  Chiral superconductors exhibit novel transport properties that depend on the
topology of the order parameter, topology of the Fermi surface, the spectrum of
bulk and edge Fermionic excitations, and the structure of the impurity
potential. In the case of electronic heat transport, impurities induce an
anomalous (zero-field) thermal Hall conductivity that is easily orders of
magnitude larger than the quantized edge contribution. The effect originates
from branch-conversion scattering of Bogoliubov quasiparticles by the chiral
order parameter, induced by potential scattering. The former transfers angular
momentum between the condensate and the excitations that transport heat. The
anomalous thermal Hall conductivity is shown to depend to the structure of the
electron-impurity potential, as well as the winding number, $\nu$, of the
chiral order parameter, $\Delta(p)=|\Delta(p)|\,e^{i\nu\phi_{p}}$. The results
provide quantitative formulae for interpreting heat transport experiments
seeking to identify broken T and P symmetries, as well as the topology of the
order parameter for chiral superconductors.
