High-temperature superconductivity in the copper-oxide ceramics remains an unsolved problem because we do not know what the propagating degrees of freedom are in the …

The optical conductivity spectrum of Sr 1 4− x Ca x Cu 24 O 41, composed of two-leg Cu 2 O 3 ladders and edge-sharing CuO 2 chains, is investigated on single crystals with various …
We use a variational approach to gain insight into the strongly correlated d-wave superconducting state of the high T c cuprates at T= 0. We show that strong correlations lead …
Starting with the three-band extended Hubbard model (or dp model) widely used to represent the CuO 2 planes in the high-T c cuprates, we make a systematic reduction to an …
