超冷原子玻色-爱因斯坦凝聚的实验实现，使冷分子的产生和操纵技术得到了迅速发展，并催生了量子物质波超化学这一新的研究领域。与经典的阿克里乌斯定律相反，隧道效应主导的超冷反应可以通过高度可控的磁光技术来实现。在这些冷反应中发现了新的量子效应，如三原子分子解离的超选择性规则和量子尺寸（容器形状）效应。本文重点介绍了在这一迷人的物质波世界中所取得的各种新成就，包括冷分子组装中的量子有限数效应和双缝干涉，引发集体抽象反应的量子噪声，以及激光催化量子自旋混合气体中的磁相变。介绍了物质波超化学的实际应用，如量子光缔合的光信息存储，旋量甚至手征分子的激光增强产生等。
The experimental realization of atomic Bose-Einstein condensation at ultracold temperature has led to rapid advances in creating and manipulating cold molecules, and which has given birth to a new research field of quantum matter-wave superchemistry. Contrary to the classical Arrhenius law, the tunneling-dominated ultracold reactions can be realized through the highly-controlled magneto-optical technique. Novel quantum effects have been identified in these cold reactions, such as the super-selectivity rule in dissociating triatomic molecules, and the quantum size (vessel-shape) effect. In this review, we focus on a variety of new achievements in this fascinating matter-wave wonderland, including the quantum finite-number effect and double-slit interference in assembling cold molecules, the quantum noise in triggering collective abstraction reaction, and the magnetic phase transition in a laser-catalyzed quantum spin-mixing gas. The practical applications of matter-wave superchemistry are also introduced, such as the optical information storage via quantum photo-association, and the laser-enhanced creation of spinor or even chiral molecules.
