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…
Thermodynamics of Shastry-Sutherland Model under Magnetic Field
Menghan Song, Chengkang Zhou, Cheng Huang +1
Motivated by the recent experimental discovery of the -linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu(BO), we perform the…
T-linear specific heat in pressurized and magnetized Shastry-Sutherland Mott insulator SrCu2(BO3)2
Jing Guo, Pengyu Wang, Cheng Huang +13
The pressurized Shastry-Sutherland Mott insulator SrCu2(BO3)2 has been found to host a plaquette-singlet phase and an antiferromagnetic phase that break different symmetries sponta…
Spectroscopic evidences for the spontaneous symmetry breaking at the deconfined critical point of - model
Shutao Liu, Yan Liu, Chengkang Zhou +5
Recent numerical and theoretical studies on the two-dimensional - model suggests that the deconfined quantum critical point is actually a -symmetry-enhanced first-or…
Spin excitations arising from anisotropic Dirac spinons in YCu(OD)Br[Br(OD)]
Lankun Han, Zhenyuan Zeng, Min Long +10
A Dirac quantum spin liquid hosts Dirac spinons, which are low-energy fractionalized neutral quasiparticles with spin 1/2 that obey the Dirac equation. Recent inelastic neutron sca…
