AI 中文摘要
光学手性密度被广泛用作描述电磁场及其与各向同性手性介质相互作用的手性特性的标量度量。然而，在各向异性旋光介质中，单一标量通常不足以捕捉手性场 - 物质耦合的全部复杂性。在这项工作中，我们超越了传统的光学手性密度，基于利普金形式主义引入了电磁手性张量。该张量对手性电磁场提供了更丰富且物理上更透明的描述，特别是在其与一般磁电介质相互作用的背景下。我们讨论了各个张量分量的物理意义，并给出了在各向异性手性场存在下小各向异性手性分子激发率的表达式。
英文摘要
Optical chirality density is widely used as a scalar measure for describing the chiral properties of electromagnetic fields and their interaction with isotropic chiral media. However, in anisotropic optically-active media, a single scalar quantity is generally insufficient to capture the full complexity of chiral field-matter coupling. In this work, we go beyond the conventional optical chirality density and introduce a tensor of electromagnetic chirality based on the Lipkin formalism. This tensor provides a richer and more physically transparent description of chiral electromagnetic fields, particularly in the context of their interaction with general magneto-electric media. We discuss the physical meaning of the individual tensor components and provide an expression for the excitation rate of small anisotropically chiral molecules in the presence anisotropically chiral fields.
