论文摘要
我们建议以高$ T_C $超导体诱导时间结晶状态，通过光学地驱动HIGGS模式和Josephson等离子体模式的总和。这些基本激发耦合的通用立方体过程将驱动共振的驱动转换为两种模式的共振驱动，从而导致了不可压力的亚谐波运动。我们在三维分层晶格上使用半古典驱动的晶格理论的数值实现，该晶格建模了Cuprate超导体的几何形状，以证明这种运动对热波动的鲁棒性。我们证明了单层和双层系统的光诱导的时间晶相，并表明可以在现实的技术条件下检测到该阶用于脉冲驾驶。
We propose to induce a time crystalline state in a high-$T_c$ superconductor, by optically driving a sum resonance of the Higgs mode and a Josephson plasma mode. The generic cubic process that couples these fundamental excitations converts driving of the sum resonance into simultaneous resonant driving of both modes, resulting in an incommensurate subharmonic motion. We use a numerical implementation of a semi-classical driven-dissipative lattice gauge theory on a three-dimensional layered lattice, which models the geometry of cuprate superconductors, to demonstrate the robustness of this motion against thermal fluctuations. We demonstrate this light-induced time crystalline phase for mono- and bilayer systems and show that this order can be detected for pulsed driving under realistic technological conditions.
