Spectroscopic signatures of fractionalization in octupolar quantum spin ice

Félix Desrochers, Yong Baek Kim

Recent investigations on the dipolar-octupolar compounds Ce${}_2$Zr${}_2$O${}_7$ and Ce${}_2$Sn${}_2$O${}_7$ suggest that they may stabilize so-called $\pi$-flux octupolar quantum spin ice ($\pi$-…
