Tuning the confinement potential between spinons in the Ising chain CoNb2O6 using longitudinal fields and quantitative determination of the microscopic Hamiltonian
Leonie Woodland, David Macdougal, Ivelisse M. Cabrera +4
The Ising chain realizes the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two domain walls (spinons) that can separate apart at no energy c…
Avoided quasiparticle decay and enhanced excitation continuum in the spin-1/2 near-Heisenberg triangular antiferromagnet Ba3CoSb2O9
David Macdougal, Stephanie Williams, Dharmalingam Prabhakaran +3
We explore the magnetic excitations of the spin-1/2 triangular antiferromagnet Ba3CoSb2O9 in its 120 degree ordered phase using single-crystal high-resolution inelastic neutron sca…
Spin dynamics of coupled spin ladders near quantum criticality in Ba2CuTeO6
David Macdougal, Alexandra S. Gibbs, Tao Ying +6
We report inelastic neutron scattering measurements of the magnetic excitations in Ba2CuTeO6, proposed by ab initio calculations to magnetically realize weakly coupled antiferromag…
