title = "Spin-charge separation in ultracold quantum gases",
abstract = "A double component Fermi gas confined in a one dimensional (1D) harmonics trap was analytically studied. Based on the Luttinger model (LM), the nature of the excitations was investigated. Through experiments, spin-charge separation was observed directly.",
