摘要翻译:
我们用T-矩阵近似计算了低温下费米子原子气体正态的单粒子谱。在极化气体的强相互作用区,我们发现频谱分成两个分支,导致了双峰的射频频谱特征。

英文摘要:
We use a T-matrix approximation to calculate the single particle spectrum of the normal state of a gas of Fermionic atoms at low temperature. In the strongly interacting regime of the polarized gas, we find that the spectrum is separated in two branches, leading to a double-peaked radiofrequency spectral feature.
