Coupled Cluster Treatment of the Alternating Bond Diamond Chain
Jian-Jun Jiang, Yong-Jun Liu, Fei Tang +1
By the analytical coupled cluster method (CCM), we study both the ground state and lowest-lying excited-state properties of the alternating bond diamond chain. The numerical exact…
Phase diagram of a frustrated asymmetric ferromagnetic spin ladder
Lihua Pan, Depeng Zhang, Hsiang-Hsuan Hung +1
We perform a systematic investigation on the ground state of an asymmetric two-leg spin ladder (where exchange couplings of the legs are unequal) with ferromagnetic (FM) nearest-ne…
Coupled cluster treatment of one quasi-one-dimensional coupled spin triangles
Jian-Jun Jiang, Yong-Jun Liu, Fei Tang +1
By using the coupled cluster method (CCM) and the numerical exact diagonalization (ED) method, we investigated the properties of the one quasi-one-dimensional coupled spin triangle…
Analytical and numerical studies of the one-dimensional sawtooth chain
Jian-Jun Jiang, Yong-Jun Liu, Fei Tang +2
By using the analytical coupled cluster method, the numerical exact diagonalization method, and the numerical density matrix renormalization group method, we investigated the prope…
Noncollinear magnetism and half-metallicity in biased bilayer zigzag graphene nanoribbons
Lihua Pan, Jin An, Yong-Jun Liu
We study in this paper the edge polarizations and their consequences for a biased Bernal stacked bilayer graphene nanoribbon with zigzag termination. The magnetic states are classi…
Zigzag graphene nanoribbons without inversion symmetry
Lihua Pan, Jin An, Yong-Jun Liu +1
Graphene on a substrate will suffer an inversion-symmetry-breaking (ISB) lattice potential. Taking electron-electron interaction into account, we study in this paper the possibilit…
The study of spin-spin correlations in quasi-one-dimensional Heisenberg antiferromagnetic clusters
Yong-Jun Liu, Chang-De Gong
For a class of quasi-one-dimensional clusters, by using exact diagonalization, we study the effect of side spins on the spin-spin correlations on chain. Our calculations show that…
Quantum Phase Transitions in Spin-1/2 Frustrated Molecular Cluster: the Numerical Evidence
Yong-Jun Liu, Chang-De Gong
By exact diagonalization, we investigate several spin- real clusters of molecular scale with different shapes. Our calculations show that when the ratio, , o…
