New disordered anyon phase of doped graphene zigzag nanoribbon
Young Heon Kim, Hye Jeong Lee, Hyng-Yong Lee +1
We investigate interacting disordered zigzag nanoribbons at low doping, using the Hubbard model to treat electron interactions within the density matrix renormalization group and H…
Resonating Valence Bond States with Trimer Motifs
Hyunyong Lee, Yun-tak Oh, Jung Hoon Han +1
The trimer resonating valence bond (tRVB) state consisting of an equal-weight superposition of trimer coverings on a square lattice is proposed. A model Hamiltonian of the Rokhsar-…
Dynamics of magnon fluid in Dzyaloshinskii-Moriya magnet and its manifestation in magnon-Skyrmion scattering
Yun-Tak Oh, Hyunyong Lee, Jin-Hong Park +1
We construct Holstein-Primakoff Hamiltonian for magnons in arbitrary slowly varying spin background, for a microscopic spin Hamiltonian consisting of ferromagnetic spin exchange,Dz…
Thermal Hall Effect of Spins in a Paramagnet
Hyunyong Lee, Jung Hoon Han, Patrick A. Lee
Theory of Hall transport of spins in a correlated paramagnetic phase is developed. By identifying the thermal Hall current operator in the spin language, which turns out to equal t…
RKKY Interactions in Graphene: Dependence on Disorder and Gate Voltage
Hyunyong Lee, E. R. Mucciolo, Georges Bouzerar +1
We report the dependence of Ruderman-Kittel-Kasuya-Yoshida\,(RKKY) interaction on nonmagmetic disorder and gate voltage in grapheme. First the semiclassical method is employed to r…
