Topological Dynamics in the Physical and Biological Sciences

Present research is concerned with numerical modelling of Andreev scattering technique used for detection of quantized vortices in $^3$He-B. The results of numerical analysis of Andreev reflection by three-dimensional turbulent structures are reported. We analyse the Andreev scattering by a dense vortex tangle and calculate the spectral characteristics of the retroreflected beam of thermal excitations. The obtained results are in agreement with experimental observations.
