Hidden Galilean symmetry, conservation laws and emergence of spin current in the soliton sector of chiral helimagnet
I. G. Bostrem, J. Kishine, R. V. Lavrov +1
Motivated by the spin current problem in chiral helimagnet, we rigorously elucidated the hidden Galilean invariance in the chiral XY model under the magnetic field. The Lie group a…
Theory of spin current in chiral helimagnet
I. G. Bostrem, Jun-ichiro Kishine, A. S. Ovchinnikov
We give detailed description of the transport spin current in the chiral helimagnet. Under the static magnetic field applied perpendicular to the helical axis, the magnetic kink cr…
Transport magnetic currents driven by moving kink crystal in chiral helimagnets
I. G. Bostrem, Jun-ichiro Kishine, A. S. Ovchinnikov
We show that the bulk transport magnetic current is generated by the moving magnetic kink crystal (chiral soliton lattice) formed in the chiral helimagnet under the static magnetic…
Quantum dissipation theory of slow magnetic relaxation mediated by domain-wall motion in one-dimensional chain compound [Mn(hfac)_{2}BNO_{H}}]
A. S. Ovchinnikov, I. G. Bostrem, V. E. Sinitsyn +3
Based on a quantum dissipation theory of open systems, we present a theoretical study of slow dynamics of magnetization for the ordered state of the new molecule-based magnetic com…
Real-space renormalization group study of the anisotropic antiferromagnetic Heisenberg model of spin S=1 on a honeycomb lattice
A. S. Boyarchenkov, A. S. Ovchinnikov, I. G. Bostrem +3
The real-space RG approach is applied to study critical temperatures of system consisting of interacting spin chains of spin S=1 with an inner antiferromagnetic exchange which form…
Topological stripelike coreless textures with inner incommensurability in two-dimensional Heisenberg antiferromagnet
E. V. Sinitsyn, I. G. Bostrem, A. S. Ovchinnikov
For two-dimensional Heisenberg antiferromagnet we present an analysis of topological coreless excitations having a stripe form. These textures are characterized by singularities at…
