Query: The Spectral Periodicity of Spinon Continuum in Quantum Spin Ice   Motivated by the rapid experimental progress of quantum spin ice materials,
we study the dynamical properties of pyrochlore spin ice in the U(1) spin
liquid phases. In particular, we focus on the spinon excitations that appear at
high energies and show up as an excitation continuum in the dynamic spin
structure factor. The keen connection between the crystal symmetry
fractionalization of the spinons and the spectral periodicity of the spinon
continuum is emphasized and explicitly demonstrated. When the spinon
experiences a background $\pi$ flux and the spinon continuum exhibits an
enhanced spectral periodicity with a folded Brillouin zone, this spectral
property can then be used to detect the spin quantum number fractionalization
and U(1) spin liquid. Our prediction can be immediately examined by inelastic
neutron scattering experiments among quantum spin ice materials with Kramers'
doublets. Further application to the non-Kramers' doublets is discussed.
