In Eq. (2) of the Letter, we derived the expression of UMR based on the Boltzmann transport theory. In the equation, the integration is taken over kx, the momentum along the x direction. Here, the derivative symbol d was missing after the integral. Namely, Eq. (2) should be corrected as (Formula Presented). This typo does not alter any conclusions drawn in the paper.
