Two component dynamics of the superconducting order parameter revealed by time-resolved Raman scattering

R. P. Saichu, I. Mahns, A. Goos +10

We study the dynamics of the superconducting order parameter in the high- $T_{c}$ cuprate Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 - I^´}$ by employing a novel time-resolved pump-probe Raman experiment…

Direct observation of room temperature high-energy resonant excitonic effects in graphene

I. Santoso, P. K Gogoi, H. B. Su +14

Using a combination of ultraviolet-vacuum ultraviolet reflectivity and spectroscopic ellipsometry, we observe a resonant exciton at an unusually high energy of 6.3eV in epitaxial g…
