Abstract

The magneto-optical transport of gapless type-I tilted single Weyl semimetals(WSMs) exhibits suppression of total magnetoconductivities in the presence of orbital magnetic moment(OMM) in linear and nonlinear responses (Yang Gao et al., Phys. Rev. B {\bf 105}, 165307 (2022)). In this work, we extend our study to investigate magnetoconductivities in gapless type-II Weyl semimetals within the semiclassical Boltzmann approach and show the differences that arise compared to type-I Weyl semimetals.
