| 中文摘要 | in this paper we report the applicability of the density matrix renormalization group (dmrg) approach to the cylindrical single wall carbon nanotube (swcn) for the purpose of its correlation effect. by applying the dmrg approach to the t+u+v model, with t and v being the hopping and coulomb energies between the nearest neighboring sites, respectively, and u the on-site coulomb energy, we calculate the phase diagram for the swcn with chiral numbers (n(1)=3, n(2)=2), which reflects the competition between the correlation energy u and v. within reasonable parameter ranges, we investigate possible correlated ground states, the lowest excitations, and the corresponding correlation functions in which the connection with the excitonic insulator is particularly addressed. |
