We investigate the spin $S=1/2$ Heisenberg model on the body centered cubic lattice in the presence of ferromagnetic and antiferromagnetic nearest-neighbor $J_{1}$, second-neighbor $J_{2}$, and third-neighbor $J_{3}$ exchange interactions. The classical ground state phase diagram obtained by a Luttinger-Tisza analysis is shown to host six different (noncollinear) helimagnetic orders in addition to ferromagnetic, N\'eel, stripe and planar antiferromagnetic orders. Employing the pseudofermion…

Classical spiral spin liquids as a possible route to quantum spin liquids.
TLDR
The pseudofermion functional renormalization group (PFFRG) technique is employed to investigate the effects of quantum fluctuations when the classical spins are replaced by quantum $S=1/2$ spins and finds that extended spiral spin-liquid regimes change into paramagnetic quantum phases possibly realizing quantum spin liquids.

TLDR
It is shown that for the triangular lattice dipolar Heisenberg model, a robust quantum paramagnetic phase exists in a surprisingly wide region, θ∈[0,54°), for dipoles tilted along the lattice diagonal direction, points to a promising direction to search for quantum spin liquids in ultracold dipolar molecules.
