Boojums on the fermi surface in3He-A and Hamiltonian dynamics of the orbital momentum

  • G. E. Volovik

Boojums (nodes) on the Fermi surface of3He-A lead to peculiar behavior of the intrinsic orbital momentum L in this superfluid. AtT=0, L has the form L=(ħ/2m3)l(ρ−C0), whereC0≈ρ is the prefactor of the anomalous term in the supercurrent l(l rot l). From the algebra of the hydrodynamical Poisson brackets and from microscopic theory it follows thatC0 is a dynamical invariant, (∂/∂t)C0=0. The closed system of nonlinear hydrodynamic equations of3He-A atT=0 is constructed in the framework of the Poisson brackets scheme.
