Interface tool from Wannier90 to RESPACK: wan2respack

Abstract

We develop the interface tool $\text{wan2respack}$, which connects $\text{RESPACK}$ (software that derives the low-energy effective Hamiltonians of solids) with $\text{Wannier90}$ (software that constructs Wannier functions). $\text{wan2respack}$ converts the Wannier functions obtained by $\text{Wannier90}$ into those used in $\text{RESPACK}$, which is then used to derive the low-energy effective Hamiltonians of solids. In this paper, we explain the basic usage of $\text{wan2respack}$ and show its application to standard compounds of correlated materials, namely, the correlated metal SrVO${}_3$ and the high-$T_c$ superconductor La${}_2$CuO${}_4$. Furthermore, we compare the low-energy effective Hamiltonians of these compounds using Wannier functions obtained by $\text{Wannier90}$ and those obtained by $\text{RESPACK}$. We confirm that both types of Wannier functions give the same Hamiltonians. This benchmark comparison demonstrates that $\text{wan2respack}$ correctly converts Wannier functions in the $\text{Wannier90}$ format into those in the $\text{RESPACK}$ format.
