Fig. 2: Occurrence of d-s wave transition.
From: Charge stripe manipulation of superconducting pairing symmetry transition
DQMC-calculated \({\bar{P}}_{\alpha }\) as a function of δ at T = t/5 and U/t = 4 with \({{\mathcal{P}}}=3\) on a L = 12 lattice for (a) V0=0, (b) V0=3, (c) V0=4, and (d) V0=8. Here, we divided the data into 10 bins and calculated the error of the data using the jackknife method. The horizontal dashed line represents the zero point on the y-axis. e DMRG-calculated effective zero-momentum pair-pair structure factor \({\bar{S}}_{\alpha }\) as a function of V0 at δ=0.111 and U/t = 8 on the 6 × 6 cylinder. While a small discrepancy is observed, it will not affect our conclusion within small error bars. (f) DMRG-calculated V0,c for d-s wave transition with different U on both 6 × 3 and 6 × 6 cylinders, exhibiting a nearly linear function of U. For comparison, DQMC result on a 12 × 12 lattice at U/t  = 4 and T  = t/5 is also marked here.
