Magnetic Excitations in Bilayer High-Temperature Superconductors with Stripe Correlations
G. S. Uhrig, K. P. Schmidt, M. Grüninger
The universal behaviour of the magnetic excitations in high-temperature superconductors is described in a model with static stripes retaining only the localized spin degrees of fre…

Unifying Magnons and Triplons in Stripe-Ordered Cuprate Superconductors
G. S. Uhrig, K. P. Schmidt, M. Grüninger
Based on a two-dimensional model of coupled two-leg spin ladders, we derive a unified picture of recent neutron scattering data of stripe-ordered La_(15/8)Ba_(1/8)CuO_4, namely of…
