论文摘要

我们通过在弱相互作用的方面使用行列式量子蒙特卡洛方法在有限的温度下在有限温度下在有限温度下的方格上研究二维玻色纤维纤维。在这里,我们考虑了有吸引力的Bose-Hubbard模型和免费的无旋转费米子。在没有钾盐相互作用的情况下,我们获得了有吸引力玻色子的倒塌状态的边界。在存在玻色子 - 弗米族相互作用的情况下,就玻色子处于超流体状态而言,费米子之间的有效P波相互作用将被诱导。此外,我们发现在低温下复合费米对的出现。

We study the two-dimensional Bose-Fermi mixture on square lattice at finite temperature by using the determinant quantum Monte Carlo method within the weakly interacting regime. Here we consider the attractive Bose-Hubbard model and free spinless fermions. In the absence of bosonfermion interactions, we obtain the boundary of the collapsed state of the attractive bosons. In the presence of boson-fermion interactions, an effective p-wave interaction between fermions will be induced as far as the bosons are in a superfluid state. Moreover, we find the emergence of the composite fermion pairs at low temperatures.
