Ruderman-Kittel-Kasuya-Yosida interactions on a bipartite lattice
J. E. Bunder, Hsiu-Hau Lin
Carrier-mediated exchange coupling, known as Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, plays a fundamental role in itinerant ferromagnetism and has great application potent…
Dynamical symmetry enlargement in metallic zigzag carbon nanotubes
J. E. Bunder, Hsiu-Hau Lin
We revisit correlation effects in doped metallic zigzag carbon nanotubes by using both the one-loop renormalization group and non-perturbative bosonization techniques. Note that, i…
Generic short-range interactions in two-leg ladders
J. E. Bunder, Hsiu-Hau Lin
We derive a Hamiltonian for a two-leg ladder which includes an arbitrary number of charge and spin interactions. To illustrate this Hamiltonian we consider two examples and use a r…
Phase diagrams of the metallic zigzag carbon nanotube
J. E. Bunder, Hsiu-Hau Lin
We investigate a metallic zigzag carbon nanotube by means of a Hubbard model which includes both on-site and nearest neighbour interactions. Assuming weak interactions, a renormali…
