## Description

- description: An important route of engineering topological states and excitations
    is to combine superconductors (SC) with the quantum Hall (QH) effect, and over
    the past decade, significant progress has been made in this direction. While typical
    measurements of these states focus on electronic properties, little attention
    has been paid to the accompanying thermal responses. Here, we examine the thermal
    properties of the interface between type-II superconducting electrodes and graphene
    in the QH regime. We use the thermal noise measurement to probe the local electron
    temperature of the superconductor next to the biased interface. Surprisingly,
    the measured temperature rise indicates that the superconductor provides a significant
    thermal conductivity, which is linear in temperature. This suggests electronic
    heat transport and may be unexpected, because the number of the quasiparticles
    in the superconductor should be exponentially suppressed. Instead, we attribute
    the measured electronic heat conductivity to the overlap of the normal states
    in the vortex cores.
