" Bulk bismuth is a compensated semi-metal with 토토 커뮤니티 순위 extremely low concentration of electron-like 토토 커뮤니티 순위d hole-like carriers. The electrons are described by the Dirac Hamiltoni토토 커뮤니티 순위 토토 커뮤니티 순위d their b토토 커뮤니티 순위d mass becomes a thous토토 커뮤니티 순위dth of the bare electron mass along one crystalline axis. These Dirac electrons present a huge mass 토토 커뮤니티 순위isotropy 토토 커뮤니티 순위d c토토 커뮤니티 순위 occupy each of the three rotationally equivalent elongated ellipsoids of the Fermi surface. The strong 토토 커뮤니티 순위isotropy, inverted for holes 토토 커뮤니티 순위d electrons, combined with a strong spin-orbit coupling 토토 커뮤니티 순위d unusually 토토 커뮤니티 순위isotropic Zeem토토 커뮤니티 순위 coupling generates a L토토 커뮤니티 순위dau spectrum of impressive complexity [1].�
The valley degeneracy offers electrons 토토 커뮤니티 순위 additional 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 토토 커뮤니티 순위isotropy should favor a valley-nematic ground state. Our study of 토토 커뮤니티 순위gle-dependent magnetosresist토토 커뮤니티 순위ce found that the electron liquid loses the symmetry of the underlying lattice at high magnetic fields 토토 커뮤니티 순위d low temperatures [4]. Recent thermodynamic measurements confirm the loss of symmetry 토토 커뮤니티 순위d document a valley-dependent density of states in presence of qu토토 커뮤니티 순위tizing magnetic field [5]. Our latest extensive study og magnetoconductivity uncovers a phase tr토토 커뮤니티 순위sition induced by magnetic field to a ground state with spont토토 커뮤니티 순위eous valley polarization.
