Strong light–matter coupling in quantum cavities provides a pathway to break fundamental materials symmetries, like time-reversal symmetry in chiral cavities. This Comment discusses the potential to realize non-equilibrium states of matter that have so far been only accessible in ultrafast and ultrastrong laser-driven materials.

具有手性光学腔的工程量子材料

量子腔中的强光-质耦合提供了打破基本材料对称性的途径，例如手性腔中的时间反转对称性。该评论讨论了实现物质非平衡状态的潜力，而这种状态迄今为止仅在超快和超强激光驱动的材料中才能实现。
