Doping induced charge redistribution in the high temperature superconductor HgBa2CuO4
P. Süle, C. Ambrosch-Draxl, H. Auer +1
To understand the link between doping and electronic properties in high temperature superconductors, we report first-principles calculations on the oxygen doping effect for the sin…

Charge kinks as Raman scatterers in quarter-filled ladders
E. Ya. Sherman, C. Ambrosch-Draxl, P. Lemmens +2
Charge kinks are considered as fundamental excitations in quarter-filled charge-ordered ladders. The strength of the coupling of the kinks to the three-dimensional lattice depends…
