Signature of the Leggett mode in the A1g Raman response: from MgB2 to iron-based superconductors
T. Cea, L. Benfatto
The Raman response in a superconductor is a powerful probe to investigate the symmetry of the superconducting gap. Here we show that in a multiband superconductor it also offers th…

Nature and Raman signatures of the Higgs amplitude mode in the coexisting superconducting and charge-density-wave state
T. Cea, L. Benfatto
We investigate the behavior of the Higgs (amplitude) mode when superconductivity emerges on a preexisting charge-density-wave state. We show that the weak overdamped square-root si…
