论文摘要
我们提出了一种机制，可以通过光学地沿着$ c $轴的频率驱动等离激元激发频率，从而增强了铜酸盐超导体中的层间运输。等离激元激发引起了希格斯场的集体振荡，该场诱导了超导反应的参数增强，正如我们以最小的分析模型所证明的那样。此外，我们对粒子 - 孔对称$ u（1）$晶格量表理论进行了模拟，并与我们的分析预测找到了良好的一致性。我们将层中耦合的重归其化作为光场参数的函数，并证明HIGGS模式介导的增强功能可能大于$ 50 \％$。
We put forth a mechanism for enhancing the interlayer transport in cuprate superconductors, by optically driving plasmonic excitations along the $c$ axis with a frequency that is blue-detuned from the Higgs frequency. The plasmonic excitations induce a collective oscillation of the Higgs field which induces a parametric enhancement of the superconducting response, as we demonstrate with a minimal analytical model. Furthermore, we perform simulations of a particle-hole symmetric $U(1)$ lattice gauge theory and find good agreement with our analytical prediction. We map out the renormalization of the interlayer coupling as a function of the parameters of the optical field and demonstrate that the Higgs mode mediated enhancement can be larger than $50\%$.
