Inelastic neutron scattering on Ce pyrochlores: Signatures of electric monopoles

Pengwei Zhao, Gang V. Chen

We revisit the pyrochlore spin liquid materials Ce $_{2}$ Sn $_{2}$ O $_{7}$ and Ce $_{2}$ Zr $_{2}$ O $_{7}$ by examining the existing experiments. We continue to rely on the special properties of the…

Emergent Berezinskii-Kosterlitz-Thouless and Kugel-Khomskii physics in the triangular lattice bilayer colbaltate

Gang V. Chen

Motivated by the experiments on the triangular lattice bilayer colbaltate K $_{2}$ Co $_{2}$ (SeO $_{3}$ ) $_{3}$ , we formulate a theory to explore the underlying physics from a couple observatio…
