Electron liquid in a superstrong magnetic field
Keldysh L.V., Onishchenko T.A.
It is shown that the energy of an electron-hole plasma in ultrastrong magnetic field has, as a function of the density, a minimum in the strong-compression region. The equilibrium density is Ð0~{ÅîÁï1/^Ó)ÇÐÁ^Ç, and the energy per particle is given by å/rio~ — n01/4e 2ao~1/4, where Η is the field intensity and Oo is the effective Bohr radius.
