Antiferromagnetic Heisenberg ladders in a staggered magnetic field
Jize Zhao, Xiaoqun Wang, Tao Xiang +4
We study the low-energy excitations of the spin-1/2 antiferromagnetic Heisenberg chain and -leg (=2, 3, 4) ladders in a staggered magnetic field . We show that ind…

Midgap States in Antiferromagnetic Heisenberg Chains with A Staggered Field
Jizhong Lou, Changfeng Chen, Jize Zhao +4
We study low-energy excitations in antiferromagnetic Heisenberg chains with a staggered field which splits the spectrum into a longitudinal and a transverse branch. Bound states ar…

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…
