Interplay between fermion condensation and density-wave-instability
Khodel V.A., Shaginyan V.R., Zverev M.V.
It is shown that the phase transition in homogeneous liquids related to the density waves origin is preceded by the fermion condensation. Thus, the fermion condensation may be observed in a low density electron liquid, neutron stars, and in a liquid He3. The three-dimensional (3D) and the two-dimensional (2D) liquids are considered.
