Quantum Spin Supersolid as a precursory Dirac Spin Liquid in a Triangular Lattice Antiferromagnet

Haichen Jia, Bowen Ma, Zidan Wang +1

Based on the recent experiments on the triangular lattice antiferromagnet Na${}_2$BaCo(PO${}_4$)${}_2$, we propose the easy-axis XXZ spin-1/2 model on the triangular lattice, that exhibi…
