Unravelling the glue and the competing order in superconducting cuprates

S. Caprara, C. Di Castro, B. Muschler +6

We present Raman scattering experiments in $\mathrm{L}{\mathrm{a}}_{2-\mathrm{x}}\mathrm{S}{\mathrm{r}}_{\mathrm{x}}\mathrm{Cu}{\mathrm{O}}_4$ single crystals at various doping levels x and compare the results with theoretical predictions obtained assumi…
