此研究的終極目標在於探究孤立的量子系統如何達到熱平衡。為此,我們打
造一個帶自旋的原子玻色-愛因思坦凝結實驗,除了可觀察量子氣體達熱平衡動
態過程之外,亦可測試一些關於熱平衡的必要條件及假說, 包含本徵態熱平衡假
說、以及系統的可積性等。
此外,我們提供一個可以利用此系統研究物理的實例。我們針對自旋-質心旋
轉角動量耦合的物理現象,進行實驗上的驗證。透過雷射光各種可調控的參數,
可以讓原子團產生在空間上的角動量分布,用以形成自旋-角動量的糾纏態。

In this thesis, we aimed to study the dynamics of thermalization in a
closed quantum system. We constructed an atomic spinor Bose-Einstein
condensates (BEC) experiment to study the related issues. The spinor BEC
provides a suitable platform to test the theories about thermalization in an
isolated environment. Our spinor system will enable the tests of the related
theories, such as the eigenstate thermalization hypothesis (ETH) and the
integrability of the quantum system.
Meanwhile, we provide an example of quantum simulation. We demonstrated the spin-orbital angular momentum coupling in spinor BEC. The
phenomenon reveals the spatial dependent distribution of angular momentum. It is capable to control such coupling by engineering our laser light.
