[Diffusion Raman électronique dans des oxydes de cuivre supraconducteurs : Comprendre le diagramme de phase]
Des mesures de diffusion Raman électronique ont été menées sur les oxydes de cuivre supraconducteurs dopés en trous en fonction de la température et du dopage. Dans lʼétat supraconducteur du régime sous dopé, le poids spectral des quasiparticules de Bogoliubov reste important dans les regions nodales alors quʼil est réduit dans les regions antinodales. On peut alors définir la fraction cohérente de la surface de Fermi,
Electronic Raman scattering measurements have been performed on hole doped copper oxide (cuprate) superconductors as a function of temperature and doping level. In the superconducting state, coherent Bogoliubov quasiparticles develop preferentially over the nodal region in the underdoped regime. We can then define the fraction of coherent Fermi surface,
