  "abstract": "We study the positive longitudinal magnetoconductivity (LMC) and planar Hall effect as emergent effects of the chiral anomaly in Weyl semimetals, following a recent-developed theory by integrating the Landau quantization with Boltzmann equation. It is found that, in the weak magnetic field regime, the LMC and planar Hall conductivity (PHC) obey $\\cos^{6}\\theta$ and $\\cos^{5}\\theta\\sin \\theta$ dependences on the angle $\\theta$ between the magnetic and electric fields. For higher magnetic fields, the LMC and PHC cross over to $\\cos^{2}\\theta$ and $\\cos\\theta\\sin\\theta$ dependences, respectively. Interestingly, the PHC could exhibit quantum oscillations with varying $\\theta$, due to the periodic-in-$1/B$ oscillations of the chiral chemical potential. When the magnetic and electric fields are noncollinear, the LMC and PHC will deviate from the classical $B$-quadratic dependence, even in the weak magnetic field regime.",
