STIRAP(受激拉曼绝热通道)是一种强大的基于激光的方法，通常涉及两个光子，用于在量子态之间高效和选择性地转移布居。一个特别有趣的特征是，初始和最终量子态之间的耦合是通过中间态进行的，尽管后者的寿命可能比与激光辐射的相互作用时间短得多。然而，从中间态发出的自发辐射被量子干涉所阻止。在整个转移过程中保持初始状态和最终状态之间的一致性至关重要。STIRAP最初是为了在化学动力学中的应用而开发的。这就是为什么1990年的原始论文发表在《化学物理杂志》上的原因。然而，从大约2000年开始，STIRAP的独特能力和对某些实验参数微小变化的稳健性刺激了许多研究人员将该方案应用于各种其他物理领域。这些努力的成功记录在这一系列文章中。在A部分中，记录了STIRAP在固态环境中操纵或控制分子、光子、离子甚至量子系统的实验成功。在简要介绍了STIRAP的基本物理之后，讨论了该方法在形成超冷分子中的核心作用，然后介绍了精密实验(测量电子的电偶极矩上限或检测手性分子中宇称破坏的后果)或超低温化学动力学研究如何受益于STIRAP。接下来是基于STIRAP的对腔内光子的控制，然后是一组三个贡献，通过提供关于波(光子、磁子和声子)在各自的波导之间的传输的数据，突出了STIRAP概念在经典物理中的潜力。关于离子或离子串的工作讨论了应用的选择，例如在量子信息中。最后，介绍了STIRAP在控制操纵固态系统中的量子态方面的成功，这些系统通常不利于相干过程，处理稀土离子掺杂晶体和氮空位(NV)中心甚至超导量子电路中的数据存储。关于离子和涉及固态系统的工作强调了结果与量子信息协议的相关性。B部分涉及理论工作，包括与量子信息或调用STIRAP来操纵物质波有关的更多概念。随后的文章讨论了正在进行的实验，以展示STIRAP的潜力，否则无法进入分子的里德堡态，或者控制和冷却分子束中粒子的平移运动，或者角动量态的极化。这一系列文章的结论是，STIRAP在核物理中的应用更具投机性，如果获得合适的辐射场，可能会产生壮观的结果。
STIRAP (stimulated Raman adiabatic passage) is a powerful laser-based method, usually involving two photons, for efficient and selective transfer of populations between quantum states. A particularly interesting feature is the fact that the coupling between the initial and the final quantum states is via an intermediate state, even though the lifetime of the latter can be much shorter than the interaction time with the laser radiation. Nevertheless, spontaneous emission from the intermediate state is prevented by quantum interference. Maintaining the coherence between the initial and final state throughout the transfer process is crucial. STIRAP was initially developed with applications in chemical dynamics in mind. That is why the original paper of 1990 was published in The Journal of Chemical Physics. However, from about the year 2000, the unique capabilities of STIRAP and its robustness with respect to small variations in some experimental parameters stimulated many researchers to apply the scheme to a variety of other fields of physics. The successes of these efforts are documented in this collection of articles. In Part A the experimental success of STIRAP in manipulating or controlling molecules, photons, ions or even quantum systems in a solid-state environment is documented. After a brief introduction to the basic physics of STIRAP, the central role of the method in the formation of ultracold molecules is discussed, followed by a presentation of how precision experiments (measurement of the upper limit of the electric dipole moment of the electron or detecting the consequences of parity violation in chiral molecules) or chemical dynamics studies at ultralow temperatures benefit from STIRAP. Next comes the STIRAP-based control of photons in cavities followed by a group of three contributions which highlight the potential of the STIRAP concept in classical physics by presenting data on the transfer of waves (photonic, magnonic and phononic) between respective waveguides. The works on ions or ion strings discuss options for applications, e.g. in quantum information. Finally, the success of STIRAP in the controlled manipulation of quantum states in solid-state systems, which are usually hostile towards coherent processes, is presented, dealing with data storage in rare-earth ion doped crystals and in nitrogen vacancy (NV) centers or even in superconducting quantum circuits. The works on ions and those involving solid-state systems emphasize the relevance of the results for quantum information protocols. Part B deals with theoretical work, including further concepts relevant to quantum information or invoking STIRAP for the manipulation of matter waves. The subsequent articles discuss the experiments underway to demonstrate the potential of STIRAP for populating otherwise inaccessible high-lying Rydberg states of molecules, or controlling and cooling the translational motion of particles in a molecular beam or the polarization of angular-momentum states. The series of articles concludes with a more speculative application of STIRAP in nuclear physics, which, if suitable radiation fields become available, could lead to spectacular results.
