Low-temperature dynamical structure factor of the two-leg spin-1/2 Heisenberg ladder by Goetze, W, Karahasanovic, U, Essler, F

“…We determine the dynamical structure factor of the two-leg spin- 1 2 Heisenberg ladder at low temperatures in the regime of strong rung coupling. …”

Fate of spinons in spontaneously dimerized spin-(1)/(2) ladders by Allen, D, Essler, F, Nersesyan, A

“…We study a weakly coupled, frustrated two-leg spin-1/2 Heisenberg ladder. For vanishing coupling between the chains, elementary excitations are deconfined, gapless spin-1/2 objects called spinons. …”

Finite temperature dynamical structure factors of low dimensional strongly correlated systems by Goetze, W, Wolf Goetze

“…We determine the dynamical structure factors of two gapped correlated electron systems, namely the Ising model in a strong transverse field and the two-leg spin-1/2 Heisenberg ladder in the limit of strong rung coupling. …”
