Coherent spin waves in a maximal entropy phase

Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24

In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…

Dipolar-octupolar correlations and hierarchy of exchange interactions in Ce $_{2}$ Hf $_{2}$ O $_{7}$

Victor PorÃ©e, Anish Bhardwaj, Elsa Lhotel +9

High-resolution neutron spectroscopy on Ce $_{2}$ Hf $_{2}$ O $_{7}$ reveals a correlated state characterized by distinct dipolar scattering signals -- quasi-elastic and inelastic contributio…

Thermodynamics of the dipole-octupole pyrochlore magnet Ce $_{2}$ Hf $_{2}$ O $_{7}$ in applied magnetic fields

The recently discovered dipole-octupole pyrochlore magnet Ce $_{2}$ Hf $_{2}$ O $_{7}$ is a promising three-dimensional quantum spin liquid candidate which shows no signs of ordering at low t…

Fractional matter coupled to the emergent gauge field in a quantum spin ice

Electronic spins can form long-range entangled phases of condensed matter named quantum spin liquids. Their existence is conceptualized in models of two- or three-dimensional frust…
