研究了一维超流中沿玻色-爱因斯坦-凝聚(BEC)-巴丁-库珀-施里弗(BCS)交叉的拉长费米超流的Bogoliubov谱。根据流体力学理论，导出了轴向准粒子的声速、有效质量和Bogoliubov激发谱的解析表达式。我们的研究揭示了光晶格中BEC-BCS交叉的有趣特征，值得实验研究。

英文摘要：
We study the Bogoliubov spectrum of an elongated Fermi superfluid confined in an one-dimensional superfluid along the Bose-Einstein-condensate (BEC)-Bardeen-Cooper-Schrieffer (BCS) crossover. We derive analytic expressions for the sound velocity, effective mass and the Bogoliubov excitation spectrum of the axial quasiparticles long the crossover based on the hydrodynamic theory. Our investigation reveal interesting signatures of BEC-BCS crossover in an optical lattice which deserve experimental investigation.
