Perfectly hidden order and Z2 confinement transition in a fully packed monopole liquid
Attila Szabo, Santiago A. Grigera, P. C. W. Holdsworth +5
We investigate a variant of spin ice whose degenerate ground states are densely packed monopole configurations. An applied field drives this model through a Z2 confinement transiti…
Neutron scattering from fragmented frustrated magnets
F. Museur, E. Lhotel, P. C. W. Holdsworth
The fragmentation description is used to analyse calculated neutron scattering intensities from kagomé ice and spin ice systems. The longitudinal, transverse and harmonic fragments…
Emergent tri-criticality in magnetic metamaterials
Björn Erik Skovdal, Gunnar K. Pálsson, P. C. W. Holdsworth +1
Metallic discs engineered on the 100 nm scale have an internal magnetic texture which varies from a fully magnetized state to a vortex state with zero moment. The interplay between…
Violation of the fluctuation-dissipation theorem and effective temperatures in spin ice
Valentin Raban, Ludovic Berthier, Peter C. W. Holdsworth
We present numerical tests of the fluctuation-dissipation theorem (FDT) in the dumbbell model of spin ice with parameters suitable for dysprosium titanate. The tests are made for l…
Fragmentation in Frustrated Magnets -- A review
E. Lhotel, L. D. C. Jaubert, P. C. W. Holdsworth
Spin liquids are exotic phases of matter that often support emergent gauge fields and quasi-particle excitations. While spin liquids are commonly known for remaining disordered, th…
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…
