## Description

- description: Magnetotransport of conventional semiconductor based double layer systems
    with barrier suppressed interlayer tunneling has been a rewarding subject due
    to the emergence of an interlayer coherent state that behaves as an excitonic
    superfluid. Large angle twisted bilayer graphene offers unprecedented strong interlayer
    Coulomb interaction, since both layer thickness and layer spacing are of atomic
    scale and a barrier is no more needed as the twist induced momentum mismatch suppresses
    tunneling. The extra valley degree of freedom also adds richness. Here we report
    the observation of fractional quantum Hall physics at 1/3 total filling for balanced
    layer population in this system. Monte Carlo simulations support that the ground
    state is also an excitonic superfluid but the excitons are composed of fractional
    rather than elementary charges. The observed phase transitions with an applied
    displacement field at this and other fractional fillings are also addressed with
    simulations. They reveal ground states with different topology and symmetry properties.
