Quantum oscillations are usually the manifestation of underlying physical nature in condensed matter systems. Here, we report a new type log-periodic quantum ultraquantum three-dimensional topological materials. Beyond limit (QL), observe involving up to five oscillating cycles (five peaks and dips) on magnetoresistance high-quality single-crystal ZrTe 5 , virtually showing clearest feature discrete scale invariance (DSI). Further, theoretical analyses show that two-body quasi-bound states can be responsible for DSI feature. Our work provides perspective ground state materials beyond QL.
