Symmetric and asymmetric excitations of a strong-leg quantum spin ladder

D. Schmidiger, P. Bouillot, G. Ehlers +5

The zero-field excitation spectrum of the strong-leg spin ladder (C${}_7$H${}_{1}0$N)${}_2$CuBr${}_4$ (DIMPY) is studied with a neutron time-of-flight technique. The spectrum is decomposed i…
