## Description

- description: 'The interplay between thermal transport properties and topological
    aspects is investigated in a spin-triplet chiral p-wave superconductor Sr2RuO4
    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 Sr2RuO4 in detail. '
