Sign reversals of the quantum Hall effect and helicoidal magnetic-field-induced spin-density waves in quasi-one-dimensional organic conductors
N. Dupuis, Victor M. Yakovenko
We study the effect of umklapp scattering on the magnetic-field-induced spin-density-wave phases, which are experimentally observed in the quasi-one-dimensional organic conductors…
Edge and bulk electron states in a quasi-one-dimensional metal in a magnetic field: The semi-infinite Wannier-Stark ladder
Victor M. Yakovenko, Hsi-Sheng Goan
We 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 Fer…
Phenomenological interpretations of the ac Hall effect in the normal state of YBa2Cu3O7
Anatoley T. Zheleznyak, Victor M. Yakovenko, H. D. Drew +1
Ac and dc magnetotransport data in the normal state of YBa2Cu3O7 are analyzed within Fermi-liquid and non-Fermi-liquid models. In the Fermi-liquid analysis we use the Fermi surface…
Hopf Term for a Two-Dimensional Electron Gas
G. E. Volovik, V. M. Yakovenko
In this Comment on the paper by W. Apel and Yu. A. Bychkov, cond-mat/9610040 and Phys. Rev. Lett. 78, 2188 (1997), we draw attention to our prior microscopic derivations of the Hop…
Spin, Statistics and Charge of Solitons in (2+1)-Dimensional Theories
Victor M. Yakovenko
General topologically invariant microscopical expressions for quantum numbers of particle-like solitons ("skyrmions") are derived for a class of (2+1)D models. Skyrmions are either…
