Boojums on the fermi surface in^{3}HeA and Hamiltonian dynamics of the orbital momentum
Abstract
Boojums (nodes) on the Fermi surface of^{3}HeA lead to peculiar behavior of the intrinsic orbital momentum L in this superfluid. At T=0, L has the form L=( ħ/2 m _{3})l(ρ C _{0}), where C _{0}≈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 that C _{0} is a dynamical invariant, (∂/∂ t) C _{0}=0. The closed system of nonlinear hydrodynamic equations of^{3}HeA at T=0 is constructed in the framework of the Poisson brackets scheme.
