Active glassy matter has recently emerged as a novel class of non-equilibrium soft matter, combining energy-driven, active particle movement with dense and disordered glass-like behavior. Here we review the state-of-the-art in this field from an experimental, numerical, and theoretical perspective. We consider both non-living and living active glassy systems, and discuss how several hallmarks of glassy dynamics (dynamical slowdown, fragility, dynamical heterogeneity, violation of the Stokes-Einstein relation, and aging) are manifested in such materials. We start by reviewing the recent experimental evidence in this area of research, followed by an overview of the main numerical simulation studies and physical theories of active glassy matter. We conclude by outlining several open questions and possible directions for future work.
活性玻璃态物质最近已成为一类新型的非平衡软物质，它将能量驱动的活性粒子运动与致密且无序的类玻璃行为结合在一起。在此，我们从实验、数值模拟和理论的角度综述该领域的最新进展。我们考虑了非生命和生命活性玻璃态系统，并讨论了玻璃态动力学的几个特征（动力学减速、脆性、动力学不均匀性、斯托克斯-爱因斯坦关系的违背以及老化）在这类材料中是如何体现的。我们首先回顾该研究领域的最新实验证据，接着概述活性玻璃态物质的主要数值模拟研究和物理理论。最后，我们概述了几个开放性问题以及未来工作的可能方向。
