| Abstract: | The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model
with the Skyrme effective interaction. By providing the analysis of the self-consistent equations at zero temperature, it
is shown that neutron matter with the Skyrme BSk18 effective force undergoes at high densities a phase transition to the state
in which the degeneracy with respect to helicity of neutrons is spontaneously removed. |
