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.

Nonlinearity tames the skin effect in nonreciprocal active systems to enable stable unidirectional solitonic pulse propagation, shown analytically and in an electrical metamaterial experiment.
Spin-phonon coupling in Kitaev systems produces Fano lineshapes in Raman spectra whose temperature evolution and magnetic-field dependence encode the presence of Majorana fermions and Z2 gauge fluxes.
