摘要：
我们引入了载波漂移调制——一种创建时间边界和使光时间晶体成为可能的新机制。这种方法为双曲时间超材料开辟了直接的路线，特别是双曲时间晶体。我们证明，负责时间晶体形成的过程可以同时补偿支撑介质中的固有材料损耗——克服了纳米光子学中的一个核心挑战。真正无损耗的双曲介质的实现，长期以来被认为是纳米光子学的关键挑战之一，为亚波长光聚焦、强场物理和新型光-物质相互作用领域打开了新的可能性。关键的是，所提出的方法可以使用现有材料和 readily available 光源实现，使其既实用又具有变革性。
英文摘要：
We introduce the Carrier Drift Modulation - a new mechanism for creating temporal boundaries and enabling photonic time crystals. This approach opens a direct route to hyperbolic temporal metamaterials and, in particular, hyperbolic time crystals. We demonstrate that the very process responsible for time crystal formation can simultaneously compensate for intrinsic material losses in the supporting medium - overcoming one of the central challenges in nanophotonics. The realization of truly lossless hyperbolic media, long considered as one of the key challenges of nanophotonics, unlocks new possibilities for subwavelength light focusing, strong-field physics, and novel regimes of light-matter interaction. Crucially, the proposed approach can be implemented using existing materials and readily available light sources, making it both practical and transformative.
