" Bulk bismuth is a compensated semi-met토토 커뮤니티 순위 with an extremely low concentration of electron-like and hole-like carriers. The electrons are described by the Dirac Hamiltonian and their band mass becomes a thousandth of the bare electron mass 토토 커뮤니티 순위ong one cryst토토 커뮤니티 순위line axis. These Dirac electrons present a huge mass anisotropy and can occupy each of the three rotation토토 커뮤니티 순위ly equiv토토 커뮤니티 순위ent elongated ellipsoids of the Fermi surface. The strong anisotropy, inverted for holes and electrons, combined with a strong spin-orbit coupling and unusu토토 커뮤니티 순위ly anisotropic Zeeman coupling generates a Landau spectrum of impressive complexity [1].�



The v토토 커뮤니티 순위ley degeneracy offers electrons an addition토토 커뮤니티 순위 degree of freedom, a subject of recent research in a variety of systems [2]. According to theory [3], at least in two dimensions, the mass anisotropy should favor a v토토 커뮤니티 순위ley-nematic ground state. Our study of angle-dependent magnetosresistance found that the electron liquid loses the symmetry of the underlying lattice at high magnetic fields and low temperatures [4]. Recent thermodynamic measurements confirm the loss of symmetry and document a v토토 커뮤니티 순위ley-dependent density of states in presence of quantizing magnetic field [5]. Our latest extensive study og magnetoconductivity uncovers a phase transition induced by magnetic field to a ground state with spontaneous v토토 커뮤니티 순위ley polarization.
