Query: High Fermi velocities and small cyclotron masses in LaAlGe   We report quantum oscillation measurements of LaAlGe, a Lorentz-violating
type-II Weyl semimetal with tilted Weyl cones. Very small quasiparticle masses
and very high Fermi velocities were detected at the Fermi surface. Whereas
three main frequencies have been observed, angular dependence of two Fermi
surface sheets indicates possible two-dimensional (2D) character despite the
absence of the 2D structural features such as van der Waals bonds. Such
conducting states may offer a good platform for low-dimensional polarized spin
current in magnetic RAlGe (R = Ce, Pr) materials.
