【报告摘要】: At ultra-low temperatures atoms behave like waves described by their de Broglie wavelengths. The ability to control coherence and explore wave–particle duality makes de Broglie matter waves central to emerging quantum technologies. In this seminar, I present a toolbox for controlling and manipulating the dynamics of ultracold atoms and discuss the application of the ultracold atoms in quantum simulations leading to a range of cutting-edge applications, such as, quantum computers, quantum microscopy, gravitometry. The presence of external periodic modulation in these atomic systems provides additional parametric control. I explain the canonical quantization of the modulated atomic system using gauge transformation.
在超低温下，原子呈现由其德布罗意波长刻画的波动行为。对相干性的可控操控与对波粒二象性的探索，使德布罗意物质波成为新兴量子技术的核心要素。本文报告将介绍一套用于控制与操纵超冷原子动力学的“方法学工具箱”，并讨论其在量子模拟中的应用，进而通向一系列前沿方向，如量子计算、量子显微术与重力测量等。外加的周期性调制为这些原子体系提供了额外的参数调控自由度。最后，我将通过规范变换阐述该受调制原子体系的正则量子化处理。
