  "abstract": "Using $e^+e^-$ annihilation data corresponding to an integrated luminosity of 4.5 fb$^{-1}$ collected with the BESIII detector at center-of-mass energies between 4.600 and 4.699 GeV, the first amplitude analysis of the charmed baryon decay $Λ_c^+ \\to p K_S^0 π^0$ is performed. The processes $Λ_c^+ \\to p \\bar{K}^{*}(892)^0$, $Λ_c^+ \\to Δ(1600)^+ K_S^0$, and $Λ_c^+ \\to N(1710)^+ K_S^0$ are identified with statistical significances of $12.8σ$, $14.5σ$, and $6.2σ$, respectively. The mass and width of $Δ(1600)^+$ are measured to be $(1520.4 \\pm 8.8 \\pm 37.7)~\\text{MeV}$ and $(199.4 \\pm 26.4 \\pm 39.9)~\\text{MeV}$, respectively. The mass and width of $N(1710)^+$ are measured to be $(1719.7 \\pm 9.4 \\pm 9.1)~\\text{MeV}$ and $(72.0 \\pm 18.0 \\pm 15.0)~\\text{MeV}$, respectively. The branching fractions of these processes are determined to be $\\mathcal{B}[Λ_c^+ \\rightarrow Δ(1600)^+ (\\rightarrow p π^0) K_S^0] = (8.10 \\pm 0.80 \\pm 5.57) \\times 10^{-3}$, $\\mathcal{B}[Λ_c^+ \\rightarrow N(1710)^+ (\\rightarrow p π^0) K_S^0] = (1.58 \\pm 0.48 \\pm 0.77) \\times 10^{-3}$, and $\\mathcal{B}[Λ_c^+ \\rightarrow p \\bar{K}^{*}(892)^0 (\\rightarrow K_S^0 π^0)] = (2.63 \\pm 0.47 \\pm 0.29) \\times 10^{-3}$, where the first uncertainties are statistical and the second systematic.",
