中文摘要We propose a model of spin-polarized current state for electrons in bilayer graphene. The model resolves the puzzles as revealed by experiments that (a) the energy gap E-gap of the insulating ground state at the charge neutrality point (CNP) can be closed by a perpendicular electric field of either polarity, (b) E-gap increases significantly with increasing the magnetic field B, (c) the particle-hole spectrum is asymmetric in the presence of B, (d) there is a peak structure in the electric conductivity at small B at the CNP, and (e) there are quantum Hall states stemming from lifting of degeneracy in the lowest Landau level. The model predicts that the ground state of the system close to the CNP is a ferrimagnet at finite B and the Hall current is spin polarized.
