Anisotropic transport in the overdoped High-Tc superconductors within the Van Hove scenario

Belen Valenzuela, Maria A. H. Vozmediano

Recent Raman experiments [F. Venturini et al., Phys. Rev. Lett. {\bf 89}, 107003-1,(2002)] done in $B{i}_{2}S{r}_{2}CaC{u}_2{O}_4$ have found that antinodal quasiparticles become insulatin…
