论文摘要
研究具有二维(2D)系统的平衡外动力学具有广泛的理论利益,因为这些系统受到波动的强烈影响,并且在有限温度下存在超氟相变。在这项工作中,我们意识到了对退化的bose气体的物质干扰,包括使用磁陷阱电势首次证明2D Bose气体相干分裂。我们通过仅成像一小部分扩展的原子云来改善条纹对比度,这对于随后在量子淬灭后对气体放松的研究是必不可少的。
Investigating out-of-equilibrium dynamics with two-dimensional (2D) systems is of widespread theoretical interest, as these systems are strongly influenced by fluctuations and there exists a superfluid phase transition at a finite temperature. In this work, we realise matter-wave interference for degenerate Bose gases, including the first demonstration of coherent splitting of 2D Bose gases using magnetic trapping potentials. We improve the fringe contrast by imaging only a thin slice of the expanded atom clouds, which will be necessary for subsequent studies on the relaxation of the gas following a quantum quench.
