论文摘要
超快速激光脉冲可以在极短的时间尺度上重新分布莫特绝缘子的电荷，从而导致快速产生的光载体。最近已经证明，这些光载体可以形成一种新颖的$η$ - 在低温下配对的凝结物，具有交错的超导配对场。在本会议论文中，我们讨论了$η$的来源 - 配对的隐藏阶段及其光学响应，可以在泵探针实验中检测到。隐藏相可能与Mott绝缘子中可能的光诱导的超导性有关。
Ultrafast laser pulses can redistribute charges in Mott insulators on extremely short time scales, leading to the fast generation of photocarriers. It has recently been demonstrated that these photocarriers can form a novel $η$--paired condensate at low temperatures, featuring a staggered superconducting pairing field. In this conference paper, we discuss the origin of the $η$--paired hidden phase and its optical response which may be detected in a pump-probe experiment. The hidden phase may be relevant for possible light-induced superconductivity in Mott insulators.
