光掺杂莫特绝缘体的超导光学响应

Superconducting optical response of photodoped Mott insulators

Jiajun Li, Denis Golez, Philipp Werner, Martin Eckstein

摘要:

超快激光脉冲可以在极短的时间尺度上重新分布莫特绝缘体中的电荷,导致光生载流子的快速产生。最近的研究表明,这些光生载流子可以在低温下形成一种新的$η$ --成对的凝聚体,其特征在于交错的超导配对场。在这篇会议论文中,我们讨论了起源的$η$ -配对隐藏的相位和它的光学响应,可以检测到的泵浦探测实验。隐藏相可能与莫特绝缘体中可能的光致超导性有关。

英文摘要:

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.
