我们提出在作为梯度量子物质的超冷气体中进行可编程自旋转换，其自旋相关的自能在空间中变化。量子动力学理论表明，耗散自能曲率将力驱动的标量各向异性转变为具有混合纵向 - 横向动量宇称的自旋源。自旋分辨飞行时间成像可揭示当驱动或编程曲率反转时符号改变的横向自旋纹理。超冷气体因此为梯度量子物质提供了可控自旋源。
英文摘要
We propose programmable spin conversion in ultracold gases as gradient quantum matter, whose spin-dependent self-energy varies in space. Quantum kinetic theory shows that a dissipative self-energy curvature turns a force-driven scalar anisotropy into a spin source with mixed longitudinal-transverse momentum parity. Spin-resolved time-of-flight imaging can reveal a transverse spin texture that changes sign when either the drive or programmed curvature is reversed. Ultracold gases thereby offer a controllable spin source for gradient quantum matter.
