An anisotropic spin model of strong spin-orbit-coupled triangular antiferromagnets
Yao-Dong Li, Xiaoqun Wang, Gang Chen
Motivated by the recent experimental progress on the strong spin-orbit-coupled rare earth triangular antiferromagnet, we analyze the highly anisotropic spin model that describes th…
Quantum spin ice on the breathing pyrochlore lattice
Lucile Savary, Xiaoqun Wang, Hae-Young Kee +3
The Coulombic quantum spin liquid in quantum spin ice is an exotic quantum phase of matter that emerges on the pyrochlore lattice and is currently actively searched for. Motivated…
Rare-earth triangular lattice spin liquid: a single-crystal study of YbMgGaO
Yuesheng Li, Gang Chen, Wei Tong +5
YbMgGaO, a structurally perfect two-dimensional triangular lattice with odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 local moments of Yb$…
Cluster Mott insulators and two Curie-Weiss regimes on an anisotropic Kagome lattice
Gang Chen, Hae-Young Kee, Yong Baek Kim
Motivated by recent experiments on the quantum-spin-liquid candidate material LiZn2Mo3O8, we study a single-band extended Hubbard model on an anisotropic Kagome lattice with the 1/…
Coulomb liquid phases of bosonic cluster Mott insulators on a pyrochlore lattice
Jian-Ping Lv, Gang Chen, Youjin Deng +1
Employing large-scale quantum Monte Carlo simulations, we reveal the full phase diagram of the extended Hubbard model of hard-core bosons on the pyrochlore lattice with partial fil…
Synthetic gauge fields stabilize a chiral spin liquid phase
Gang Chen, Kaden R. A. Hazzard, Ana Maria Rey +1
We calculate the phase diagram of the SU() Hubbard model describing fermionic alkaline earth atoms in a square optical lattice with on-average one atom per site, using a slave-r…
