Search for Emergent Photon Excitation in Pr Based Quantum Spin Ice Candidates

Abstract: By introducing transvers terms in the effective spin-1/2 Hamiltonian on the pyrochlore lattice, the quantum spin ice (QSI) state, a special quantum spin liquid whose emergent properties can be described by a U(1)-gauge theory, may be realized. Numerical simulations based on QSI model have predicted the emergence of novel collective excitations such as artificial photons which is gapless with linear dispersion at low energy. However, a convincing realization of the quantum spin ice state in real materials has not been achieved so far, for instance, experimental evidence of gapless photons excitations in these materials has not been found. Our preliminary investigations have indicated that both Pr2Ir2O7 and Pr2Hf2O7 are likely realizations of QSI. The aim of the proposed experiments is to search for emergent photons excitations in these two samples at LET.
