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…
Excitations of quantum Ising chain CoNb2O6 in low transverse field: quantitative description of bound states stabilized by off-diagonal exchange and applied field
Leonie Woodland, Izabella Lovas, M. Telling +3
We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNbO…
High-energy spin waves in the spin-1 square-lattice antiferromagnet LaNiO
A. N. Petsch, N. S. Headings, D. Prabhakaran +5
Inelastic neutron scattering is used to study the magnetic excitations of the square-lattice antiferromagnet LaNiO. We find that the spin waves cannot be described by…
Order-by-Disorder from Bond-Dependent Exchange and Intensity Signature of Nodal Quasiparticles in a Honeycomb Cobaltate
M. Elliot, P. A. McClarty, D. Prabhakaran +4
Recent theoretical proposals have argued that cobaltates with edge-sharing octahedral coordination can have significant bond-dependent exchange couplings thus offering a platform i…
Fragmented monopole crystal, dimer entropy and Coulomb interactions in DyIrO
V. Cathelin, E. Lefrançois, J. Robert +12
Neutron scattering, specific heat and magnetisation measurements on both powders and single crystals reveal that DyIrO realizes the fragmented monopole crystal state in…
Quantum oscillations probe the Fermi surface topology of the nodal-line semimetal CaAgAs
Y. H. Kwan, P. Reiss, Y. Han +6
Nodal semimetals are a unique platform to explore topological signatures of the unusual band structure that can manifest by accumulating a nontrivial phase in quantum oscillations.…
