Quantum criticality in an Ising chain: experimental evidence for emergent E8 symmetry
R. Coldea, D. A. Tennant, E. M. Wheeler +6
Quantum phase transitions take place between distinct phases of matter at zero temperature. Near the transition point, exotic quantum symmetries can emerge that govern the excitati…
Spin dynamics of frustrated easy-axis triangular antiferromagnet 2H-AgNiO2 explored by inelastic neutron scattering
E. M. Wheeler, R. Coldea, E. Wawrzynska +6
We report inelastic neutron scattering measurements of the spin dynamics in the layered hexagonal magnet 2H-AgNiO2 which has stacked triangular layers of antiferromagnetically-coup…
Charge disproportionation and collinear magnetic order in the frustrated triangular antiferromagnet AgNiO2
E. Wawrzynska, R. Coldea, E. M. Wheeler +5
We report a high-resolution neutron diffraction study of the crystal and magnetic structure of the orbitally-degenerate frustrated metallic magnet AgNiO2. At high temperatures the…
Orbital degeneracy removed by charge order in triangular antiferromagnet AgNiO2
E. Wawrzynska, R. Coldea, E. M. Wheeler +6
We report a high-resolution neutron diffraction study on the orbitally-degenerate spin-1/2 hexagonal antiferromagnet AgNiO2. A structural transition to a tripled unit cell with exp…
