论文摘要
今天，我们目睹了手性测量中的电偶极革命。 Here we reflect on its lessons and outcomes, such as the perspective on chiral measurements using the complementary principles of "chiral reagent" and "chiral observer", the hierarchy of scalar, vectorial and tensorial observables, the new properties of the chiro-optical response in the ultrafast and non-linear domains, and the geometrical magnetism associated with the chiral response in photoionization.电动旋转革命是一个具有里程碑意义的事件。它已经通过新方法家庭开辟了极有效的对映对照歧视的路线。这些方法受相同的原则支配，但在截然不同的方向上起作用 - 从微波到光学光；它们解决了所有分子自由度 - 电子，振动和旋转，并使用柔性检测方案，即检测光子或电子，使其适用于不同的手性相，从气体到液体，再到液体固体。电 - 偶极革命还使对对映射的手性分子具有光。这种操作包括在手性分子的振动状态下令人兴奋的和控制超快的螺旋电流，对电子，振动和旋转分子状态中种群的对映体敏感的控制，并为chiral分子的有效映射分离和对映体敏感捕获开辟了道路。 “透视”一词具有两个含义：“ Outlook”和“观点”。在这篇文章中，我们试图涵盖这两种含义。
Today we are witnessing the electric-dipole revolution in chiral measurements. Here we reflect on its lessons and outcomes, such as the perspective on chiral measurements using the complementary principles of "chiral reagent" and "chiral observer", the hierarchy of scalar, vectorial and tensorial observables, the new properties of the chiro-optical response in the ultrafast and non-linear domains, and the geometrical magnetism associated with the chiral response in photoionization. The electric-dipole revolution is a landmark event. It has opened routes to extremely efficient enantio-discrimination with a family of new methods. These methods are governed by the same principles but work in vastly different regimes -- from microwaves to optical light; they address all molecular degrees of freedom -- electronic, vibrational and rotational, and use flexible detection schemes, i.e. detecting photons or electrons, making them applicable to different chiral phases, from gases to liquids to amorphous solids. The electric-dipole revolution has also enabled enantio-sensitive manipulation of chiral molecules with light. This manipulation includes exciting and controlling ultrafast helical currents in vibronic states of chiral molecules, enantio-sensitive control of populations in electronic, vibronic and rotational molecular states, and opens the way to efficient enantio-separation and enantio-sensitive trapping of chiral molecules. The word "perspective" has two meanings: "outlook" and "point of view". In this perspective article, we have tried to cover both meanings.
