在具有竞争或耦合电子序的系统中，激光驱动可以导致序的增强，甚至导致没有平衡模拟的隐藏相的出现。在这里，我们考虑一个模型A3 C60表现出一个独特的传统和奇频（或复合）订单之间的相互作用。特别是，我们表明，光掺杂的反铁磁莫特绝缘相，实现在Cs3 C60，结果在一个顺磁带隙状态与轨道对称性破缺。这种隐藏相在平衡条件下不存在，可以解释为奇频轨道有序态，并且在概念上与更弱相关化合物中的平衡Jahn-Teller金属有关。我们的研究表明，通过磁序的非热熔化的纯奇频序的外观，并提供了一个有趣的例子，在多轨道系统中的电子顺序的非平衡控制。
Laser driving in systems with competing or coupled electronic orders can lead to the enhancement of orders, or even to the appearance of hidden phases without an equilibrium analogue. Here we consider a model for A3C60 which exhibits a unique interplay between conventional and oddfrequency (or composite) orders. In particular, we show that photo-doping of the antiferromagnetic Mott insulating phase, as realized in Cs3C60, results in a paramagnetic gapped state with broken orbital symmetry. This hidden phase, which does not exist under equilibrium conditions, can be interpreted as an odd-frequency orbital-ordered state, and is conceptually related to the equilibrium Jahn-Teller metal in more weakly correlated compounds. Our study demonstrates the appearance of pure odd-frequency order via the nonthermal melting of magnetic order, and provides an interesting example of nonequilibrium control of electronic orders in a multi-orbital system.
