Abstract
The search for triplet superconductivity has been pursued intensively in a broad field of material science and quantum information for decades. Nevertheless, these novel states remain rare. Within a simplified effective three-orbital model, we reveal a spin triplet pairing in doped ${\mathrm{MoS}}_{2}$ by employing both the finite-temperature determinant quantum Monte Carlo approach and the ground-state constrained-phase quantum Monte Carlo method. In a wide filling region of $\ensuremath{\langle}n\ensuremath{\rangle}=0.60$--0.80 around charge neutrality $\ensuremath{\langle}n\ensuremath{\rangle}=2/3$, the $f$-wave pairing dominates over other symmetries. The pairing susceptibility strongly increases as the on-site Coulomb interaction increases, and it is insensitive to spin-orbit coupling.
