项目摘要

Traditional laser spectroscopy is based on controlling and characterizing intensity, duration, and phase of the light source/emission. Besides these classical aspects, laser fields also contain intrinsic fluctuations which inevitably lead to intriguing quantum-optical features. In this project, we will investigate how the quantitative control and systematic utilization of these quantum effects can be applied to broaden and complement the scope of classical semiconductor spectroscopy. In particular, we will analyze how and to which degree this quantum-optical spectroscopy can be used for the superior experimental characterization of the optically generated matter states. Furthermore, we will investigate new schemes to generate particular many-body configurations with desired correlation properties, such as spatial long-range order or reduced Coulombic dephasing. Technically, we combine quantum-optical methodologies with our correlation-expansion method to simultaneously treat the many-body and quantum-optical effects in semiconductors. Besides the systematic calculation of the many-body states and their interactions, we will also characterize the quantum statistics of the re-emitted light. We will collaborate with groups in Germany and USA performing quantitative experiments designed to test relevant aspects of the theoretical predictions.

传统的激光光谱学基于控制和表征光源/发射的强度、持续时间和相位。除了这些经典的方面，激光场也包含内在的波动，这不可避免地导致有趣的量子光学功能。在这个项目中，我们将研究如何定量控制和系统地利用这些量子效应可以应用于扩大和补充经典半导体光谱学的范围。特别是，我们将分析如何以及在何种程度上可以使用这种量子光学光谱学的光学产生的物质状态的上级实验表征。此外，我们将研究新的计划，以产生特定的多体配置与所需的相关性能，如空间长程有序或减少库仑退相。在技术上，我们将联合收割机量子光学方法与关联展开方法结合起来，同时处理半导体中的多体效应和量子光学效应。除了系统地计算多体态及其相互作用外，我们还将描述再发射光的量子统计特性。我们将与德国和美国的团队合作，进行定量实验，以测试理论预测的相关方面。
