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…
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 Fisher Information as a Thermal Probe in Frustrated Magnets through Insights from Quantum Spin Ice
Chengkang Zhou, Zhengbang Zhou, Félix Desrochers +2
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 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,…
Magnetic Field Response of Dipolar-Octupolar Quantum Spin Ice
Zhengbang Zhou, Félix Desrochers, Yong Baek Kim
Dipolar-octupolar (DO) pyrochlore systems Ce(Zr,Sn,Hf)O have garnered much attention as recent investigations suggest that they may stabilize a novel quantum spin ice (…
Emergent photons and fractionalized excitations in a quantum spin liquid
Bin Gao, Félix Desrochers, David W. Tam +6
A quantum spin liquid (QSL) arises from a highly entangled superposition of many degenerate classical ground states in a frustrated magnet, and is characterized by emergent gauge f…
Quantum Fluctuations Suppress the Critical Fields in BaCo(AsO)
Shiva Safari, William Bateman-Hemphill, Asimpunya Mitra +10
Early efforts to realize exotic quantum ground states in frustrated magnets focused on frustration arising from the lattice geometry alone. Attention has shifted to bond-dependent…
Finite Temperature Dynamics in 0-Flux and -Flux Quantum Spin Ice: Self-Consistent Exclusive Boson Approach
Félix Desrochers, Yong Baek Kim
Quantum spin ice (QSI) is an emblematic three-dimensional quantum spin liquid (QSL) on the pyrochlore lattice that hosts gapless photon-like modes and spinon excitations. De…
A pseudofermion functional renormalization group study of dipolar-octupolar pyrochlore magnets
Li Ern Chern, Félix Desrochers, Yong Baek Kim +1
Motivated by recent experiments on CeZrO that reveal a dynamic, liquid-like ground state, we study the nearest neighbor XYZ Hamiltonian of dipolar-octupolar pyrochlore…
