Double- Chiral Stripe in the - Model with Strong Spin-Charge Coupling
arXiv:1912.03906 · doi:10.7566/JPSJ.89.013702
Abstract
We investigate the stability of multiple- spiral states in - electron systems with the strong spin-charge coupling. By using variational calculations on a square lattice, we find that the double- state with the scalar chirality density wave, which has been studied in the weak spin-charge coupling regime, becomes the ground state even in the strong spin-charge coupling regime by considering the effect of the - hybridization. We also show that the regions where the double- state is stabilized are widely extended for introducing the antiferromagnetic superexchange interaction between nearest-neighbor localized spins.
