Abstract
Turbulent excitations have been observed in superfluid liquid helium, a Bose Einstein system, that obeys the Kolmogoroc \(\frac{5}{3}\) scaling law for its energy spectrum. In recent joint work with Kouskik Ray of IACS we show how by regarding superfluid helium as a Bose Einstein quantum field theory with local 3 dimensional scale invariance leads to the Kolmogorov scaling law observed. In order to get local 3 dimensional scale invariance geometrical methods are needed, while in order to derive the observed turbulence scaling law the Bose Einstein condensation description of superfluid helium and Zakharov’s weak wave turbulence method are used.
