Thermodynamic Spectroscopy of Emergent Excitations in Quantum Spin Ice
Zhengbang Zhou, Tony An, Yong Baek Kim
Quantum spin ice (QSI) is a three-dimensional quantum spin liquid where fractionalized spinons interact with emergent photons. The XXZ model on the pyrochlore lattice realizes such…
Quantum Fisher Information as a Thermal Probe in Frustrated Magnets through Insights from Quantum Spin Ice
Chengkang Zhou, Zhengbang Zhou, Félix Desrochers +3
Quantum Fisher information (QFI) is a measure of multipartite entanglement accessible via inelastic neutron scattering. Here we demonstrate that QFI reveals thermal and dynamical p…
Spectroscopic Demarcation of Emergent Photons and Spinons in a Dipolar-Octupolar Quantum Spin Liquid
Bin Gao, Zhengbang Zhou, Tingjun Zhang +4
The identification of fractionalized excitations in quantum spin liquids (QSLs) remains a central challenge in condensed matter physics. In dipolar-octupolar (DO) pyrochlores, such…
Quantum Spin Liquids in Pyrochlore Magnets With Non-Kramers Local Moments
Tony An, Félix Desrochers, Yong Baek Kim
Numerous experiments on pyrochlore oxides Pr(Zr, Sn, Hf, Ir)O with non-Kramers Pr ions suggest that they support a quantum spin liquid (QSL) ground state, but th…
Towards a global phase diagram of Ce-based dipolar-octupolar pyrochlore magnets under magnetic fields
Zhengbang Zhou, Yong Baek Kim
Recent experiments have established a strong case for Ce(Zr, Sn, Hf)O to host -flux quantum spin ice (QSI). However, an irrefutable conclusion still requires strong…
