摘要：
我们考虑了在标量玻色-爱因斯坦凝聚体背景下传播的费米子的色散关系。利用费米子与标量场之间简单的汤川型耦合模型，讨论了一些说明性示例。在这些情形下，色散关系被明确确定到最低阶。该方法还允许确定由与玻色-爱因斯坦凝聚体激发相互作用引起的色散关系的修正。指出了结果可能应用于中微子情形。
英文摘要：
We consider the dispersion relations of fermions that propagate in the background of a scalar Bose-Einstein condensate. Some illustrative examples are discussed using simple Yukawa-type coupling models between the fermions and the scalar fields. The dispersion relations are determined explicitly in those cases, to the lowest order. The method also allows to determine the corrections to the dispersion relations due to the interactions with the excitations of the Bose-Einstein condensate. Possible applications of the results to the case of neutrinos are indicated.
