| contents | Kubo formulae play a central role in modern spintronics and condensed matter physics, serving as the foundational ground for studying transport responses in the linear regime. In this work, we propose a reformulation of the widely used Kubo-Bastin decompositions that eliminates the need for numerical energy integration. By performing these integrations analytically for generic periodic systems, our approach drastically reduces computational cost and simplifies the evaluation of transport coefficients. |
