## Description

- description: Double-layer quantum systems are promising platforms for realizing
    novel quantum phases. Here, we report a study of quantum oscillations (QOs) in
    a weakly coupled double-layer system composed of a large-angle twisted-double-bilayer
    graphene (TDBG). We quantify the interlayer coupling strength by measuring the
    interlayer capacitance from the QOs pattern at low temperatures, revealing electron–hole
    asymmetry. At high temperatures when SdHOs are thermally smeared, we observe resistance
    peaks when Landau levels (LLs) from two moiré minivalleys are aligned, regardless
    of carrier density; eventually, it results in a 2-fold increase of oscillating
    frequency in D, serving as compelling evidence of the magneto-intersub-band oscillations
    (MISOs) in double-layer systems. The temperature dependence of MISOs suggests
    that electron–electron interactions play a crucial role and the scattering times
    obtained from MISO thermal damping are correlated with the interlayer coupling
    strength. Our study reveals intriguing interplays among Landau quantization, moiré
    band structure, and scatterings.
