S=½ chain in a staggered field: high-energy bound-spinon state and the effects of a discrete lattice
(American Physical Society, 2005-03-01)
We report an experimental and theoretical study of the antiferromagnetic S=½ chain subject to uniform and staggered fields. Using inelastic neutron scattering, we observe a bound-spinon state at high energies in the linear ...
Bound spinons in an antiferromagnetic S=1/2 chain with a staggered field
(American Physical Society, 2004-07-02)
Inelastic neutron scattering was used to measure the magnetic field dependence of spin excitations in the antiferromagnetic S=1/2 chain CuCl2·2(dimethylsulfoxide) in the presence of uniform and staggered fields. Dispersive ...
