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…
Ferroelectric phase transition, ionicity condensation, and multicriticality in charge transfer organic complexes
Jun-ichiro Kishine, Tadeusz Luty, Kenji Yonemitsu
To elucidate a novel pressure-temperature phase diagram of the quasi-one-dimensional mixed-stack charge-transfer (CT) complex TTF-CA, we study the quasi-one-dimensional spin-1 Blum…
Interplay of Correlation, Randomness and Dimensionality Effects in Weakly-Coupled Half-Filled Random Hubbard Chains
Jun-ichiro Kishine, Kenji Yonemitsu
We study interplay of electronic correlation, randomness and dimensionality effects in half-filled random Hubbard chains weakly coupled via an interchain one-particle hopping. Base…
Anisotropic suppression of quasiparticle weight in two-dimensional electron system with partially flat Fermi surface: two-loop renormalization-group analysis
Jun-ichiro Kishine, Kenji Yonemitsu
Two-loop renormalization-group analysis for a two-dimensional electron system with a partially flat Fermi surface has been carried out. We found that, {\it irrespective of pairing…
