Big time crystals: a new paradigm in condensed matter

该项目旨在利用周期性驱动的玻色-爱因斯坦凝聚体产生的大时间晶体，将凝聚态物理扩展到时间维度。这样的系统有望提供特殊的多功能性，允许通过适当的周期性驱动和粒子相互作用的调制来几乎随意地设计时间晶格中的有效势和远程相互作用。预期的结果包括实现新的凝聚态现象，例如在时间维度上的拓扑保护态，表现出无序或准晶体有序的时间晶体结构，以及类似于电子学的时间电子学装置。未来的潜在好处包括新型先进材料和类似半导体的器件。

This project aims to extend condensed matter physics to the time dimension using big time crystals created by a periodically driven Bose-Einstein condensate. Such a system is expected to offer exceptional versatility, allowing effective potentials and long-range interactions in a time lattice to be engineered almost at will by proper periodic driving and modulation of the particle interaction. Expected outcomes include realisation of novel condensed matter phenomena such as topologically protected states in the time dimension, time crystalline structures exhibiting disorder or quasi-crystalline order and time-tronics devices analogous to electronics. Potential future benefits include novel advanced materials and semiconductor-like devices.
