence
  • phase transitions
  • transport properties

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

LUMI @ CSC’s data center in Kajaani (Finland) - One of the pan-European pre-exascale supercomputers.

Piz Daint Swiss National Supercomputing Centre (Switzerland) - 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
