Abstract
We investigate the 2D t-J model at a hole doping of =1/8 using recently developed high accuracy fermionic projected entangled pair states(fPEPS) method. By applying stochastic gradient descent method combined with Monte Carlo sampling technique, we obtain the ground state hole energy =-1.6186 for =0.4. We show that the ground state has stable diagonal stripes instead of vertical stripes with width of 4 unit cells, and stripe filling =0.5. We further show that the long range superconductivity order is suppressed at this point.
