We investigate the two-dimensional t–J model at a hole doping of \({\bar{n}}_{{\rm{h}}}=1/8\) using recently developed high accuracy fermionic projected entangled pair states method. By applying the stochastic gradient descent method combined with the Monte Carlo sampling technique, we obtain the ground state hole energy E_hole = −1.621 for J/t = 0.4. We show that the ground state has stable diagonal stripes instead of vertical stripes with a width of 4 unit cells, and stripe filling ρ_l = 0.5. We further show that the long-range superconductivity order is suppressed at this point.

根据fPEPS计算，在n – h = 1/8掺杂的t – J模型中稳定的斜条纹

我们使用最近开发的高精度铁电投影纠缠对态研究了在空穴掺杂为\（{\ bar {n}} _ {{\ rm {h}}} = 1/8 \）的二维t - J模型方法。通过应用随机梯度下降法与蒙特卡洛采样技术相结合， 对于J / t  = 0.4 ，我们获得了基态空穴能量E _hole = -1.621 。我们表明，基态具有稳定的斜条纹，而不是与4的单元电池的宽度垂直条纹，和条纹填充ρ_升 = 0.5。我们进一步表明，在这一点上，远程超导阶被抑制了。
