Recent works have derived the obital magnetelectric coefficients (OMEC) at finite temperature (fermi surface term[1], intrinsic term in semiclassical approach[2]). In this work, we dirived the intrinsic OMEC with the Kubo formula at finite temperature. In this oral presentation, we will talk about the formalization and some application to specific models.
