Topological phase transition between distinctWeyl semimetal states in MoTe2
Anmin Zhang, Xiaoli Ma, Changle Liu +10
We present experimental evidence of an intriguing phase transition between distinct topological states in the type-II Weyl semimetal MoTe2. We observe anomalies in the Raman phonon…
Experimental identification of electric dipoles induced by magnetic monopoles in Tb2Ti2O7
Feng Jin, Changle Liu, Anmin Zhang +4
The fundamental principles of electrodynamics allow an electron carrying both electric monopole (charge) and magnetic dipole (spin) but prohibit its magnetic counterpart. Recently…
Anisotropic magnetic excitations of a frustrated bilinear-biquadratic spin model -- Implications for spin waves of detwinned iron pnictides
Changle Liu, Xingye Lu, Pengcheng Dai +2
Elucidating the nature of spin excitations is important to understanding the mechanism of superconductivity in the iron pnictides. Motivated by recent inelastic neutron scattering…
Intrinsic quantum Ising model on a triangular lattice magnet TmMgGaO and beyond
Changle Liu, Chun-Jiong Huang, Gang Chen
The rare-earth magnet TmMgGaO is proposed to be an intrinsic quantum Ising magnet described by the antiferromagnetic transverse field Ising model (TFIM) on a triangular latti…
Upper branch magnetism in quantum magnets: Collapses of excited levels and emergent selection rules
Changle Liu, Fei Ye Li, Gang Chen
In many quantum magnets especially the rare-earth ones, the low-lying crystal field states are not well separated from the excited ones and thus are insufficient to describe the lo…
Interplay of Dirac electrons and magnetism in AMnBi2 (A=Ca, Sr)
Anmin Zhang, Changle Liu, Changjiang Yi +8
Dirac materials exhibit intriguing low-energy carrier dynamics that offer a fertile ground for novel physics discovery. Of particular interest is the interplay of Dirac carriers wi…
