Influences of an impurity on the transport properties of one-dimensional antisymmetric spin filter
Jaeshin Park, Hyun C. Lee
The influences of an impurity on the spin and the charge transport of one-dimensional antisymmetric spin filter are investigated using bosonization and Keldysh formulation and the…

Effect of Hund coupling in the one-dimensional SU(4) Hubbard model
Hyun C. Lee, Patrick Azaria, Edouard Boulat
The one-dimensional SU(4) Hubbard model perturbed by Hund coupling is studied, away from half-filling, by means of renormalization group and bosonization methods. A spectral gap is…
