Interest in the multiple facets of optical vortices has flourished in the last three decades. This review examines the basic research and applications of the interplay between optical vortices and condensed-matter systems. This subfield of optical-vortex physics has rapidly developed in recent years thanks to a vigorous synergy between theory and experiment. After presenting self-contained and focused introductions to optical vortices and condensed-matter optics, theory and current progress in the research on the interaction of condensed-matter systems and optical vortices are examined. When one considers the interaction of optical vortices with condensed-matter systems, many aspects of the standard theory of the interaction of matter with plane-wave light need to be reformulated. In bulk, light-matter Hamiltonian matrix elements have to be recalculated and novel selection rules are obtained, reflecting the conservation of total angular momentum. Orbital angular momentum is transferred from the light beam to the photoexcited electrons, thereby generating macroscopic currents. Semiconductor nanostructures add the complexity of their own spatial inhomogeneity, which is handled adequately by the envelope-function approximation. Here again modified matrix elements for light-matter interactions dictate the allowed and forbidden optical transitions, which are distinct from those obtained in traditional optical excitation with smooth fields. Quantum rings play a central role due to their specially adapted geometry to the cylindrical nature of the optical-vortex beams. When the electron-electron interaction is taken into account, the rich physics of excitons and exciton polaritons comes into play and is modified by the finite orbital angular momentum of the structured light. Furthermore, the new features brought about by optical vortices in plasmonics and in the optical excitation of two-dimensional materials are reviewed. For all these systems theory and recent experiments are discussed. Finally, an overview of current and prospective applications of the interaction of optical vortices with condensed-matter systems in the fields of quantum technologies, communications, sensing, etc., is presented. Throughout this review an attempt has been made to present not only a survey of the relevant literature but also a perspective on the interesting and rapidly evolving field of optical-vortex–condensed-matter interactions.

光学涡旋和凝聚态物质之间的相互作用

在过去的三年中,人们对光学涡旋的多个方面的兴趣蓬勃发展。本综述探讨了光学涡旋与凝聚态系统之间相互作用的基础研究和应用。由于理论与实验之间的有力协同作用,光学涡旋物理学的这一子领域近年来发展迅速。在对光学涡旋和凝聚态光学进行了自成一体的重点介绍之后,考察了凝聚态系统和光学涡旋相互作用的理论和研究进展。当考虑光学涡旋与凝聚态物质系统的相互作用时,物质与平面波光相互作用的标准理论的许多方面都需要重新表述。散装,必须重新计算光物质哈密顿矩阵元素并获得新的选择规则,以反映总角动量的守恒。轨道角动量从光束转移到光激发电子,从而产生宏观电流。半导体纳米结构增加了其自身空间不均匀性的复杂性,这可以通过包络函数近似得到充分处理。在这里,用于光-物质相互作用的修改矩阵元素再次决定了允许和禁止的光学跃迁,这与在具有平滑场的传统光学激发中获得的那些不同。量子环因其特殊的几何形状与光学涡旋光束的圆柱形特性而发挥着核心作用。当考虑电子-电子相互作用时,激子和激子极化子的丰富物理学开始发挥作用,并受到结构光的有限轨道角动量的影响。此外,还回顾了等离子体激元和二维材料光激发中的光学涡旋带来的新特征。对于所有这些系统理论和最近的实验进行了讨论。最后,概述了光学涡旋与凝聚态系统相互作用在量子技术、通信、传感等领域的当前和未来应用。在整个审查过程中,不仅试图呈现对相关文献的调查,而且还试图对有趣且快速发展的光学涡旋 - 凝聚态相互作用领域进行展望。
