Deskripsi
Cuprate superconductors are known for their intertwined interactions and coexistence of competing orders. Here, the authors observe a Fano resonance in the nonlinear THz response of La2-xSrxCuO4, which may arise from a coupling between superconducting and charge-density-wave amplitude fluctuations.
