摘要

The interplay between thermal transport properties and topological aspects is investigated in a spin-triplet chiral p-wave superconductor Sr_2RuO_4 with strong two dimensionality. We show that thermal Hall conductivity is well described by a temperature linear term and an exponential term in the low-temperature region. While the former term is directly proportional to the so-called Chern number, the latter is associated with the superconducting gap amplitude of the γ band. We also demonstrate that the coefficient of the exponential term changes sign around the Lifshitz transition. Our obtained result may enable us to easily access the physical quantities and topological properties of Sr_2RuO_4 in detail.
