论文摘要
我们研究了一对倾斜双孔电势中一对一维玻色粒准谐照之间的隧道耦合的浮雕工程。通过调节两个孔之间的能量差，我们重新建立隧道耦合并精确控制其振幅和相位。这使我们能够在两种最初不相关的玻色气体之间引发连贯性，并在新兴的正弦 - 戈登哈密顿量中准备不同的初始状态。我们充分表征了浮点系统，并研究了平衡特性和放松对调制的依赖性。
We study Floquet engineering of the tunnel coupling between a pair of one-dimensional bosonic quasi-condensates in a tilted double-well potential. By modulating the energy difference between the two wells, we re-establish tunnel coupling and precisely control its amplitude and phase. This allows us to initiate coherence between two initially uncorrelated Bose gases and prepare different initial states in the emerging sine-Gordon Hamiltonian. We fully characterize the Floquet system and study the dependence of both equilibrium properties and relaxation on the modulation.
