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…
Symmetries of the Resistance of Mesoscopic Samples in the Quantum Hall Regime
E. Peled, Y. Chen, E. Diez +4
The symmetry properties of the resistance of mesoscopic samples in the quantum Hall regime are investigated. In addition to the reciprocity relation, our samples obey new symmetrie…
Dynamics of an anisotropic Haldane antiferromagnet in strong magnetic field
A. Zheludev, S. M. Shapiro, Z. Honda +8
We report the results of elastic and inelastic neutron scattering experiments on the Haldane gap quantum antiferromagnet Ni(C5D14N2)2N3(PF6) performed at mK temperatures in a wide…
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…
