## Description

- description: By introducing first-order quantum phases as topological invariants,
    recent symmetry-analysis based theories have reinvigorated magnetic quantum oscillations
    as a versatile quantum probe for unfolding the Fermi-surface topology along with
    the geometry information, i.e. topo-Fermiology. Here, we demon- strate the comprehensive
    topo-Fermiology of high mobility Rashba 2D electron gases with ultra gate-tunability
    of spin-orbit coupling parameters in few- layer black arsenic. The remarkable
    consistencies with the key theoretical predictions of period doubling in quantum
    oscillations, gate-tunable aperiodic beating patterns, and the symmetry enforced
    Landau level crossing phenomena controlled by the competition between Rashba coupling
    and the Zeeman interaction, which ultimately manifests as all odd-filling factor
    integer quantum Hall effect with superb sensitivity to quantum phases, establish
    topo- Fermiology as an indispensable methodology for studying topological quantum
    matters.
