The QAH state can only be observed bellow 1 K, although the magnetic ordering can go beyond 100 K. Electron phonon interactions (EPI) come into play a role on the QAH state due to the raise of temperature. Here we show, based on the density functional perturbation theory (DFPT), that EPI in MBT strongly correlate with the magnetic ordering, septuple layers thickness and electronic band topology.
