摘要：

We discuss the energy density of the homogeneous three-dimensional electron gas in a magnetic field in the Hartree-Fock approximation and demonstrate that it exhibits a series of first-order phase transitions when new Landau levels begin to be populated. We investigate consequences of this behavior for Thomas-Fermi type theories of matter in magnetic fields, and show that within this approximation it leads to singular features in electron density profiles.
