Corrigendum: Semianalytical wavefunctions and Kohn–Sham exchange–correlation potentials for two-electron atomic systems in two-dimensions (2020 J. Phys. B: At. Mol. Opt. Phys. 53 035001)

Recently, we proposed accurate forms of the wavefunction for two-electron atomic systems in two-dimensions and calculated the exchange–correlation potentials for these systems using the Levy–Perdew–Sahni (LPS) equation. As a part of this work, we reported the results for the chemical potentials (μ) calculated by solving the LPS equation

$$\begin{equation*}\left[-\frac{1}{2}{\nabla }^{2}+{v}_{\text{ext}}\left( \overrightarrow {r\hspace{2pt}}\right)+{v}_{\text{eff}}^{\text{LPS}}\left( \overrightarrow {r\hspace{2pt}}\right)\right]{\rho }^{1/2}\left( \overrightarrow {r\hspace{2pt}}\right)=\mu {\rho }^{1/2}\left( \overrightarrow {r\hspace{2pt}}\right),\end{equation*}$$

directly. For this, we construct the effective potential ${v}_{\text{eff}}^{\text{LPS}}\left( \overrightarrow {r\hspace{2pt}}\right)$ for Le Sech and modified Le Sech wavefunction, and then solve the LPS equation to get the chemical potential and density (ρ). The values so obtained for μ for the modified Le Sech wavefunctions given in table 7 of this paper are not correct. In this erratum, we correct these and give table 7 of the paper mentioned above with updated values of μ for the modified Le Sech wavefunctions.
