## Description

- description: Periodic systems feature the Hofstadter butterfly spectrum produced
    by Brown– Zak minibands of electrons formed when magnetic field flux through the
    lat- tice unit cell is commensurate with flux quantum and manifested by magneto-
    transport oscillations. Quantum oscillations, such as Shubnikov – de Haas effect
    and Aharonov–Bohm effect, are also characteristic for electronic sys- tems with
    closed orbits in real space and reciprocal space. Here we show the intricate relation
    between these two phenomena by tracing quantum magneto-oscillations to Lifshitz
    transitions in graphene superlattices, where they persist even at relatively low
    fields and very much above liquid-helium temperatures. The oscillations originate
    from Aharonov–Bohm interference on cyclotron tra- jectories that form a kagomé-shaped
    network characteristic for Lifshitz tran- sitions. In contrast to Shubnikov -
    de Haas oscillations, the kagomé oscillations are robust against thermal smearing
    and they can be detected even when the Hofstadter butterfly spectrum is undermined
    by electron’s scattering. We expect that kagome ́ quantum oscillations are generic
    to rotationally-symmetric two-dimensional crystals close to Lifshitz transitions.
