Boson-Fermion pairing in Bose-Fermi mixtures on 1D optical lattices

X. Barillier-Pertuisel, S. Pittel, L. Pollet, P. Schuck

摘要:

玻色子费米子配对被认为是在一个离散的玻色子和完全自旋极化的费米子的环境中,通过一个有吸引力的玻色费米哈伯德哈密顿耦合在一维。的T-矩阵近似的粒子的质量相同,并在双半填充的结果进行了比较,与精确对角化的结果和量子蒙特卡罗结果。结果表明,大部分量子点的计算结果与理论值吻合较好,同时也证实了稳定的弱耦合配对模式的出现。

英文摘要:

Boson-fermion pairing is considered in a discrete environment of bosons and fully spin-polarized fermions, coupled via an attractive Bose-Fermi Hubbard Hamiltonian in one dimension. The results of the T-matrix approximation for particles of equal mass and at double half filling are compared with the results of exact diagonalization and with Quantum Monte Carlo results. Satisfactory agreement for most quantities is found. The appearance of a stable, weak-coupling pairing mode is also confirmed.
