Spontaneous breaking of axial symmetry in k-vortices in superfluid 3He-B
Volovik G. E., Salomaa M. M.
A new, axially asymmetric state of a broken-parity vortex in 3He~B has been found. At low pressures, this state has an energy lower than that of an axisymmetric state. Only a first-order phase transition can occur between these two states. The properties of a rotating liquid, which are associated with the breaking of axial symmetry in a vortex, are discussed.
