Normal Fermi liquid in a superfluid 3He-A at T=0 and the anomalous current
Volovik G. E.
In the presence of a texture in the field of an orbital vector 1, the subsystem of a superfluid 3He-A is a normal Fermi liquid which consists of particles at the zero Landau level in an effective "magnetic" field produced by the texture. In the ground state, the Fermi liquid carries an anomalous current (parallel to the magnetic field)—(#/2m3) pi (1 curl 1) which plays a decisive role in the dynamics of3He-^atr=0.
