Bound states in weakly disordered spin ladders
M. Arlego, W. Brenig, D. C. Cabra +3
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 couple…

Bond-impurity induced bound states in disordered spin-1/2 ladders
M. Arlego, W. Brenig, D. C. Cabra +3
We discuss the effect of weak bond-disorder in two-leg spin ladders on the dispersion relation of the elementary triplet excitations with a particular focus on the appearance of bo…
