We report on a chiral optical Stern-Gerlach experiment where chiral liquid crystal microspheres are selectively displaced by means of optical forces arising from optical helicity gradients. The present Newtonian experimental demonstration of an effect predicted at molecular scale [New J. Phys. 16, 013020 (2014)NJOPFM1367-263010.1088/1367-2630/16/1/013020] is a first instrumental step in an area restricted so far to theoretical discussions. Extending the Stern-Gerlach experiment legacy to chiral light-matter interactions should foster further studies, for instance towards the elaboration of chirality-enabled quantum technologies or spin-based optoelectronics.
我们报告了一个手性光学斯特恩-格拉赫实验，其中手性液晶微球通过光学螺旋度梯度产生的光学力被选择性地置换。本实验是对分子尺度上预测的一种效应的牛顿式验证[New J. Phys. 16, 013020 (2014)NJOPFM1367-263010.1088/1367-2630/16/1/013020]，这在手性光物质相互作用的领域中是一个受限的理论讨论的第一个仪器步骤。将斯特恩-格拉赫实验的传统扩展到手性光物质相互作用，应该会促进进一步的研究，例如朝着发展基于手性的量子技术或基于自旋的光电子学的方向发展。
