Field-controlled spin current in frustrated spin chains
We study states with spontaneous spin current, emerging in frustrated antiferromagnetic spin-S chains subject to a strong external magnetic field. As a numerical tool, we use a non-Abelian symmetry realization of the density matrix renormalization group. The field dependence of the order parameter...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | We study states with spontaneous spin current, emerging in frustrated antiferromagnetic spin-S chains subject
to a strong external magnetic field. As a numerical tool, we use a non-Abelian symmetry realization of the
density matrix renormalization group. The field dependence of the order parameter and the critical exponents
are presented for zigzag chains with S = 1/2, 1, 3/2, and 2. |
