Thermal conductivity of quantum magnetic monopoles in the frustrated pyrochlore Yb2Ti2O7

Y. Tokiwa, T. Yamashita, M. Udagawa +8

We report low-temperature thermal conductivity $\kappa$ of pyrochlore Yb${}_2$Ti${}_2$O${}_7$, which contains frustrated spin-ice correlations with significant quantum fluctuations. In the di…
