Description
Bose Einstein Condensates (BECs) confined in a trap allow us to study the excitation between eigenfunctions of a given trap potential, which can be directly calculated from quantum mechanics. Here we study the spinor collective excitations, in other words, the collective excitations of different spin components. Specifically, the spinor collective modes in a 3D harmonic trap will be presented. Moreover, different types of collective excitations in this trap, collective mode mixing as well as their applications will be discussed.
