Abstract
Helicons are transverse electromagnetic modes in three-dimensional (3D) electron systems in the presence of a static magnetic field. These modes have been proposed in isotropic or single Weyl semimetals(WSMs) (Francesco M.D. Pellegrino et al, Phys.\ Rev.\ B {\bf 92}, 201407(R) (2015)). In this work, we introduce a tilt term to investigate helicon modes in gapless WSMs within a semiclassical Boltzmann approach and show that the helicon modes exist in tilted WSMs.
