DESCRIPTION:The unambiguous experimental confirmation of a quantum spin li
 quid remains a longstanding issue in modern condensed matter physics. In p
 articular\, significant efforts have been made to realize quantum spin ice
 \, a three-dimensional quantum spin liquid that provides a lattice realiza
 tion of quantum electrodynamics and hosts emergent photons as well as gapp
 ed spinon excitations. Recent experiments on Ce-based dipolar-octupolar py
 rochlore systems\, Ce2Zr2O7 and Ce2Sn2O7\, suggest that these materials ma
 y host the so-called π-flux quantum spin ice. We will first discuss the t
 heoretical background for quantum spin ice and present our recent theoreti
 cal results on the dipolar-octupolar quantum spin ice states. Then we will
  compare our theoretical predictions on dynamical properties of spinons an
 d emergent photons with recent experimental results.
