We investigate a one-dimensional two-component system in an optical lattice of attractive interactions under a spin- dependent external potential. Based on the density-matrix renormalization group methods, we obtain i...

By using density matrix renormalization group (DMRG) method a model for organic molecule-based ferromagnetic chain is proposed. It is found that the ground states of Undoped and doped systems both exhibit ferrimagne...
Part of the computational work was done on the SGI Origin 3800 and Dawning 3000 supercom-puters at Nanjing University. This work was supported by the National Natural Science Foundation of China (Grant Nos. 20073020 and 20273030).
The empirical valence bond model, solved by the DMRG technique, is applied to the systematical study of the photochemical processes of carotenoids. The polyenes with five up to one hundred of C== C bonds are investiga...
