| 中文摘要 | In the present paper, we compute the superfluid density of two-dimensional weakly interacting boson system at zero temperature using one-loop renormalization group calculations under the scheme of newly derived formula [M. Holzmann and G. Baym Phy. Rev. B 76, 092502 (2007)]. We find that the interactions between the boson particles are marginally irrelevant in the renormalization group sense. The fluctuations of high-energy scale enhance superfluid density compared with the result of the mean-field approximation. The correction has (ln mu) form, where mu is the chemical potential of the boson system. |
