dc.descriptionWe study edge and bulk open-orbit electron states in a quasi-one-dimensional (Q1D) metal subject to a magnetic field. For both types of the states, the energy spectrum near the Fermi energy consists of two terms. One term has a continuous dependence on the momentum along the chains, whereas the other term is quantized discretely. The discrete energy spectrum is mathematically equivalent to the Wannier-Stark energy ladder of a semi-infinite 1D lattice in an effective electric field. We solve the latter problem analytically in the semiclassical approximation and by numerical diagonalization. We show explicitly that equilibrium electric currents vanish both at the edges and in the bulk, so no orbital magnetization is expected in a Q1D metal in a magnetic field.
dc.description7 pages including 3 figures, RevTeX. Ver.2: an appendix and some references are added, the discussion of currents and magnetization is expanded. Ver.3: a section on magnetization in the case where the electron dispersion along the chains is not linear is added
