摘      要：Discrete-scale invariance（DSI） is a phenomenon featuring intriguing log-periodicity that can be rarely observed in quantum ***, we report the log-periodic quantum oscillations in the longitudinal magnetoresistivity(ρ;) and the Hall traces(ρ;) of Hf Te5 crystals, which reveal the DSI in the transport-coefficients *** oscillations in ρ;and ρ;show the consistent log B-periodicity with a phase *** finding of the log B oscillations in the Hall resistance supports the physical mechanism as a general quantum effect originating from the resonant *** with theoretical simulations, we further clarify the origin of the log-periodic oscillations and the DSI in the topological *** work evidences the universality of the DSI in the Dirac materials and provides indispensable information for a full understanding of this novel phenomenon.
