摘要:

物质波的研究是量子物理学的一个蓬勃发展的领域,最近激发了许多关于电子、中子、原子、玻色凝聚系综、冷团簇和热分子的研究。复杂物体的相干性实验对于探索向经典物理学的过渡、测量分子性质以及测试新的时空模型都很有意义。对于复杂分子的物质波实验,衍射分子和光栅壁之间相互作用的强色散效应是一个主要挑战,因为它对分子束的速度选择施加了巨大的限制。我们在这里描述的第一个实验实现的一个新的干涉仪,解决了这个问题相结合的优点Talbot-Lau设置的光学相位光栅的好处,我们显示量子干涉与新的大分子。

英文摘要:

Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clusters and hot molecules. Coherence experiments with complex objects are of interest for exploring the transition to classical physics, for measuring molecular properties and they have even been proposed for testing new models of space-time. For matter-wave experiments with complex molecules, the strongly dispersive effect of the interaction between the diffracted molecule and the grating wall is a major challenge because it imposes enormous constraints on the velocity selection of the molecular beam. We here describe the first experimental realization of a new interferometer that solves this problem by combining the advantages of a Talbot-Lau setup with the benefits of an optical phase grating and we show quantum interference with new large molecules.
