The S=1/2 chain in a staggered field: High-energy bound-spinon state and the effects of a discrete lattice
M. Kenzelmann, C. D. Batista, Y. Chen +4
We report an experimental and theoretical study of the antiferromagnetic S=1/2 chain subject to uniform and staggered fields. Using inelastic neutron scattering, we observe a novel…

Bound spinons in an antiferromagnetic S=1/2 chain with a staggered field
M. Kenzelmann, Y. Chen, C. Broholm +2
Inelastic neutron scattering was used to measure the magnetic field dependence of spin excitations in the antiferromagnetic S=1/2 chain CuCl_2 2(dimethylsulfoxide) (CDC) in the pre…

Two-magnon states in Cu(NO3)2*2.5D2O using inelastic neutron scattering
D. A. Tennant, C. Broholm, Daniel H. Reich +6
We report measurements of the two-magnon states in a dimerized antiferromagnetic chain material, copper nitrate (\QTR{group}{Cu(NO)DO}). Using inelastic…
