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…
Quantum Fisher Information as a Probe of Critical Scaling in Frustrated Magnets: Signatures from Kagome Quantum Spin Liquid
Zhengbang Zhou, Chengkang Zhou, Menghan Song +2
Quantum Fisher information (QFI) is a measure of multipartite quantum entanglement that can be obtained from inelastic neutron scattering data on quantum magnets. In this work, we…
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…
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…
