Abstract:We investigate interacting spin susceptibilities in lattice models for T -reversal symmetry-broken Weyl semimetals. We employ a random phase approximation (RPA) method for the spin-SU(2)symmetry-broken case that includes mixtures of ladder and bubble diagrams, beyond a SU(2)symmetric case. Within this approach, the relations between the tendency towards magnetic order and the band structure tilt parameter γ under different temperatures are explored. The critical interaction strength Uc for magnetic ordering de… Show more
