“…Mathematically, a full description of a large spin (≥ 1) involves not only rank-1 spin-vectors, but also high-rank spin-tensors, therefore it is expected that the resulting quantum magnetism may possess both spin-vector and tensor orders. So far, spin-vector magnetism of a strongly correlated spin-1 chain has been extensively studied, where the competition between spin interaction and Zeeman field (either uniform or spiral along the chain) leads to rich phase diagrams [34][35][36][37][38][39][40]. Certain nematic magnetic orders of spin-tensors (with vanishing spin-vector) have been investigated in 2D geometrically frustrated (e.g., triangle) lattices [41][42][43][44][45][46][47][48][49].…”

The characterization of quantum magnetism in a large spin (≥ 1) system naturally involves both spin-vectors and -tensors. While certain types of spin-vector (e.g., ferromagnetic, spiral) and spintensor (e.g., nematic in frustrated lattices) orders have been investigated separately, the coexistence and correlation between them have not been well explored. Here we propose and characterize a novel quantum spiral spin-tensor order on a spin-1 Heisenberg chain subject to a spiral spin-tensor Zeeman field, which can be experimentally realized using a Raman-dressed cold atom optical lattice. Through numerical density-matrix renormalization group (DMRG) simulation, we obtain the phase diagram and characterize the coexistence of spin-vector and spin-tensor orders as well as their correlations. Our results may open an avenue for exploring novel magnetic orders and spin-tensor electronics/atomtronics in large-spin systems.
