论文摘要
数十年来，在广泛的材料科学和量子信息领域中，搜索三胞胎超导性已被密切追求。然而，这些新颖的状态仍然很少见。在简化有效的三轨模型中，我们通过使用有限温度确定性量子蒙特卡洛方法和基态约束量子量子蒙特卡洛方法来揭示掺杂的MOS $ _2 $中的自旋三重态配对。在$ \ avg {n} = 0.60-0.80 $的宽填充区域中，费用中立性$ \ avg {n} = 2/3 $，$ f $ - 波配对比其他对称性占主导地位。随着现场库仑相互作用的增加，配对的敏感性强烈增加，并且对自旋轨道耦合不敏感。
Searching 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 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 $\avg{n}=0.60-0.80$ around charge neutrality $\avg{n}=2/3$, 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.
