A recent breakthrough in physics has been the proposal and observation of novel out of equilibrium phases of matter in many-body quantum systems, with time crystals as one prominent example. For these phases to be stable it is required that ergodicity is impeded, otherwise heat death of the system is inevitable. This theoretical project is aimed at studying a particular approach to impeding ergodicity: kinetic contraints, as first studied in classical systems.The project will involve both numerical and analytical approaches: Numerical experiments will provide insight into the phenomenology to be studied using analytical tools, themselves supplemented by numerical approaches.

最近物理学上的一个突破是提出并观察了多体量子系统中物质的新型非平衡相，时间晶体就是一个突出的例子。要使这些相稳定，就必须抑制遍历性，否则系统的热死是不可避免的。这个理论项目旨在研究一种阻碍遍历性的特殊方法：动力学约束，这是在经典系统中首次研究的。该项目将涉及数值和分析方法：数值实验将提供使用分析工具研究的现象学的洞察力，它们本身由数值方法补充。
