Novel non-equilibrium states of matter in periodically driven spin systems

在凝聚态、固态和原子物理的界面上的理论/实验创举。其目的是对周期性驱动的自旋系统中物质的新的非平衡态有一个基本的理解。一个最好的例子是时间晶体，它是当耦合到周期驱动器时具有亚谐响应的多体系统。发展这类系统的基础理论，并在各种实验平台上实现和验证，为制备和控制在固态和量子增强技术中应用的量子非平衡材料开辟了新的可能性。

A theoretical/ experimental initiative at the interface of condensed matter, solid state and atomic physics. The aim is to develop a fundamental understanding of novel non-equilibrium states of matter in periodically driven spin systems. A prime example are time crystals, which are many-body systems with a subharmonic response when coupled to a periodic drive. Developing a fundamental theory for such systems, and its implementation and verification in various experimental platforms, opens up new possibilities for the preparation and control of quantum non-equilibrium materials with applications in both solid-state and quantum-enhanced technologies.
