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…
Coulomb gap in one-dimensional disordered electron systems
Hyun C. Lee
The density of states of one-dimensional disordered electron systems with long range Coulomb interaction is studied in the weak pinning limit. The density of states is found to fol…
Optical conductivity of one-dimensional narrow-gap semiconductors
Hyun C. Lee
The optical conductivities of two one-dimensional narrow-gap semiconductors, anticrossing quantum Hall edge states and carbon nanotubes, are studied using bosonization method. A lo…
The effect of Hund's Coupling on one-dimensional Luttinger Liquids
Hyun C. Lee, S. -R. Eric Yang
Two one-dimensional Luttinger liquid systems coupled by Hund's coupling are studied by the renormalization group and the non-abelian bosonization methods. It is found that the Hund…
Role of Orbitals in Manganese Oxides - Ordering and Fluctuation
R. Maezono, S. Murakami, N. Nagaosa +3
We study the manganese oxides from the viewpoint of the strongly correlated doped Mott insulator. The magnetic ordering and the charge transport are governed by the orbital degrees…
Resonant Raman scattering of quantum wire in strong magnetic field
H. C. Lee
The resonant Raman scattering of a quantum wire in a strong magnetic field is studied, focused on the effect of long range Coulomb interaction and the spin-charge separation. The e…
Electron Correlation and Jahn-Teller Interaction in Manganese Oxides
Naoto Nagaosa, Shuichi Murakami, Hyun Cheol Lee
The interplay between the electron repulsion and the Jahn-Teller electron-phonon interation is studied with a large model for the ferromagnetic state of the mangan…
