Current theories predict that the magneto-conductance is an extrinsic effect which depends on the relaxation time and is originated by chiral anomaly. We study the intrinsic magneto-conductance of WSM solely due to band topology using semiclassical theory up to the second-order, focusing on planar Hall effect (PHE) where E, B, and Hall current lie in the same plane. For tilted WSM, the linear planar Hall conductivity (PHC) tensor is found to have both symmetric and anti-symmetric components corresponding to, respectively, the extrinsic PHC and intrinsic PHC, which serves as a smoking gun to detect intrinsic PHC experimentally. The Lorentz force in k-space due to field induced Berry curvature is identified as the physical origin of anti-symmetric nature of intrinsic PHC. In order to observe intrinsic PHC, the tilt vector has to make an angle {\\phi} with normal direction of E-B plane. In particular, if {\\phi} = 0 both linear and nonlinear intrinsic PHE is independent of the angle {\\theta} between E and B, and at the same time, an intrinsic chiral magnetic effect emerges with current J ~ E {B^3} {\\hat{B}} sin {\\theta} when chiral anomaly is absent.", "revisions": [ { "version": "v1", "updated": "2022-09-08T02:02:33.000Z" } ], "analyses": { "keywords": [ "intrinsic planar hall effect", "tilted weyl semimetals", "intrinsic phc", "intrinsic chiral magnetic effect emerges", "chiral anomaly" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
