| 中文摘要 | The finite size scaling behavior of superfluid-insulator transition in the one-dimensional Bose-Hubbard model is studied. It is shown that the superfluid density of the system with finite size has a maximum at a certain interaction U-m and the derivative of superfluid density has a minimum at a certain interaction U-d. The critical point U-c can be quantified by the scaling analysis of either U-m or U-d. The transition point U-m tends to the critical point U-c from the region of U < U-c, while the U-d tends to the U-c from the region of U > U-c. The transition points U-m and U-d satisfy different finite size scaling laws and have the different critical exponents. The divergence speed of the superfluid density is much smaller than that of its derivative at the critical point. |
