Research interests

• quantum turbulence in superfluid ⁴He
• two-dimensional turbulence
• two-dimensional superfluidity, topological phase transition in superfluid ⁴He
• quantum nature of second sound

I am a principal investigator on a grant "Thermodynamics of quantum liquid investigated through the interaction of nonclassical sounds" awarded by GAČR and a working group 2 co-leader of a COST Action Superfluid Condensates in Astrophysics and Laboratory Experiments​ (SCALES). The projects aim to study two-dimensional turbulence and two-dimensional phase transition in superfluid ⁴He in rotating reference frames using on-chip nanofluidic devices and nonlinear acoustics in superfluid helium, and their possible relations to dynamics of rotating neutron stars.

If you are interested in any of these topics, you might also be interested in summer school organized in Prague thanks to the support from COST.
