In this contribution, we report on the implementation of a novel noise-enabled optical ratchet system. We demonstrate that, unlike commonly-used ratchet schemes-where complex asymmetric optical potentials are needed-efficient transport of microparticles across a one-dimensional optical lattice can be produced by introducing controllable noise in the system. This work might open interesting routes towards the development of new technologies aimed at enhancing the efficiency of transport occurring at the micro- and nanoscale, from novel particle-sorting tools to efficient molecular motors.
在本贡献中,我们报告了一种新型噪声增强光学棘轮系统的实现。我们证明,与常用的棘轮方案不同,通过在系统中引入可控噪声,可以在一维光学晶格中产生高效的微粒子输运,而不需要复杂的非对称光学势。这项工作可能为开发新技术开辟有趣的途径,旨在提高微纳尺度上的输运效率,从新型的粒子分选工具到高效的分子马达。
