Correlation effects for semiconducting single wall carbon nanotube: a density matrix renormalization group study
Fei Ye, Bing-Shen Wang, JiZhong Lou +1
In this paper, we report the applicability of the density matrix renormalization group(DMRG) approach to the cylindrical single wall carbon nanotube (SWCN) for purpose of its corre…
Aharonov-Bohm Oscillation and Chirality Effect in Optical Activity of Single Wall Carbon Nanotubes
Fei Ye, Bing-Shen Wang, Zhao-Bin Su
We study the Aharonov-Bohm effect in the optical phenomena of single wall carbon nanotubes (SWCN) and also their chirality dependence. Specially, we consider the natural optical ac…
Electronic and Structural Properties of C Molecule
Xiaoqing Yu, Congjun Wu, Chui-lin Wang +1
The extended SSH model and Bogoliubov-de Gennes(BdeG) formalism are applied to investigate the electronic properties and stable lattice configurations of C. We focus the pro…
Schwinger boson mean field theory of the Heisenberg Ferrimagnetic Spin Chain
Congjun Wu, Bin Chen, Xi Dai +2
The Schwinger boson mean field theory is applied to the quantum ferrimagnetic Heisenberg chain. There is a ferrimagnetic long range order in the ground state. We observe two branch…
The Effective Theory of Hole Doped Spin-1 Chain
Xi Dai, Bin Chen, Zhao-Bin Su
An effective theory for the hole doped spin-1 antiferromagnetic chain is proposed in this paper. The two branches of low energy quasipaticle excitation is obtained by the diagrammi…
Comparative Study of the Insulator-Hall Liquid-Insulator Transitions: Composite Boson Picture vs Composite Fermion Picture
Wenjun Zheng, Yue Yu, Zhaobin Su
Based on a newly advanced phenomenological understanding of the high-field insulator- Hall liquid transition in a composite fermion picture, we extend its composite boson counterpa…
