We present 3D numerical simulation results of moving vortex lattices in the presence of 1D correlated disorder at zero temperature. Our results with field tilting confirm the theoretical predictions of a moving Bose glass phase, characterized by transverse pinning and dynamical transverse Meissner effect, the moving flux lines being localized along the correlated disorder direction. Beyond a critical transverse field, vortex lines exhibit along all their length a "kink" structure resulting from an effective static "tin roof" pinning potential in the transverse direction.
我们展示了在零温度下存在一维相关无序时移动涡旋晶格的三维数值模拟结果。我们通过场倾斜得到的结果证实了移动玻色玻璃相的理论预测，其特征为横向钉扎和动态横向迈斯纳效应，移动的磁通线沿相关无序方向局域化。超过临界横向场时，涡旋线在其整个长度上呈现出一种“扭结”结构，这是由横向方向上有效的静态“锡屋顶”钉扎势导致的。
