Bosonic Spectral Function and the Electron-Phonon Interaction in HTSC Cuprates

Figure 7

Experimental (solid lines) and calculated (dashed lines) data of 𝑅(𝜔) in optimally doped YBCO [105] at 𝑇=100,200,300K (from top to bottom). Inset: the two (solid and dashed lines) reconstructed 𝛼^2tr(𝜔)𝐹(𝜔)’s at 𝑇=100K. The phonon density of states 𝐹(𝜔)—dotted line in the inset. From [33–35].
