If you has used sparse-ir in your research, and you would like to acknowledge the project in your academic publication, please use the following:

We used the sparse-ir library~\cite{wallerberger2023} based on the intermediate representation~\cite{shinaoka2017} and the sparse sampling~\cite{li2020}.
