Fractional and Integer Excitations in Quantum Antiferromagnetic Spin 1/2 Ladders
C. Knetter, K. P. Schmidt, M. Grüninger +1
Spectral densities are computed in unprecedented detail for quantum antiferromagnetic spin 1/2 two-leg ladders. These results were obtained due to a major methodical advance achiev…

Observation of two-magnon bound states in the two-leg ladders of (Ca,La)14Cu24O41
M. Windt, M. Grueninger, T. Nunner +8
Phonon-assisted 2-magnon absorption is studied at T=4 K in the spin-1/2 two-leg ladders of Ca_14-x La_x Cu_24 O_41 (x=5 and 4) for polarization of the electrical field parallel to…
