However, computing electronic and optical properties of such systems using state-of-the-art methodology is challenging due to their large unit cells. This is particularly so for highly precise all-electron calculations within the framework of many-body perturbation theory, which come with high computational costs. Here, we extend an approach that allows for the efficient calculation of the noninteracting polarizability, previously developed for plane wave basis sets, to the (linearized) augmented plane wave method. This approach is based on an additive ansatz, which computes and superposes the polarizabilities of the individual components in their respective unit cells. We implement this formalism in the\n                    <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                      <a:mrow>\n                        <a:msub>\n                          <a:mi>G<\/a:mi>\n                          <a:mn>0<\/a:mn>\n                        <\/a:msub>\n                        <a:msub>\n                          <a:mi>W<\/a:mi>\n                          <a:mn>0<\/a:mn>\n                        <\/a:msub>\n                      <\/a:mrow>\n                    <\/a:math>\n                    module of the\n                    <b:math xmlns:b=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                      <b:mi mathvariant=\"monospace\">exciting<\/b:mi>\n                    <\/b:math>\n                    code and implement an analogous approach for BSE calculations.
