| 中文摘要 | We extend a Quantum Monte Carlo (QMC) algorithm to the Hubbard model containing bond-dependent off-diagonal hoppings, which describes the manganites and other similar systems, such as systems with spin-flip hoppings. To show correctness of this extension, we detect two simple examples of one-dimensional chains. The first one is half-filled and the hopping matrixes between arbitrary nearest neighboring pairs are uniform, i.e., t(i,i+1)=t(i+1,i+2) (i=1,2,3,...). The other one is quarter-filled and the hopping matrixes alternate every four lattice constants with t(i,i+1)=t(i+1,i+2)not equalt(i+2,i+3)=t(i+3,i+4) (i=1,5,9,...). Results of the two examples are reasonable. |
