The energy spectrum of reconnected vortex loops in He II

Результат исследования: Научные публикации в периодических изданияхстатьярецензирование


The energy spectrum after reconnection of vortex loops at various temperatures of liquid (from a temperature close to absolute zero to T = 1.9 K) has been systematically studied. Initial conditions were varied at each temperature: the vortex loops were initially located in planes, the angle between which varied from 0 to π/2. A statistical approach was used to find the spectrum: the second-order longitudinal structure function of the velocity was calculated. In all the cases considered, the spectra E(k) ∝ (k)-3/2 were obtained, which are typical of a smooth vortex ring.
