  Using first-principles calculations we investigate the intrinsic origins of
the anomalous Hall effect (AHE) and the anomalous Nernst effect (ANE) in
antiperovskite ferrimagnet Mn4N. We predict that the AHE is significantly
enhanced under both compressive and tensile strain, however, the ANE generally
decreases under epitaxial strain, except for 1% compressive strain. We connect
this behavior to the evolution of the Berry curvature with strain, suggesting
similar strategies for achieving large AHE and ANE changes with modest amounts
of strain. Finally, we find that the non-monotonic characteristics of the AHE
and ANE stem from the formation and movement of new Weyl points at the
periphery of the Brillouin Zone under compressive and tensile strains.
