论文摘要
我们描述了一个合成的三腿梯子梯子系统，其中性$^{173} $ yb原子在一维光学晶格中。梯子腿是由原子的三个高精细地面自旋状态形成的，并且使用多个激光束在旋转状态之间通过拉曼耦合产生复杂的文字链接。通过梯子plaquette $ ϕ $的有效磁通量由带有晶格轴的拉曼激光束的角度控制。我们研究了$ ϕ \ of th hall梯子系统的淬火动力学，大约\fracπ{3}，\fracπ{2}，$和$ \ frac {2π} {3} {3} $在突然应用于拉曼耦合在各种interleg链接中。自旋组成和晶格位置平面中原子的半古典轨迹表现出有效磁场的特征运动。在带有三腿循环链接的管构型中，观察到淬灭的演化基本上减弱，这归因于霍尔管的随机通量螺纹。
We describe a synthetic three-leg Hall ladder system with a tunable magnetic flux for neutral $^{173}$Yb atoms in a one-dimensional optical lattice. The ladder legs are formed by three hyperfine ground spin states of the atoms, and the complex interleg links are generated through Raman couplings between the spin states using multiple laser beams. The effective magnetic flux through a ladder plaquette, $ϕ$, is controlled by the angles of the Raman laser beams with the lattice axis. We investigate the quench dynamics of the Hall ladder system for $ϕ\approx\fracπ{3}, \fracπ{2},$ and $\frac{2π}{3}$ after a sudden application of the Raman coupling in various interleg link configurations. The semi-classical trajectory of the atoms in the plane of the spin composition and lattice position exhibits the characteristic motion for the effective magnetic field. In a tube configuration with the three legs cyclically linked, the quench evolution was observed to be substantially damped, which is attributed to the random flux threading the Hall tube.
