论文摘要
我们在实验上使用三个地面Zeeman状态实现了自旋量量耦合（STMC）。这种新型的STMC由两个明亮态带作为常规的自旋轨道耦合自旋-1/2系统和一个深色状态中间带。使用射频自旋注射光谱法，我们研究了STMC的能带。证明中间状态是STMC系统中的黑暗状态。实现的STMC能量带可能打开门，以进一步探索外来量子问题。
We experimentally realize the spin-tensor momentum coupling (STMC) using the three ground Zeeman states coupled by three Raman laser beams in ultracold atomic system of $^{40}$K Fermi atoms. This new type of STMC consists of two bright-state bands as a regular spin-orbit coupled spin-1/2 system and one dark-state middle band. Using radio-frequency spin-injection spectroscopy, we investigate the energy band of STMC. It is demonstrated that the middle state is a dark state in the STMC system. The realized energy band of STMC may open the door for further exploring exotic quantum matters.
