In a recent letter, Pothuizen et al. reported angle-resolved photoemission data on the single-layer insulating cuprate Sr_2CuO_2Cl_2. This comment addresses the issue whether it is possible to deduce an accurate value for the O 2p hopping integral $t

The one-dimensional (1D) $t$-$J$ Holstein model is studied by exact diagonalization of finite rings using a variational approximation for the phonon states. Due to renormalization effects induced by the phonons, for intermediate electron-phonon coupl

An analysis of angle-resolved photoemission (ARPES) experiments in the superconducting state of the high \tc copper-oxides is presented. It is based on a phenomenological weak-coupling BCS model which incorporates the experimental normal state disper

We consider the effect of non-magnetic impurities in a $d_{x^2 - y^2}$ superconductor with $\ef$ close to a van Hove singularity. It is shown that the non-trivial density of states (DOS) allows for resonant scattering already at intermediate potentia

The optical conductivity of the CuO$_3$-chains, a subsystem of the 1-2-3 materials, is dominated by a broad peak in the mid-infrared ($\omega \approx 0.2$eV), and a slowly falling high-frequency tail. The 1D $t$-$J$-model is proposed as the relevant

Wenn Jugendliche nicht in das bestehende System passen, werden sie gerne als „SystemsprengerInnen“, „VerweigererInnen“ oder „Problemjugendliche“ bezeichnet. In der Diskussion um diese Jugendlichen geht es meistens um die hohen Kosten, die
