The anomalous Thomson coefficient is a function of the anomalous Nernst coefficient, enhanced relative to it and approaching a factor of three at low temperature, with inferred values up to fifteen times larger in CeCrGe3.
Nonlinear thermal and thermoelectric responses are shown to encode quantum geometry and satisfy relations parallel to the Wiedemann-Franz and Mott laws in systems with broken symmetries.
