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…
Intertwined dipolar and multipolar order in the triangular-lattice magnet TmMgGaO
Yao Shen, Changle Liu, Yayuan Qin +6
A phase transition is often accompanied by the appearance of an order parameter and symmetry breaking. Certain magnetic materials exhibit exotic hidden-order phases, in which the o…
Extended Coulomb liquid of paired hardcore boson model on a pyrochlore lattice
Chun-Jiong Huang, Changle Liu, Ziyang Meng +3
There is a growing interest in the Coulomb liquid in both quantum materials in pyrochlore ice and cluster Mott insulators and cold atom systems. We explore a paired hardcore…
Selective measurements of intertwined multipolar orders: non-Kramers doublets on a triangular lattice
Chang-Le Liu, Yao-Dong Li, Gang Chen
Motivated by the rapid experimental progress on the spin-orbit-coupled Mott insulators, we propose and study a generic spin model that describes the interaction between the non-Kra…
