用于手征轻物质相互作用终极控制的局域和全局手征场
Locally and globally chiral fields for ultimate control of chiral light matter interaction
摘要：
光是最强大和精确的工具之一，使我们能够控制，塑造和创造物质的新阶段。在这项任务中，光波的磁分量到目前为止在定义波的螺旋度方面发挥了独特的作用，但它对物质的光学响应的影响很弱。手性分子提供了一个典型的例子，其中磁性相互作用的弱点阻碍了我们控制其手性光学响应强度的能力。它被限制在低于全部潜力的几个数量级。在这里，我们引入自由传播的本地和全球手征电场，手征量子系统的相互作用非常有效。为了证明这种领域的控制程度，我们专注于随机取向的手性分子的非线性光学响应。我们完全控制手性光学响应的强度，偏振和传播方向，使其无背景检测。这种反应可以完全抑制或增强，这取决于分子的手性，达到最终的限制手性歧视。我们的研究结果开辟了一条非常有效的控制手性物质和超快成像的手性结构和动力学的气体，液体和固体。
英文摘要：
Light is one of the most powerful and precise tools allowing us to control, shape and create new phases of matter. In this task, the magnetic component of a light wave has so far played a unique role in defining the wave's helicity, but its influence on the optical response of matter is weak. Chiral molecules offer a typical example where the weakness of magnetic interactions hampers our ability to control the strength of their chiral optical response. It is limited several orders of magnitude below the full potential. Here we introduce freely propagating locally and globally chiral electric fields, which interact with chiral quantum systems extremely efficiently. To demonstrate the degree of control enabled by such fields, we focus on the nonlinear optical response of randomly oriented chiral molecules. We show full control over intensity, polarization and propagation direction of the chiral optical response, enabling its background-free detection. This response can be fully suppressed or enhanced at will depending on the molecular handedness, achieving the ultimate limit in chiral discrimination. Our findings open a way to extremely efficient control of chiral matter and to ultrafast imaging of chiral structure and dynamics in gases, liquids and solids.
