0 N ov 2 00 4 Bound states in weakly disordered spin ladders
We study the appearance of bound states in the spin gap of spin-1/2 ladders induced by weak bond disorder. Starting from the strong-coupling limit, i.e., the limit of weakly coupled dimers, weExpand
Magnetic heat conductivity in $\rm\bf CaCu_2O_3$: linear temperature dependence
We present experimental results for the thermal conductivity $\kappa$ of the pseudo 2-leg ladder material $\rm CaCu_2O_3$. The strong buckling of the ladder rungs renders this material a goodExpand
