The tremendous progress in experimental and theoretical atomic, molecular and optical science over the past decades opens today new avenues for tailoring and controlling matter on the quantum level. In this research field, cold and ultracold atomic and molecular systems play a key role in understanding quantum properties and quantum dynamics in well-defined systems. Related research also develops applied aspects for quantum information, metrology and laser applications, and provides far reaching progress in modern technology. The proposed International Research Training Group (IRTG) focuses on Cold Controlled Atomic and Molecular Ensembles to study a wide range of phenomena in physics and chemistry. The research program will break new ground in producing and characterizing cooled and trapped atomic and molecular systems and using state selectivity and quantum control to study properties and dynamics of the systems. Experimentally, the program combines groups in the fields of ultracold atoms, ion traps, cold molecules and clusters, and quantum control with femtosecond lasers. The complementary expertise of the theorists (DFT calculations, quantum chemistry, molecular dynamics, reactive scattering, quantum manybody simulations, molecules in strong fields, macroscopic QED) adds solid theoretical background for the research program. The IRTG will provide a structured doctoral program including seminars, summer schools, meetings and guest programs on the highest international scientific level. The research is of interdisciplinary character and will connect to diverse fields of atomic and molecular physics, quantum optics, condensed-matter physics, and physical chemistry. The involved groups will efficiently foster synergy effects in technological developments, scientific achievements as well as for creating a unique training environment for young scientists. All doctoral projects will be embedded into binational collaborations and include long-term stays at both locations. Doctoral projects will be co-supervised, having one German and one Canadian supervisor. A continuous assessment and support of the project work at different levels as well as measures promoting gender equality will be an integral part of the program. The extended working periods in Freiburg and Vancouver offer a tremendous advantage for the qualification of the doctoral students both for a future career in academia as well as in industry due to the added interdisciplinary and intercultural experiences.

在过去的几十年里，原子、分子和光学科学在实验和理论上的巨大进步为在量子水平上裁剪和控制物质开辟了新的途径。在这个研究领域中，冷和超冷原子和分子系统在理解定义良好的系统中的量子特性和量子动力学方面起着关键作用。相关研究还为量子信息、计量学和激光应用开辟了应用领域，为现代技术提供了深远的进步。拟议的国际研究训练组（IRTG）侧重于冷控制原子和分子集成，以研究物理和化学中的广泛现象。该研究计划将在生产和表征冷却和捕获的原子和分子系统以及使用状态选择和量子控制来研究系统的性质和动力学方面开辟新天地。在实验上，该项目结合了超冷原子、离子阱、冷分子和簇以及飞秒激光量子控制领域的研究小组。理论专家（DFT计算，量子化学，分子动力学，反应散射，量子多体模拟，强场分子，宏观QED）的互补专业知识为研究计划增加了坚实的理论背景。IRTG将提供结构化的博士课程，包括研讨会、暑期学校、会议和最高国际科学水平的客座课程。本研究具有跨学科的特点，将涉及原子与分子物理、量子光学、凝聚态物理和物理化学等多个领域。参与小组将有效地促进技术发展、科学成就的协同效应，并为青年科学家创造独特的培训环境。所有博士项目都将纳入两国合作，并包括在两国的长期停留。博士项目将由一名德国和一名加拿大导师共同指导。持续评估和支持不同层次的项目工作以及促进性别平等的措施将是该方案的一个组成部分。由于增加了跨学科和跨文化的经验，弗赖堡和温哥华延长的工作时间为博士生在学术界和工业界的未来职业生涯提供了巨大的优势。
